 JV6940.The horizontal coordinates were established by GPS observations
 JV6940.and adjusted by the National Geodetic Survey in February 2007.
 JV6940
 JV6940.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6940.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6940
 JV6940.The horizontal coordinates are valid at the epoch date displayed above
 JV6940.which is a decimal equivalence of Year/Month/Day.
 JV6940
 JV6940.The orthometric height was determined by differential leveling and
 JV6940.adjusted in June 1995.
 JV6940
 JV6940.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6940
 JV6940.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6940
 JV6940.The ellipsoidal height was determined by GPS observations
 JV6940.and is referenced to NAD 83.
 JV6940
 JV6940.The dynamic height is computed by dividing the NAVD 88
 JV6940.geopotential number by the normal gravity value computed on the
 JV6940.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6940.degrees latitude (g = 980.6199 gals.).
 JV6940
 JV6940.The modeled gravity was interpolated from observed gravity values.

 HV9263.This mark is at Andrews Afb Airport (ADW)
 HV9263
 HV9263.The horizontal coordinates were established by GPS observations
 HV9263.and adjusted by the National Geodetic Survey in February 2007.
 HV9263
 HV9263.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV9263.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV9263
 HV9263.The horizontal coordinates are valid at the epoch date displayed above
 HV9263.which is a decimal equivalence of Year/Month/Day.
 HV9263
 HV9263.The orthometric height was determined by differential leveling and
 HV9263.adjusted in August 1994.
 HV9263
 HV9263.Photographs are available for this station.
 HV9263
 HV9263.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV9263
 HV9263.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV9263
 HV9263.The ellipsoidal height was determined by GPS observations
 HV9263.and is referenced to NAD 83.
 HV9263
 HV9263.The dynamic height is computed by dividing the NAVD 88
 HV9263.geopotential number by the normal gravity value computed on the
 HV9263.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV9263.degrees latitude (g = 980.6199 gals.).
 HV9263
 HV9263.The modeled gravity was interpolated from observed gravity values.

 JV2900.The horizontal coordinates were established by GPS observations
 JV2900.and adjusted by the National Geodetic Survey in February 2007.
 JV2900
 JV2900.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV2900.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV2900
 JV2900.The horizontal coordinates are valid at the epoch date displayed above
 JV2900.which is a decimal equivalence of Year/Month/Day.
 JV2900
 JV2900.The orthometric height was determined by differential leveling and
 JV2900.adjusted in June 1991.
 JV2900
 JV2900.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV2900
 JV2900.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV2900
 JV2900.The ellipsoidal height was determined by GPS observations
 JV2900.and is referenced to NAD 83.
 JV2900
 JV2900.The dynamic height is computed by dividing the NAVD 88
 JV2900.geopotential number by the normal gravity value computed on the
 JV2900.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV2900.degrees latitude (g = 980.6199 gals.).
 JV2900
 JV2900.The modeled gravity was interpolated from observed gravity values.

 JU3483.The horizontal coordinates were established by GPS observations
 JU3483.and adjusted by the National Geodetic Survey in February 2007.
 JU3483
 JU3483.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JU3483.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JU3483
 JU3483.The horizontal coordinates are valid at the epoch date displayed above
 JU3483.which is a decimal equivalence of Year/Month/Day.
 JU3483
 JU3483.The orthometric height was determined by differential leveling and
 JU3483.adjusted in August 1994.
 JU3483
 JU3483.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JU3483
 JU3483.The Laplace correction was computed from DEFLEC09 derived deflections.
 JU3483
 JU3483.The ellipsoidal height was determined by GPS observations
 JU3483.and is referenced to NAD 83.
 JU3483
 JU3483.The dynamic height is computed by dividing the NAVD 88
 JU3483.geopotential number by the normal gravity value computed on the
 JU3483.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JU3483.degrees latitude (g = 980.6199 gals.).
 JU3483
 JU3483.The modeled gravity was interpolated from observed gravity values.

 HV6657
 HV6657'DESCRIBED BY COAST AND GEODETIC SURVEY 1912 (JBB)
 HV6657'STATION IS ON E SIDE OF CHESAPEAKE BAY, NEAR THE S END OF BARREN
 HV6657'ISLAND, ABOUT 160 METERS NW OF A POINT WHERE THE ISLAND CONTRACTS
 HV6657'TO A LONG NARROW NECK OF LAND, ON A STRIP OF FIRM SANDY SOIL,
 HV6657'ABOUT 50 FEET BACK FROM THE SHORE LINE, AND ABOUT 50 FEET S OF
 HV6657'PINE-TREE GROWTH.  MARKED BY A CEMENT BLOCK 6- BY 6- 24-INCHES,
 HV6657'EXTENDING 6 INCHES ABOVE THE SURFACE, WITH A TRIANGLE, THE YEAR
 HV6657'1912 AND THE LETTERS C.G.S. IN THE TOP.  SUBSURFACE MARK IS A
 HV6657'CEMENT BLOCK 6- BY 6- BY 9-INCHES, BURIED 3 FEET BELOW THE
 HV6657'SURFACE.  NAIL IN CENTER OF TOP BLOCK MARKS POINT.  REFERENCE
 HV6657'MARKS ARE TRIANGULAR BLAZES IN PINE TREES, WITH THE
 HV6657'FOLLOWING DISTANCES AND BEARINGS--TREE A, 86 FEET, N 42 DEG

 HV6657
 HV6657'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1929 (JS)
 HV6657'A SEARCH OF FORTY-FIVE MINUTES WAS MADE BY FOUR MEN BUT STATION
 HV6657'WAS NOT FOUND.  A PINE TREE WITH A TRIANGULAR BLAZE ON THE SEAWARD
 HV6657'SIDE WAS FOUND AND IT IS BELIEVED THIS WAS TREE B, ONE OF THE
 HV6657'REFERENCE MARKS REFERRED TO IN THE OLD DESCRIPTION.
 HV6657'
 HV6657'THIS TREE WAS ONLY 18 FEET NE OF THE HIGH-WATER LINE, AND
 HV6657'JUDGING FROM THE DISTANCE (104 FEET) AND BEARING (S 51 DEG 19 MIN E)
 HV6657'GIVEN IN THE OLD DESCRIPTION, IT SEEMS THAT THE STATION HAS BEEN
 HV6657'WASHED AWAY.  SEVERAL OTHER PINE TREES STOOD IN THE VICINITY BUT
 HV6657'NO OTHER BLAZE WAS FOUND.
 HV6657'
 HV6657'IT IS RECOMMENDED THAT STATION BE CONSIDERED LOST AND ELIMINATED
 HV6657'FROM THE RECORDS.

 HV7257'OF CHESAPEAKE BEACH.  STATION IS ABOUT 110 FEET ABOVE HIGH WATER
 HV7257'AND 7 YARDS BACK FROM THE EDGE OF HIGHEST BLUFF IN THE VICINITY.
 HV7257'THE GROUND FALLS AWAY RAPIDLY TO THE SW AND W OF THE STATION, AND
 HV7257'IS COVERED WITH BRUSH AND SMALL LOCUST TREES.  A CULTIVATED FIELD
 HV7257'EXTENDS TO WITHIN 10 YARDS OF THE STATION ON THE NW.  IN 1907 A
 HV7257'VISTA WAS CLEARED IN THE DIRECTION OF STATION BLAKE, AZIMUTH S 24
 HV7257'DEG 05 MIN W.  THIS INVOLVED THE CUTTING OF SOME LARGE TREES.

 HV7257
 HV7257'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1944 (LPR)
 HV7257'STATION NOT FOUND.  DESCRIPTION ADEQUATE FOR LOCATION EXCEPT NONE
 HV7257'OF THE BLAZED TREES REMAIN.  THE REFERENCE MARK OF 1908, STANDARD
 HV7257'MONUMENT OF M.S.F.S., WAS FOUND.  THIS LATTER MARK IS IN GOOD
 HV7257'CONDITION AND SOLID.  IT NOW PROJECTS ABOUT 2 INCHES ABOVE GROUND.
 HV7257'FROM MEASUREMENTS THE ORIGINAL STATION IS NOW ABOUT 6 FEET FROM
 HV7257'THE EDGE OF THE CLIFF.  THE SURFACE MARK WAS NOT FOUND AFTER
 HV7257'SEARCH.  THE STATION PROBABLY COULD BE FOUND BY ACCURATE
 HV7257'DETERMINATION OF THE AZIMUTH OF THE STATION ON THE GROUND FROM THE
 HV7257'1908 REFERENCE MARK AND DIGGING FOR THE UNDERGROUND MARKS.  A
 HV7257'BLAZE WAS CUT ON A TREE ABOUT 10 FEET SW OF THE 1908 REFERENCE MARK.

 HV1091.and adjusted by the National Geodetic Survey in February 2007.
 HV1091
 HV1091.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV1091.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV1091
 HV1091.The horizontal coordinates are valid at the epoch date displayed above
 HV1091.which is a decimal equivalence of Year/Month/Day.
 HV1091
 HV1091.The orthometric height was determined by differential leveling and
 HV1091.adjusted in June 1991.
 HV1091
 HV1091.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV1091
 HV1091.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV1091
 HV1091.The ellipsoidal height was determined by GPS observations
 HV1091.and is referenced to NAD 83.
 HV1091
 HV1091.The dynamic height is computed by dividing the NAVD 88
 HV1091.geopotential number by the normal gravity value computed on the

 HV6204
 HV6204'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1947 (MJT)
 HV6204'THE STATION WAS RECOVERED AS DESCRIBED AND THE STATION MARK WAS
 HV6204'FOUND TO BE IN GOOD CONDITION.  THE STATION MARK WAS VERY CLOSE TO
 HV6204'THE BAY, AND DUE TO EROSION OF THE BANK, IT WAS IMPOSSIBLE TO
 HV6204'BUILD A TOWER OVER IT.  A STATION, BENTON 2, WAS ESTABLISHED,
 HV6204'COMPLETE WITH REFERENCE MARKS AND AZIMUTH MARK.  BOTH REFERENCE
 HV6204'MARKS ESTABLISHED IN 1934 HAVE DISAPPEARED DUE TO EROSION OF THE
 HV6204'BANK, AND THE AZIMUTH MARK IS PRESUMED LOST DUE TO GRADING OF
 HV6204'ADJACENT PROPERTY.  TO REACH THE STATION FROM THE MATAPEAKE
 HV6204'FERRY LANDING, GO E 0.4 MILE, TURN RIGHT ON A BLACKTOP ROAD
 HV6204'FOR 1.5 MILES, TURN RIGHT BETWEEN TWO BRICK PILLARS, BEARING
 HV6204'LEFT AROUND BRICK HOUSE FOR 0.4 MILE, TURN LEFT FOR 0.2 MILE
 HV6204'TO A WHITE CONCRETE HOUSE ON THE RIGHT.  THE STATION IS 100 YARDS
 HV6204'W OF THE HOUSE, 15 FEET E OF THE BANK, AND 16.61 FEET W OF
 HV6204'BENTON 2, WHICH IS 8 INCHES BELOW THE SURFACE OF THE
 HV6204'GROUND.  THE MARK PROJECTS ABOUT 2 INCHES AND THE DISK IS
 HV6204'STAMPED BENTON 1934.

 HV6204
 HV6204'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1960 (GFW)
 HV6204'THE STATION SHOULD BE CONSIDERED LOST.  APPROX. 100 FEET OF SHORE
 HV6204'HAS ERODED SINCE 1947 (LAST RECOVERY).  MEASUREMENTS INDICATE THAT
 HV6204'THE STATION HAS WASHED OUT.

 HV6204                          STATION RECOVERY (1970)
 HV6204
 HV6204'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1970 (LFS)
 HV6204'STATION WAS SEARCHED FOR BUT NOT RECOVERED.  IN 1947 IT WAS
 HV6204'REPORTED BY M.J.T. THAT THE STATION WAS RECOVERED BUT DUE TO
 HV6204'EROSION IT WAS TO CLOSE TO THE BAY TO BUILD A TOWER OVER SO AT
 HV6204'THAT TIME STATION BENTON 2 WAS ESTABLISHED.  IT WAS ALSO REPORTED
 HV6204'AT THAT TIME THE REFERENCE MARKS WERE GONE BECAUSE OF EROSION.
 HV6204'THE AZIMUTH MARK WAS PRESUMED LOST DUE TO GRADING OF ADJACENT
 HV6204'PROPERTY.  RECENTLY A MARK WAS REPORTED FOUND WHICH WHEN
 HV6204'INVESTIGATED WAS FOUND TO BE REFERENCE MARK NO. 1 (AZIMUTH
 HV6204'MARK) AND LYING IN MARSHLAND.  THE DISK WAS RECLAIMED AT THIS
 HV6204'TIME.

 HV5318'IS NOW 2.67 METERS FROM THE EDGE OF THE BLUFF.  THE BLAZED WALNUT
 HV5318'TREE WAS RECOVERED.
 HV5318'
 HV5318'THE REFERENCE MARK MENTIONED IN THE DESCRIPTION WAS PROVED TO
 HV5318'HAVE BEEN DESTROYED.  THE WALNUT IS NOW DEAD.  THE BLAZE WAS RECUT
 HV5318'SO THAT IT IS PLAINLY VISIBLE TO A PERSON WALKING ALONG THE EDGE
 HV5318'OF THE BLUFF IN THE VICINITY OF THE STATION.  THE STATION MARK WAS
 HV5318'COVERED WITH EARTH AND SOD TO A DEPTH OF ABOUT FOUR INCHES.  A
 HV5318'SMALL PILE OF BRUSH, BOARDS AND DEAD LIMBS WAS PLACED OVER THE
 HV5318'STATION MARK TO FACILITATE RECOVERY BY ANY SUBSEQUENT PARTY
 HV5318'SEARCHING THIS SEASON.
 HV5318'
 HV5318'THE STATION SHOULD HAVE ADEQUATE PERMANENT REFERENCE MARKS PUT
 HV5318'IN AS SOON AS PRACTICABLE.

 HV8939.The horizontal coordinates were established by GPS observations
 HV8939.and adjusted by the National Geodetic Survey in February 2007.
 HV8939
 HV8939.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV8939.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV8939
 HV8939.The horizontal coordinates are valid at the epoch date displayed above
 HV8939.which is a decimal equivalence of Year/Month/Day.
 HV8939
 HV8939.The orthometric height was determined by differential leveling and
 HV8939.adjusted in August 1994.
 HV8939
 HV8939.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV8939
 HV8939.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV8939
 HV8939.The ellipsoidal height was determined by GPS observations
 HV8939.and is referenced to NAD 83.
 HV8939
 HV8939.The dynamic height is computed by dividing the NAVD 88
 HV8939.geopotential number by the normal gravity value computed on the
 HV8939.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV8939.degrees latitude (g = 980.6199 gals.).
 HV8939
 HV8939.The modeled gravity was interpolated from observed gravity values.

 HV5827
 HV5827'DESCRIBED BY MD DEPT OF NAT RES 1974 (CLN)
 HV5827'THE STATION IS LOCATED ON A SMALL ISLAND AT THE MOST SOUTHWEST POINT
 HV5827'OF LAND ON HOOD POINT.  IT IS ABOUT 10 MILES EAST OF ANNAPOLIS
 HV5827'AND ABOUT 2 MILES SOUTH OF THE HIGHWAY BRIDGE OVER KENT NARROWS.
 HV5827'THE PROPERTY IS OWNED BY THE STATE OF MARYLAND.
 HV5827'
 HV5827'THIS STATION CAN BE REACHED BY BOAT ONLY.  FROM THE HIGHWAY
 HV5827'BRIDGE FOR U.S. HIGHWAYS 50 AND 301 OVER KENT NARROWS, SAIL
 HV5827'SOUTHERLY THROUGH KENT NARROWS FOR ABOUT 2 MILES TO THE SMALL
 HV5827'ISLAND JUST OFF HOOD POINT AND THE STATION IN THE CENTER OF THE 30
 HV5827'FOOT ROUND ISLAND.
 HV5827'
 HV5827'THE STATION MARK IS A MARYLAND DEPARTMENT OF NATURAL RESOURCES
 HV5827'MONUMENT WHICH BEARS THE NAME BONNET 2 MSFC.  THE POINT IS MARKED
 HV5827'BY A 3/4 INCH ROUND IRON PEG SET IN THE TOP OF A 10-INCH ROUND
 HV5827'CONCRETE MONUMENT WHICH IS FLUSH WITH THE SURFACE.  THE PEG STICKS
 HV5827'UP ABOVE THE CONCRETE MONUMENT ABOUT 4 INCHES AND THERE IS A
 HV5827'SMALL CENTER PUNCH HOLE IN THE CENTER OF THE PEG.  IT IS 46 FEET
 HV5827'NORTHEAST OF THE MOST SOUTHWEST POINT OF THE ISLAND, 48 FEET
 HV5827'NORTHWEST OF THE MOST SOUTHEAST POINT OF THE ISLAND AND 30
 HV5827'FEET SOUTH OF THE MOST NORTH POINT.  A WITNESS POST WAS SET
 HV5827'NEAR WHERE OLD TRIANGULATION STATION BONNET MSFC 1909 WAS FOUND
 HV5827'AND THE WITNESS POST IS 22.5 FEET NORTHWEST OF THIS NEW
 HV5827'STATION.
 HV5827'
 HV5827'THIS ISLAND IS VERY SMALL AND THE ONLY SOLID GROUND IN THE AREA IS
 HV5827'IN THE CENTER OF THE ISLAND WHERE THE STATION MARK IS LOCATED.
 HV5827'THERE IS NO SUITABLE PLACE WITHIN REASONABLE DISTANCE TO ESTABLISH
 HV5827'REFERENCE MARKS.
 HV5827'
 HV5827'SEVERAL INTERSECTIONS STATIONS WERE OBSERVED FROM THIS STATION
 HV5827'AND MOST ANY OF THEM MAY BE USED AS AN AZIMUTH MARK FOR THIS
 HV5827'STATION.
 HV5827'
 HV5827'THE POSITION OF THIS STATION WAS DETERMINED BY TRAVERSEING FROM OLD
 HV5827'TRIANGULATION STATION BONNET MSFC 1909.

 JU3533'BOUNDARY MONUMENT 55 DE-MD IS AN 11.5-INCH X 11.5-INCH LIMESTONE SHAFT
 JU3533'THAT PROJECTS 25.5 INCHES AND IS IN GOOD CONDITION.  ACCORDING TO THE
 JU3533'DELAWARE GEOLOGICAL SURVEY, THE MASON-DIXON TANGENT LINE SURVEY SET
 JU3533'THIS BOUNDARY MONUMENT STONE IN 1766.  THE 1961 CGS DESCRIPTION IS
 JU3533'INCORRECT.
 JU3533'THE STONE DOES NOT HAVE THE LETTER P CUT INTO THE EAST SIDE AND THE
 JU3533'LETTER M CUT INTO THE WEST SIDE.  IT IS A CROWN STONE WITH THE PENN
 JU3533'FAMILY ARMORIAL CREST CUT INTO THE EAST FACE AND THE CALVERT FAMILY
 JU3533'CREST CUT INTO THE WEST FACE.  THE CALVERT FAMILY CREST ON THE WEST
 JU3533'FACE IS VERY WEATHERED AND IN POOR CONDITION. THE PENN FAMILY CREST ON
 JU3533'THE EAST FACE IS WEATHERED BUT IN GOOD CONDITION.
 JU3533'THE STONE LEANS ABOUT TWO DEGREES TO THE WEST.  THE FLUTING IS VERY
 JU3533'WEATHERED BUT VISIBLE ON ALL SIDES, EXCEPT WHERE LOST TO CHIPPING.
 JU3533'THE TOP IS ROUGHLY PYRAMIDAL, BUT WELL WEATHERED AND ROUNDED.  THERE
 JU3533'IS A SMALL CHISELED CROSS NEAR THE CENTER OF THE TOP, BUT IT IS BARELY
 JU3533'DISCERNABLE.  THE LOWER THIRD OF THE STONE IS OBSCURED BY THICK
 JU3533'UNDERGROWTH.
 JU3533'THE STONE IS LOCATED AT THE SOUTH EDGE OF A LARGE FIELD OPENING ON THE
 JU3533'SOUTH SIDE OF MD RTE 291/DE RTE 6, AND AT THE NORTH END OF A
 JU3533'NORTH-SOUTH HEDGEROW THAT SEPARATES TWO CULTIVATED FIELDS. THE
 JU3533'DELAWARE SIDE OF THE FIELD ENTRANCE IS IN THE BLACKISTON WILDLIFE AREA
 JU3533'RESERVE.  THE STONE IS SURROUNDED BY THREE I-BEAMS, EACH OF WHICH
 JU3533'PROJECTS ABOUT THREE FEET.
 JU3533'EACH ARE LOCATED ABOUT 1.3 FEET (0.40 M) FROM THE STONE AND ARE SET
 JU3533'NORTHWEST, NORTHEAST AND DUE SOUTH OF THE STONE, RESPECTIVELY.  THE
 JU3533'STONE IS LOCATED 79 FEET (24.08 M) SOUTH OF THE SOUTH EDGE OF PAVEMENT
 JU3533'OF MD RTE 291/DE RTE 6.
 JU3533'THE STONE LIES 1.3 FEET (0.40 M) SOUTH OF AN ORANGE CARSONITE WITNESS
 JU3533'POST, 4.6 FEET (1.40 M) NORTHEAST OF A SIX-INCH CYPRESS TREE, 4.0 FEET
 JU3533'(1.22 M) NORTHWEST OF A SIX-INCH TREE, 118.3 FEET (36.06 M) SOUTH OF A
 JU3533'ROUND METAL POLE SUPPORTING A HISTORICAL MARKER THAT DESCRIBES THE
 JU3533'MASON AND DIXON SURVEY.
 JU3533'IT IS 50.8 FEET (15.48 M) SOUTHWEST OF THE MORE SOUTHERLY OF TWO FOUR
 JU3533'INCH BY FOUR INCH TIMBERS THAT SUPPORT A SIGN FOR THE WILDLIFE AREA,
 JU3533'AND 65.2 FEET (19.87 M) SOUTH OF THE SOUTH MOST METAL LEG OF A BLUE

 JV6950.The horizontal coordinates were established by GPS observations
 JV6950.and adjusted by the National Geodetic Survey in February 2007.
 JV6950
 JV6950.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6950.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6950
 JV6950.The horizontal coordinates are valid at the epoch date displayed above
 JV6950.which is a decimal equivalence of Year/Month/Day.
 JV6950
 JV6950.The orthometric height was determined by differential leveling and
 JV6950.adjusted in June 1995.
 JV6950
 JV6950.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6950
 JV6950.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6950
 JV6950.The ellipsoidal height was determined by GPS observations
 JV6950.and is referenced to NAD 83.
 JV6950
 JV6950.The dynamic height is computed by dividing the NAVD 88
 JV6950.geopotential number by the normal gravity value computed on the

 HV4942
 HV4942'DESCRIBED BY COAST AND GEODETIC SURVEY 1928 (CP)
 HV4942'STATION IS ON THE E SHORE OF POTOMAC RIVER JUST S OF FIRST POINT
 HV4942'S OF MARSHALL HALL ON THE CULTIVATED TOBACCO FIELD BELONGING TO
 HV4942'MR. TIBBETTS.  STATION IS BACK FROM THE EDGE OF THE BLUFF ABOUT 15
 HV4942'FEET.  MARK IS ABOUT 1 FOOT BELOW SURFACE OF FIELD STAMPED BRISCOE
 HV4942'2 1928.  SEARCH WAS MADE FOR MARK ESTABLISHED BY P.C. DORAN BUT
 HV4942'IT WAS SET TWO FEET BELOW SURFACE AND AS TOBACCO WAS GROWING ONLY
 HV4942'A LIMITED AREA WAS AVAILABLE FOR SEARCHING.  HIS MARK STAMPED
 HV4942'BRISCOE 1928.
 HV4942'
 HV4942'UNDERGROUND, AND REFERENCE MARKS ARE STANDARD BRONZE DISKS SET IN
 HV4942'CONCRETE.

 HV4942
 HV4942'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1929 (EBL)
 HV4942'THE STATION WAS RECOVERED ACCORDING TO THE DESCRIPTION OF CHARLES
 HV4942'PIERCE, IN 1928.  THE MARK FOUND HAD A SIGNAL STANDING, AND WAS
 HV4942'STAMPED BRISCOE 2 1928.  A LARGE LOCUST TREE, STANDING DIRECTLY
 HV4942'BETWEEN THE STATION AND THE SHORE WAS CUT IN CLEARING LINES OF
 HV4942'SIGHT, WHICH FACT SHOULD AID IN THE RECOVERY OF THE STATION.

 HV4942
 HV4942'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1938 (TMP)
 HV4942'BOTH REFERENCE MARKS AND THE NEARBY TRIANGULATION STATION
 HV4942'U.S.E. HYDROGRAPHIC SIGNAL, 1928 ARE DESTROYED.  THESE MARKS WERE
 HV4942'FOUND WHERE THEY HAD FALLEN OFF THE CAVING BLUFF.  THE STATION
 HV4942'MARK OF BRISCOE 2 IS PROBABLY STILL IN EXISTENCE, BUT DUE TO THE
 HV4942'FACT THAT THE REFERENCE MARKS ARE GONE AND THE MARK IS SET BELOW
 HV4942'THE SURFACE, IT CAN ONLY BE RECOVERED BY MEANS OF ANGLES.
 HV4942
 HV4942                          STATION RECOVERY (1948)
 HV4942
 HV4942'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1948
 HV4942'STATION WAS NOT RECOVERED.  THE REMAINS OF CONCRETE REFERENCE
 HV4942'MONUMENTS, MENTIONED IN 1938 RECOVERY NOTE OF T.M.P., JR., WERE
 HV4942'FOUND ON THE SHORE AND THE LARGE LOCUST STUMP MENTIONED IN 1929
 HV4942'RECOVERY NOTE OF E.B.L. WAS ALSO FOUND.
 HV4942'
 HV4942'AFTER COMBING THE AREA WITH A MINE DETECTOR FOR OVER ONE HOUR
 HV4942'THE SEARCH WAS ABANDONED.
 HV4942'
 HV4942'THE MARK IS THOUGHT TO BE IN EXISTANCE BUT RECOVERY IS NOT
 HV4942'PRACTICABLE WITHOUT USING A THEODOLITE OR PLANETABLE.
 HV4942
 HV4942                          STATION RECOVERY (1959)
 HV4942
 HV4942'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1959 (CAS)
 HV4942'STATION WAS NOT RECOVERED.  THERE WAS TOO MUCH DEBRIS WASHED UP ON
 HV4942'THE BEACH TO DEFINITELY IDENTIFY THE REMAINS OF THE CONCRETE
 HV4942'REFERENCE MONUMENTS MENTIONED IN THE 1938 RECOVERY NOTE BY
 HV4942'T.M.P., JR. AND THE 1948 RECOVERY NOTE BY THE DIVISION OF
 HV4942'PHOTOGRAMMETRY.  THREE LARGE LOCUST STUMPS WERE FOUND IN THIS
 HV4942'AREA AND IT WAS IMPOSSIBLE TO IDENTIFY THE ONE MENTIONED IN THE
 HV4942'1938 AND 1948 RECOVERY NOTES.
 HV4942'
 HV4942'THERE WAS NO LARGE, MONUMENT TYPE, CONCRETE BLOCK FOUND ON THE
 HV4942'BEACH AND IT IS THOUGHT THAT THE STATION STILL EXISTS AND WILL
 HV4942'PROBABLY BE EXPOSED BY THE ERODING BLUFF IN THE NEXT FEW YEARS.

 JV5410'
 JV5410'DIRECTIONS ARE VERY ADEQUATE.  THE STATION IS UNDER THE COTTAGE
 JV5410'NOW OWNED BY MRS. PLUM.  THERE IS ENOUGH CRAWL SPACE UNDER THE
 JV5410'COTTAGE TO REACH THE STATION, BUT IT WOULD NOT BE ACCESSIBLE TO
 JV5410'SURVEYOR. STATION WAS SEEN BY RECOVERER.  RM 1 WAS UP-ROOTED BY A
 JV5410'TREE DURING HURRICANE AGNES AND IS LAYING ON ITS SIDE AND BURIED
 JV5410'2/3 INTO THE GROUND.  THE 1/3 ABOVE THE GROUND MAKES IT DIFFICULT
 JV5410'TO CUT THE GRASS AND MRS. PLUM WOULD LIKE TO HAVE IT REMOVED.  NO
 JV5410'SIGN OF RM 2.  RM 3 IS IN GOOD CONDITION, BUT NOW ONLY 1 FOOT FROM
 JV5410'PAVED ROAD DUE TO RESURFACING OF THE ROAD.

 HV8841.This mark is at Cambridge-Dorchester Airport (CGE)
 HV8841
 HV8841.The horizontal coordinates were established by GPS observations
 HV8841.and adjusted by the National Geodetic Survey in February 2007.
 HV8841
 HV8841.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV8841.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV8841
 HV8841.The horizontal coordinates are valid at the epoch date displayed above
 HV8841.which is a decimal equivalence of Year/Month/Day.
 HV8841
 HV8841.The orthometric height was determined by GPS observations and a
 HV8841.high-resolution geoid model.
 HV8841
 HV8841.GPS derived orthometric heights for airport stations designated as
 HV8841.PACS or SACS are published to 2 decimal places.  This maintains
 HV8841.centimeter relative accuracy between the PACS and SACS.  It does
 HV8841.not indicate centimeter accuracy relative to other marks which are
 HV8841.part of the NAVD 88 network.
 HV8841
 HV8841.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV8841
 HV8841.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV8841
 HV8841.The ellipsoidal height was determined by GPS observations
 HV8841.and is referenced to NAD 83.

 JV6465
 JV6465.The horizontal coordinates were established by GPS observations
 JV6465.and adjusted by the National Geodetic Survey in February 2007.
 JV6465
 JV6465.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6465.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6465
 JV6465.The horizontal coordinates are valid at the epoch date displayed above
 JV6465.which is a decimal equivalence of Year/Month/Day.
 JV6465
 JV6465.The orthometric height was determined by GPS observations and a
 JV6465.high-resolution geoid model.
 JV6465
 JV6465.GPS derived orthometric heights for airport stations designated as
 JV6465.PACS or SACS are published to 2 decimal places.  This maintains
 JV6465.centimeter relative accuracy between the PACS and SACS.  It does
 JV6465.not indicate centimeter accuracy relative to other marks which are
 JV6465.part of the NAVD 88 network.
 JV6465
 JV6465.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6465
 JV6465.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6465
 JV6465.The ellipsoidal height was determined by GPS observations

 AA9294.The horizontal coordinates were established by GPS observations
 AA9294.and adjusted by the National Geodetic Survey in February 2007.
 AA9294
 AA9294.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 AA9294.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 AA9294
 AA9294.The horizontal coordinates are valid at the epoch date displayed above
 AA9294.which is a decimal equivalence of Year/Month/Day.
 AA9294
 AA9294.The orthometric height was determined by GPS observations and a
 AA9294.high-resolution geoid model.
 AA9294
 AA9294.GPS derived orthometric heights for airport stations designated as
 AA9294.PACS or SACS are published to 2 decimal places.  This maintains
 AA9294.centimeter relative accuracy between the PACS and SACS.  It does
 AA9294.not indicate centimeter accuracy relative to other marks which are
 AA9294.part of the NAVD 88 network.
 AA9294
 AA9294.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AA9294
 AA9294.The Laplace correction was computed from DEFLEC09 derived deflections.
 AA9294
 AA9294.The ellipsoidal height was determined by GPS observations
 AA9294.and is referenced to NAD 83.

 HV7180
 HV7180'DESCRIBED BY COAST AND GEODETIC SURVEY 1942 (GWL)
 HV7180'THE STATION IS AT CHALK POINT AT THE W END OF NORTH SHORE DRIVE ON
 HV7180'LOT NO.1 WHICH IS THE PROPERTY OF MR. GEORGE C. HEIDER.  THE MARK
 HV7180'IS 22.8 FEET SW OF AN OLD OAK TREE, 28 FEET S OF A PROPOSED
 HV7180'BREAKWATER, ABOUT 10 FEET BACK OF THE PRESENT BANK, AND 24.4 FEET
 HV7180'NW OF THE NW CORNER OF MR. HEIDERS PROPOSED HOUSE.  THE
 HV7180'CONSTRUCTION CREW WERE BUILDING THE BASEMENT OF THE HOUSE AT TIME
 HV7180'OF DESCRIBING THIS STATION.  THE MARK IS FLUSH WITH THE GROUND
 HV7180'AND IS STAMPED CHALK 2 1933, WHILE IN REALITY IT IS NOW CHALK 3
 HV7180'1942.  A NEW DISK AND CONCRETE FOR NEW MARK WAS NOT AVAILABLE AND
 HV7180'SO THE OLD MARKS WERE DUG UP AND MOVED TO THE NEW POSITION IN
 HV7180'ORDER TO PRESERVE THIS STATION AS THE CONSTRUCTION CREW FOR THE
 HV7180'NEW HOUSE WOULD HAVE DESTROYED THE OLD MARKS IN ABOUT 1/2 HOUR.
 HV7180'THE OLD REFERENCE MARK WAS MOVED TO THE NEW POSITION AND WAS
 HV7180'INADVERTENTLY POINTED WEST INSTEAD OF NORTH TO THE STATION.  THE
 HV7180'DISK IS STAMPED CHALK 2 1933 BUT IS THE REFERENCE MARK FOR CHALK 3
 HV7180'1942.  NO ADDITIONAL REFERENCE MARK COULD BE ESTABLISHED BECAUSE
 HV7180'OF THE LACK OF A DISK AND MATERIAL AND THE STAMPING COULD NOT BE
 HV7180'CHANGED FOR THE SAME REASON.

 HV7180                          STATION RECOVERY (1960)
 HV7180
 HV7180'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1960 (GFW)
 HV7180'STATION WAS NOT FOUND AFTER AN HOURS SEARCH BY 2 MEN.  THERE WAS
 HV7180'ONE REFERENCE MARK FOUND, STAMPED CHALK 1933.  HOWEVER, THIS
 HV7180'REFERENCE MARK DOES NOT AGREE WITH THE DESCRIPTION BY G.W.L. IN
 HV7180'1942.  THE ARROW OF THE MARK WAS POINTED DUE E. INSTEAD OF DUE
 HV7180'WEST.  IT IS RECOMMENDED THIS STATION BE CLASSED AS LOST.

 HV6682'STATION WAS RECOVERED AND FOUND IN GOOD CONDITION.  REFERENCE MARK
 HV6682'1, REFERENCE MARK 2, AND THE AZIMUTH MARK HAVE BEEN RESET BY THE
 HV6682'MARYLAND STATE ROADS COMMISSION.  THE TWO REFERENCE MARKS ARE IN
 HV6682'GOOD CONDITION IN THEIR NEW LOCATIONS, BUT THE AZIMUTH MARK COULD
 HV6682'NOT BE FOUND.  THE ORIGINAL DESCRIPTION IS ADEQUATE AND CORRECT
 HV6682'EXCEPT FOR THE TWO REFERENCE MARKS WHICH HAVE BEEN MOVED.
 HV6682'
 HV6682'NEW DESCRIPTION FOR REFERENCE MARKS FOLLOWS--
 HV6682'
 HV6682'REFERENCE MARK 1 IS SE OF THE STATION, 55.2 FEET SE OF THE SE
 HV6682'CORNER OF A HOUSE, 13 FEET S OF DRIVEWAY LEADING TO THE HOUSE,
 HV6682'AND 52 FEET W OF THE CENTER LINE OF THE HIGHWAY.  IT IS A BRONZE

 HV6682
 HV6682'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1977 (CLN)
 HV6682'THE STATION SURFACE MARK WAS FOUND DESTROYED, THE SUB-SURFACE
 HV6682'DISK WAS FOUND IN GOOD CONDITION.  REFERENCE MARKS ONE AND TWO
 HV6682'WERE FOUND TO HAVE BEEN HIT BY LARGE MACHINERY AND THEY WERE
 HV6682'LEANING AND OUT OF POSITION.  THE AZIMUTH MARK WAS BELIEVED
 HV6682'DESTROYED BY ROAD CONSTRUCTION.  IT WAS REPORTED IN JUNE,
 HV6682'1973, THAT A NEW ROAD WAS TO BE CONSTRUCTED, AND IT WOULD
 HV6682'BE VERY NEAR THE STATION MARK, HOWEVER ONLY A 1-1/2 FOOT CUT
 HV6682'WAS TO BE MADE WHERE THE STATION WAS LOCATED.  IN JUNE, 1973,
 HV6682'THE STATION SUB-SURFACE DISK WAS LOWERED TO 48 INCHES BELOW THE
 HV6682'SURFACE AND IN THE EXACT LOCATION AS THE OLD POSITION OF THE
 HV6682'DISK.  ALSO, AT THAT TIME A NEW REFERENCE MARK 3 AND SEVERAL
 HV6682'TEMPORARY POINTS WERE SET SO THE STATION COULD BE LOCATED
 HV6682'AFTER THE CONSTRUCTION WAS COMPLETE.
 HV6682'
 HV6682'IN AUGUST, 1977, THE CONSTRUCTION OF THE NEW ROAD WAS FOUND NEARLY
 HV6682'COMPLETED.  THE STATION SUB-SURFACE DISK WAS FOUND 3 FEET UNDER
 HV6682'THE GROUND AND IN THE EDGE OF THE ROAD.  REFERENCE MARK THREE
 HV6682'WAS FOUND IN GOOD CONDITION ALONG WITH REFERENCE POINT A.  NO
 HV6682'OTHER OF THE REFERENCE POINTS WERE FOUND.  THE DIRECTION BETWEEN
 HV6682'REFERENCE MARK THREE AND POINT A WAS FOUND TO BE WITHIN CLOSE
 HV6682'AGREEMENT WITH THE 1973 OBSERVATION.  THE DISTANCE TO BOTH
 HV6682'OBJECTS AGREED WITH THE 1973 DISTANCES.
 HV6682'
 HV6682'DUE TO THE STATION BEING NEAR THE ROAD AND NOW PLANS SHOW FOR A
 HV6682'RUN-OFF RAMP BEING BUILT, A NEW STATION CHASE 2 WAS ESTABLISHED.
 HV6682'IT WAS NOT POSSIBLE TO DETERMINE A SAFE LOCATION IN 1973 TO
 HV6682'MOVE THE STATION.
 HV6682'
 HV6682'A COMPLETE NEW DESCRIPTION OF THIS STATION FOLLOWS.
 HV6682'
 HV6682'THE STATION IS LOCATED 19 MILES NORTHWEST OF POINT LOOKOUT, 2-3/4
 HV6682'MILES NORTHWEST OF LEXINGTON PARK, 1-1/4 MILES SOUTHEAST OF
 HV6682'CALIFORNIA AND ON ROAD RIGHT-OF-WAY.

 HV6682'OF STATE HIGHWAY 235, 22.3 FEET SOUTH OF A WITNESS POST, AND 1.5
 HV6682'FEET SOUTHWEST OF THE NORTHEAST CURB OF STATE HIGHWAY 235.
 HV6682'
 HV6682'REFERENCE MARK THREE IS A STANDARD DISK STAMPED CHASE 1942 NO 3
 HV6682'1973 SET IN THE TOP OF A 10-INCH ROUND CONCRETE MONUMENT WHICH
 HV6682'PROJECTS 3-INCHES.  IT IS 150 FEET NORTHEAST OF THE CENTER OF THE
 HV6682'NORTHBOUND LANE OF STATE HIGHWAY 235, 117 FEET NORTH-NORTHEAST
 HV6682'OF THE WITNESS POST, 108 FEET EAST-NORTHEAST OF THE POWERLINE

 HV0819
 HV0819.The horizontal coordinates are valid at the epoch date displayed above
 HV0819.which is a decimal equivalence of Year/Month/Day.
 HV0819
 HV0819.The orthometric height was determined by differential leveling and
 HV0819.adjusted in June 1991.
 HV0819
 HV0819.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV0819
 HV0819.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV0819
 HV0819.The ellipsoidal height was determined by GPS observations
 HV0819.and is referenced to NAD 83.
 HV0819
 HV0819.The dynamic height is computed by dividing the NAVD 88
 HV0819.geopotential number by the normal gravity value computed on the

 JV4826.The horizontal coordinates were established by GPS observations
 JV4826.and adjusted by the National Geodetic Survey in February 2007.
 JV4826
 JV4826.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV4826.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV4826
 JV4826.The horizontal coordinates are valid at the epoch date displayed above
 JV4826.which is a decimal equivalence of Year/Month/Day.
 JV4826
 JV4826.The orthometric height was determined by differential leveling and
 JV4826.adjusted in June 1991.
 JV4826
 JV4826.WARNING-Repeat measurements at this control monument indicate possible
 JV4826.vertical movement.
 JV4826
 JV4826.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV4826
 JV4826.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV4826
 JV4826.The ellipsoidal height was determined by GPS observations
 JV4826.and is referenced to NAD 83.
 JV4826
 JV4826.The dynamic height is computed by dividing the NAVD 88
 JV4826.geopotential number by the normal gravity value computed on the
 JV4826.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV4826.degrees latitude (g = 980.6199 gals.).

 JV2273.The horizontal coordinates were established by GPS observations
 JV2273.and adjusted by the National Geodetic Survey in February 2007.
 JV2273
 JV2273.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV2273.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV2273
 JV2273.The horizontal coordinates are valid at the epoch date displayed above
 JV2273.which is a decimal equivalence of Year/Month/Day.
 JV2273
 JV2273.The orthometric height was determined by differential leveling and
 JV2273.adjusted in June 1991.
 JV2273
 JV2273.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV2273
 JV2273.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV2273
 JV2273.The ellipsoidal height was determined by GPS observations
 JV2273.and is referenced to NAD 83.
 JV2273
 JV2273.The dynamic height is computed by dividing the NAVD 88
 JV2273.geopotential number by the normal gravity value computed on the
 JV2273.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV2273.degrees latitude (g = 980.6199 gals.).
 JV2273
 JV2273.The modeled gravity was interpolated from observed gravity values.
 JV2273
 JV2273. The following values were computed from the NAD 83(2007) position.

 AJ8025.The horizontal coordinates were established by GPS observations
 AJ8025.and adjusted by the National Geodetic Survey in February 2007.
 AJ8025
 AJ8025.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 AJ8025.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 AJ8025
 AJ8025.The horizontal coordinates are valid at the epoch date displayed above
 AJ8025.which is a decimal equivalence of Year/Month/Day.
 AJ8025
 AJ8025.The orthometric height was determined by differential leveling and
 AJ8025.adjusted in November 2003.
 AJ8025
 AJ8025.No vertical observational check was made to the station.
 AJ8025
 AJ8025.Photographs are available for this station.
 AJ8025
 AJ8025.The X, Y, and Z were computed from the position and the ellipsoidal ht.

 HV7048
 HV7048'DESCRIBED BY COAST AND GEODETIC SURVEY 1929 (FLP)
 HV7048'STATION IS ON THE N SHORE OF THE POTOMAC RIVER, ON COBB ISLAND
 HV7048'NEAR THE WICOMICO RIVER.  STATION IS ABOUT 780 YARDS WNW OF COBB
 HV7048'POINT, 12 FEET FROM THE HIGHWATER LINE, AND 42 FEET FROM A BLUFF
 HV7048'THAT RISES TO A HEIGHT OF 8 FEET.  THE STATION IS LOCATED ON SANDY
 HV7048'SOIL, GROWN OVER BY TALL MARSH GRASS.  JUST S OF THE STATION THERE
 HV7048'ARE SEVERAL CLUMPS OF BUSHES.  BACK OF THE STATION, ALONG THE
 HV7048'BLUFF, AND JUST IN FRONT OF THE BLUFF, THERE IS A FAIRLY HEAVY
 HV7048'GROWTH OF SECOND-GROWTH PINE TREES.  THE STATION IS ABOUT 80 YARDS
 HV7048'ESE OF THE POINT WHERE THE BLUFF EXTENDS DOWN TO THE HIGH-WATER
 HV7048'LINE. DUE TO THE FACT THAT THE STATION IS LOCATED ON SANDY SOIL,
 HV7048'THERE WAS SET AN ESPECIALLY HEAVY MARK.
 HV7048'
 HV7048'THE STATION IS MARKED, AS DESCRIBED, WITH A U.S.C. AND G.S.
 HV7048'STANDARD DISK SET IN AN IRREGULAR MASS OF CONCRETE AS FOLLOWS--18
 HV7048'INCHES SQUARE ON TOP TO A DEPTH OF 4 INCHES, THEN APPROXIMATELY 2
 HV7048'FEET IN DIAMETER TO A DEPTH OF ABOUT 30 INCHES, AND BELLED ON THE
 HV7048'BOTTOM. THE MARK EXTENDS ABOUT 2 INCHES ABOVE THE SURFACE.
 HV7048'
 HV7048'REFERENCE MARK NO. 1 IS MARKED, AS DESCRIBED BY A STANDARD DISK,
 HV7048'SET IN AN IRREGULAR MASS OF CONCRETE, AS FOLLOWS--6 INCHES SQUARE
 HV7048'ON THE TOP, TO A DEPTH OF 4 INCHES, THENCE APPROXIMATELY
 HV7048'CYLINDRICAL AND 12 INCHES IN DIAMETER TO A DEPTH OF ABOUT 30
 HV7048'INCHES, AND BELLED AT THE BOTTOM.  IT IS SET ON TOP OF THE BLUFF,
 HV7048'4 FEET FROM THE FACE, AND ON THE LEFT OF THE FOOTPATH THAT RUNS
 HV7048'ALONG THE FACE OF THE BLUFF.  IT IS SET IN HEAVY, WELL COMPACTED
 HV7048'CLAY SOIL, AND IS SET SO THAT THE STATION, THE REFERENCE MARK, AND
 HV7048'THE NW CORNER OF THE HOUSE JUST TO THE BACK OF THE REFERENCE MARK
 HV7048'ARE IN RANGE.
 HV7048'
 HV7048'REFERENCE MARK NO. 2 IS SET ON TOP OF THE BLUFF, AND 6 FEET BACK
 HV7048'FROM THE FACE OF THE BLUFF, MARKED, AS DESCRIBED BY A STANDARD
 HV7048'REFERENCE MARK DISK AND SET IN THE SAME MANNER AS REFERENCE MARK
 HV7048'NO. 1.
 HV7048'
 HV7048'REFERENCE MARK NO. 1 IS STENCILED COBB NO. 1 1929, AND NO. 2 IS
 HV7048'STENCILED COBB NO. 2 1929.
 HV7048'
 HV7048'DISTANCES TO REFERENCE MARKS ARE MEASURED HORIZONTALLY.  BOTH
 HV7048'REFERENCE MARKS ARE APPROXIMATELY 8-1/2 FEET HIGHER THAN THE
 HV7048'STATION MARK.
 HV7048'
 HV7048'HEIGHT OF SIGNAL ABOVE STATION MARK - 4.0 METERS.

 HV7048'THE STATION WAS RECOVERED ACCORDING TO THE ORIGINAL DESCRIPTION.
 HV7048'THE DESCRIPTION IS ADEQUATE, EXCEPT FOR THE FOLLOWING FACTS.
 HV7048'
 HV7048'TWO NEW HOUSES HAVE BEEN BUILT BETWEEN REFERENCE MARKS NO. 1 AND
 HV7048'2, SO THAT REFERENCE MARK NO. 2 IS NOW 7 YARDS SXE OF THE SE
 HV7048'CORNER OF THE MOST EASTERLY HOUSE ON THE ISLAND.  THE DIRT HAS
 HV7048'BEEN WASHED AROUND THE MARKS SO THAT BOTH REFERENCE MARKS NO. 1
 HV7048'AND 2 ARE NOW FLUSH WITH THE GROUND.

 JV6331.The orthometric height was determined by differential leveling and
 JV6331.adjusted in June 1991.
 JV6331
 JV6331.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6331
 JV6331.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6331
 JV6331.The ellipsoidal height was determined by GPS observations

 JV6323.The horizontal coordinates were established by GPS observations
 JV6323.and adjusted by the National Geodetic Survey in February 2007.
 JV6323
 JV6323.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6323.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6323
 JV6323.The horizontal coordinates are valid at the epoch date displayed above
 JV6323.which is a decimal equivalence of Year/Month/Day.
 JV6323
 JV6323.The orthometric height was determined by differential leveling and
 JV6323.adjusted in June 1991.
 JV6323
 JV6323.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6323
 JV6323.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6323
 JV6323.The ellipsoidal height was determined by GPS observations
 JV6323.and is referenced to NAD 83.
 JV6323
 JV6323.The dynamic height is computed by dividing the NAVD 88
 JV6323.geopotential number by the normal gravity value computed on the
 JV6323.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6323.degrees latitude (g = 980.6199 gals.).
 JV6323
 JV6323.The modeled gravity was interpolated from observed gravity values.

 JV6329.The horizontal coordinates were established by GPS observations
 JV6329.and adjusted by the National Geodetic Survey in February 2007.
 JV6329
 JV6329.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6329.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6329
 JV6329.The horizontal coordinates are valid at the epoch date displayed above
 JV6329.which is a decimal equivalence of Year/Month/Day.
 JV6329
 JV6329.The orthometric height was determined by differential leveling and
 JV6329.adjusted in June 1991.
 JV6329
 JV6329.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6329
 JV6329.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6329
 JV6329.The ellipsoidal height was determined by GPS observations
 JV6329.and is referenced to NAD 83.
 JV6329
 JV6329.The dynamic height is computed by dividing the NAVD 88
 JV6329.geopotential number by the normal gravity value computed on the
 JV6329.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6329.degrees latitude (g = 980.6199 gals.).
 JV6329

 JV6027'THE DIRECTIONS FROM REISTERTOWN ARE EASILY FOLLOWED UP TO THE
 JV6027'POINT OF TAKING THE WOODS ROAD BETWEEN THE FORK WHICH IS NOW PRETTY
 JV6027'WELL WASHED IN PLACES AND GROWN OVER WITH SCRUBBY BRUSH.  AN
 JV6027'EASIER WAY TO FIND THE STATION NOW IS TO TAKE THE RIGHT FORK A
 JV6027'FEW HUNDRED FEET TO THE RIGHT-OF-WAY OF THE HIGH VOLTAGE
 JV6027'TRANSMISSION LINE.  ENTER A WINDING ROAD TO THE LEFT AND
 JV6027'REFERENCE MARK NO.2 WILL BE FOUND 75 YARDS S OF TOWER
 JV6027'NO.217, NUMBER STENCILED ON RIGHT HAND LEG LOOKING ALONG THE
 JV6027'AXIS RIGHT-OF-WAY.  GUIDED BY THE ARROW THE STATION IS EASILY
 JV6027'FOUND IN A GROVE OF SCRUB OAK.  THE TWO OTHER REFERENCE MARKS ALSO
 JV6027'ARE EASILY FOUND.  AT THE PRESENT TIME NOTHING IS VISIBLE
 JV6027'FROM THE GROUND, BUT AS SOON AS THE LEAVES FALL AT LEAST ONE
 JV6027'TRANSMISSION TOWER CAN BE SIGHTED ON, AND FROM THAT IT
 JV6027'WILL BE POSSIBLE TO EXTEND A CONTROL SURVEY OUT TO A POINT
 JV6027'FROM WHICH DISTANT OBJECTS MAY BE SEEN.  IT WOULD SEEM WISE,
 JV6027'HOWEVER, TO CHAIN ACCURATELY THE HORIZONTAL DISTANCE FROM
 JV6027'THE STATION TO REFERENCE MARK NO.2 BECAUSE SINCE THIS
 JV6027'MARKER IS ON THE RIGHT-OF-WAY IT IS ASSURED OF NOT
 JV6027'BECOMING OBSCURED BY BUSHES AND OTHER GROWTH.  THESE
 JV6027'RIGHTS-OF-WAY ARE ALWAYS KEPT CLEAR AND SO A FIXED POINT

 JV6651.The horizontal coordinates were established by GPS observations
 JV6651.and adjusted by the National Geodetic Survey in February 2007.
 JV6651
 JV6651.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6651.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6651
 JV6651.The horizontal coordinates are valid at the epoch date displayed above
 JV6651.which is a decimal equivalence of Year/Month/Day.
 JV6651
 JV6651.The orthometric height was determined by differential leveling and
 JV6651.adjusted in July 2002.
 JV6651
 JV6651.No vertical observational check was made to the station.
 JV6651
 JV6651.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6651
 JV6651.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6651
 JV6651.The ellipsoidal height was determined by GPS observations
 JV6651.and is referenced to NAD 83.
 JV6651
 JV6651.The dynamic height is computed by dividing the NAVD 88
 JV6651.geopotential number by the normal gravity value computed on the
 JV6651.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6651.degrees latitude (g = 980.6199 gals.).

 HV7083'STATION IS ON THE N SHORE OF THE POTOMAC RIVER, VICINITY OF KETTLE
 HV7083'BOTTOM SHOALS, AND NEAR THE NW END OF THE SHOALS.  ON SWAN POINT,
 HV7083'1-3/4 MILES, NAUTICAL, SSW FROM THE ENTRANCE TO CUCKOLD CREEK.
 HV7083'THE STATION IS LOCATED ON A BLUFF THAT IS ABOUT 6-1/2 FEET HIGH,
 HV7083'AND WITH ITS FACE AT THE HIGH-WATER LINE.  STATION IS 23 FEET FROM
 HV7083'THE FACE OF THIS BLUFF, AND 55 FEET FROM THE EXTREME SW POINT OF
 HV7083'THE BLUFF.  STATION IS 10 FEET N OF A RIDGE THAT RUNS
 HV7083'APPROXIMATELY E AND W ALONG THE TOP OF THE BLUFF.  THERE IS A
 HV7083'TELEPHONE LINE RUNNING ALONG THE SHORE, AND IT CHANGES DIRECTION
 HV7083'FROM APPROXIMATELY N AND S TO E AND W AT THE STATION. THE STATION
 HV7083'IS APPROXIMATELY 25 YARDS NORMAL TO THE CENTER OF THE SHORT
 HV7083'SECTION THAT JOINS THE TANGENTS.  THE VEGETATION IN THE VICINITY
 HV7083'OF THE STATION IS GRASS ONLY, THE NEAREST TREES BEING A
 HV7083'CONSIDERABLE DISTANCE INSHORE FROM THE STATION.  THE STATION IS
 HV7083'LOCATED IN A HEAVY, WELL COMPACTED CLAY SOIL.
 HV7083'
 HV7083'THE STATION SUB-SURFACE MARK IS MARKED, AS DESCRIBED IN NOTE 7A,
 HV7083'BY A U.S.C. AND G.S. STANDARD DISK SET IN AN IRREGULAR MASS OF
 HV7083'CONCRETE, APPROXIMATELY CYLINDRICAL IN SHAPE, BEING ABOUT 8 INCHES
 HV7083'DEEP, AND 13 INCHES IN DIAMETER, THE SURFACE OF THE MARK BEING
 HV7083'APPROXIMATELY 3 FEET BELOW THE SURFACE OF THE GROUND.  ABOVE THE
 HV7083'SUB-SURFACE MARK, THERE IS A LAYER OF SAND APPROXIMATELY 6 INCHES
 HV7083'THICK.  THE SURFACE MARK IS MARKED, AS DESCRIBED IN NOTE 1C, BY A
 HV7083'U.S.C. AND G.S. STANDARD DISK SET IN AN IRREGULAR MASS OF
 HV7083'CONCRETE AS FOLLOWS--9 INCHES SQUARE ON TOP, THENCE IN THE SHAPE
 HV7083'OF A PYRAMID TO A DEPTH OF 4 INCHES, THENCE ROUGHLY CYLINDRICAL
 HV7083'AND ABOUT 15 INCHES IN DIAMETER TO A DEPTH OF 27 INCHES.  IT
 HV7083'PROJECTS ABOUT 2 INCHES ABOVE THE SURFACE OF THE GROUND.  BOTH THE
 HV7083'SUB-SURFACE AND THE SURFACE MARKS WERE STENCILED CUCKOLD 1929.
 HV7083'
 HV7083'REFERENCE MARK NO.1 IS MARKED, AS DESCRIBED IN NOTE 11C, BY A
 HV7083'U.S.C. AND G.S. STANDARD DISK, SET IN AN IRREGULAR MASS OF

 JV5608'A TRIANGULATION STATION DISK STAMPED CURB 2 1971 WAS FOUND IN THE
 JV5608'WEST SIDEWALK OF THE HANOVER STREET BRIDGE.  NO DATA HAS EVER BEEN
 JV5608'SENT INTO THE OFFICE ON THIS STATION AND AN ATTEMPT WAS MADE AT
 JV5608'THIS DATE TO DETERMINE IF THE DISK FOUND HAD BEEN SET IN THE SAME
 JV5608'HORIZONTAL POSITION AS THE OLD STATION CURB 1934.  IT IS BELIEVED
 JV5608'THAT STATION CURB 1934 WAS ORIGINALLY SET IN THE EAST CURB OF THE
 JV5608'BRIDGE AND WAS DESTROYED BY CONSTRUCTION.  IT IS ALSO BELIEVED
 JV5608'THAT THE CONSTRUCTION COMPANY SET A NEW DISK IN THE WEST CURB OF THE
 JV5608'BRIDGE AFTER THE CONSTRUCTION WAS COMPLETED AND THAT WAS THE
 JV5608'DISK FOUND AT THIS DATE.  THE ABOVE THEORY WAS VERIFIED THROUGH
 JV5608'OBSERVATIONS.  THE AZIMUTHS TO SEVERAL INTERSECTION STATIONS WERE
 JV5608'OBSERVED AND THE RESULTS SHOWED THE NEW DISK TO BE IN BEARING

 JW1512.The horizontal coordinates were established by GPS observations
 JW1512.and adjusted by the National Geodetic Survey in February 2007.
 JW1512
 JW1512.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JW1512.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JW1512
 JW1512.The horizontal coordinates are valid at the epoch date displayed above
 JW1512.which is a decimal equivalence of Year/Month/Day.
 JW1512
 JW1512.The orthometric height was determined by differential leveling and
 JW1512.adjusted in June 1991.
 JW1512
 JW1512.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JW1512
 JW1512.The Laplace correction was computed from DEFLEC09 derived deflections.
 JW1512
 JW1512.The ellipsoidal height was determined by GPS observations
 JW1512.and is referenced to NAD 83.
 JW1512
 JW1512.The dynamic height is computed by dividing the NAVD 88
 JW1512.geopotential number by the normal gravity value computed on the
 JW1512.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JW1512.degrees latitude (g = 980.6199 gals.).
 JW1512
 JW1512.The modeled gravity was interpolated from observed gravity values.

 JV6267
 JV6267.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6267.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6267
 JV6267.The horizontal coordinates are valid at the epoch date displayed above
 JV6267.which is a decimal equivalence of Year/Month/Day.
 JV6267
 JV6267.The orthometric height was determined by differential leveling and
 JV6267.adjusted in June 1991.
 JV6267
 JV6267.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6267
 JV6267.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6267
 JV6267.The ellipsoidal height was determined by GPS observations
 JV6267.and is referenced to NAD 83.
 JV6267
 JV6267.The dynamic height is computed by dividing the NAVD 88
 JV6267.geopotential number by the normal gravity value computed on the
 JV6267.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6267.degrees latitude (g = 980.6199 gals.).

 JW1205.The horizontal coordinates were established by GPS observations
 JW1205.and adjusted by the National Geodetic Survey in February 2007.
 JW1205
 JW1205.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JW1205.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JW1205
 JW1205.The horizontal coordinates are valid at the epoch date displayed above
 JW1205.which is a decimal equivalence of Year/Month/Day.
 JW1205
 JW1205.The orthometric height was determined by differential leveling and
 JW1205.adjusted in June 1991.
 JW1205
 JW1205.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JW1205
 JW1205.The Laplace correction was computed from DEFLEC09 derived deflections.
 JW1205
 JW1205.The ellipsoidal height was determined by GPS observations
 JW1205.and is referenced to NAD 83.
 JW1205
 JW1205.The dynamic height is computed by dividing the NAVD 88
 JW1205.geopotential number by the normal gravity value computed on the
 JW1205.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JW1205.degrees latitude (g = 980.6199 gals.).
 JW1205
 JW1205.The modeled gravity was interpolated from observed gravity values.
 JW1205
 JW1205. The following values were computed from the NAD 83(2007) position.

 HV6545
 HV6545'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1942 (WDP)
 HV6545'THIS STATION WAS THOROUGHLY SEARCHED FOR BY TWO MEN FOR ONE HOUR,
 HV6545'BUT NO TRACE OF IT COULD BE FOUND.  A FISHERMAN REPORTED THE POINT
 HV6545'TO BE WASHED OVER MANY TIMES, AND THE POINT IS NOW THICKLY COVERED
 HV6545'WITH MARSH GRASS AND SMALL BUSHES.  IT IS RECOMMENDED THAT THIS
 HV6545'STATION BE CLASSIFIED AS LOST.

 JV6326.The horizontal coordinates were established by GPS observations
 JV6326.and adjusted by the National Geodetic Survey in February 2007.
 JV6326
 JV6326.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6326.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6326
 JV6326.The horizontal coordinates are valid at the epoch date displayed above
 JV6326.which is a decimal equivalence of Year/Month/Day.
 JV6326
 JV6326.The orthometric height was determined by differential leveling and
 JV6326.adjusted in June 1991.
 JV6326
 JV6326.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6326
 JV6326.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6326
 JV6326.The ellipsoidal height was determined by GPS observations
 JV6326.and is referenced to NAD 83.
 JV6326
 JV6326.The dynamic height is computed by dividing the NAVD 88
 JV6326.geopotential number by the normal gravity value computed on the
 JV6326.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6326.degrees latitude (g = 980.6199 gals.).

 HU0431.The horizontal coordinates were established by GPS observations
 HU0431.and adjusted by the National Geodetic Survey in February 2007.
 HU0431
 HU0431.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HU0431.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HU0431
 HU0431.The horizontal coordinates are valid at the epoch date displayed above
 HU0431.which is a decimal equivalence of Year/Month/Day.
 HU0431
 HU0431.No horizontal observational check was made to the station.
 HU0431.
 HU0431.The orthometric height was determined by differential leveling and
 HU0431.adjusted in June 1991.
 HU0431
 HU0431.Photographs are available for this station.
 HU0431
 HU0431.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HU0431
 HU0431.The Laplace correction was computed from DEFLEC09 derived deflections.
 HU0431
 HU0431.The ellipsoidal height was determined by GPS observations
 HU0431.and is referenced to NAD 83.
 HU0431
 HU0431.The dynamic height is computed by dividing the NAVD 88
 HU0431.geopotential number by the normal gravity value computed on the

 HV0047.The horizontal coordinates were established by GPS observations
 HV0047.and adjusted by the National Geodetic Survey in February 2007.
 HV0047
 HV0047.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV0047.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV0047
 HV0047.The horizontal coordinates are valid at the epoch date displayed above
 HV0047.which is a decimal equivalence of Year/Month/Day.
 HV0047
 HV0047.The orthometric height was determined by differential leveling and
 HV0047.adjusted in September 2004.
 HV0047
 HV0047.No vertical observational check was made to the station.
 HV0047
 HV0047.Photographs are available for this station.
 HV0047
 HV0047.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV0047
 HV0047.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV0047
 HV0047.The ellipsoidal height was determined by GPS observations
 HV0047.and is referenced to NAD 83.
 HV0047
 HV0047.The dynamic height is computed by dividing the NAVD 88
 HV0047.geopotential number by the normal gravity value computed on the
 HV0047.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV0047.degrees latitude (g = 980.6199 gals.).
 HV0047
 HV0047.The modeled gravity was interpolated from observed gravity values.

 HV8269.This mark is at Easton/newnam Field Airport (ESN)
 HV8269
 HV8269.The horizontal coordinates were established by GPS observations
 HV8269.and adjusted by the National Geodetic Survey in February 2007.
 HV8269
 HV8269.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV8269.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV8269
 HV8269.The horizontal coordinates are valid at the epoch date displayed above
 HV8269.which is a decimal equivalence of Year/Month/Day.
 HV8269
 HV8269.The orthometric height was determined by GPS observations and a
 HV8269.high-resolution geoid model.
 HV8269
 HV8269.GPS derived orthometric heights for airport stations designated as
 HV8269.PACS or SACS are published to 2 decimal places.  This maintains
 HV8269.centimeter relative accuracy between the PACS and SACS.  It does
 HV8269.not indicate centimeter accuracy relative to other marks which are
 HV8269.part of the NAVD 88 network.
 HV8269
 HV8269.Photographs are available for this station.
 HV8269
 HV8269.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV8269
 HV8269.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV8269
 HV8269.The ellipsoidal height was determined by GPS observations
 HV8269.and is referenced to NAD 83.
 HV8269
 HV8269. The following values were computed from the NAD 83(2007) position.

 JV6473
 JV6473.The horizontal coordinates were established by GPS observations
 JV6473.and adjusted by the National Geodetic Survey in February 2007.
 JV6473
 JV6473.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6473.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6473
 JV6473.The horizontal coordinates are valid at the epoch date displayed above
 JV6473.which is a decimal equivalence of Year/Month/Day.
 JV6473
 JV6473.The orthometric height was determined by differential leveling
 JV6473.and adjusted in August 1994.
 JV6473
 JV6473.The height was determined by precise leveling from only one NSRS
 JV6473.bench mark.  This was not adequate "tie leveling" to NSRS and was
 JV6473.allowed ONLY to validate the GPS-derived height.
 JV6473
 JV6473.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6473
 JV6473.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6473
 JV6473.The ellipsoidal height was determined by GPS observations
 JV6473.and is referenced to NAD 83.
 JV6473
 JV6473.The dynamic height is computed by dividing the NAVD 88
 JV6473.geopotential number by the normal gravity value computed on the
 JV6473.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6473.degrees latitude (g = 980.6199 gals.).
 JV6473
 JV6473.The modeled gravity was interpolated from observed gravity values.
 JV6473
 JV6473. The following values were computed from the NAD 83(2007) position.

 JV6328.and adjusted by the National Geodetic Survey in February 2007.
 JV6328
 JV6328.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6328.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6328
 JV6328.The horizontal coordinates are valid at the epoch date displayed above
 JV6328.which is a decimal equivalence of Year/Month/Day.
 JV6328
 JV6328.The orthometric height was determined by differential leveling and
 JV6328.adjusted in June 1991.
 JV6328
 JV6328.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6328
 JV6328.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6328
 JV6328.The ellipsoidal height was determined by GPS observations
 JV6328.and is referenced to NAD 83.
 JV6328
 JV6328.The dynamic height is computed by dividing the NAVD 88
 JV6328.geopotential number by the normal gravity value computed on the

 HV8927.The horizontal coordinates were established by GPS observations
 HV8927.and adjusted by the National Geodetic Survey in February 2007.
 HV8927
 HV8927.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV8927.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV8927
 HV8927.The horizontal coordinates are valid at the epoch date displayed above
 HV8927.which is a decimal equivalence of Year/Month/Day.
 HV8927
 HV8927.The orthometric height was determined by differential leveling and
 HV8927.adjusted in August 1994.
 HV8927
 HV8927.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV8927
 HV8927.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV8927
 HV8927.The ellipsoidal height was determined by GPS observations
 HV8927.and is referenced to NAD 83.
 HV8927
 HV8927.The dynamic height is computed by dividing the NAVD 88
 HV8927.geopotential number by the normal gravity value computed on the
 HV8927.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV8927.degrees latitude (g = 980.6199 gals.).
 HV8927
 HV8927.The modeled gravity was interpolated from observed gravity values.

 JV0947
 JV0947'DESCRIBED BY COAST AND GEODETIC SURVEY 1933 (RDH)
 JV0947'STATION IS ABOUT 5 MILES SE OF BALTIMORE BUSINESS SECTION, 1 MILE
 JV0947'SE OF BROOKLYN, ON THE W SIDE OF CURTIS BAY AND CURTIS CREEK, ON
 JV0947'PROPERTY OWNED BY THE BALTIMORE WATER WORKS COMMISSION.  IT IS
 JV0947'ON TOP OF THE HILL IN SOUTH BALTIMORE ON WHICH IS LOCATED A LARGE
 JV0947'BRICK RESERVOIR AND A METAL STANDPIPE, ABOUT 300 YARDS W OF
 JV0947'PENINGTON STREET ON LINE WITH THE CENTER LINE OF FILBERT
 JV0947'STREET.  IT IS IN AN UNCULTIVATED FIELD, 79.1 FEET NW OF THE NW
 JV0947'SIDE OF THE RESERVOIR, 50 FEET WSW OF A CURVE IN THE DIRT
 JV0947'ROAD, AND 23.5 FEET WSW OF A 2-INCH CAST-IRON PIPE THAT
 JV0947'PROTRUDES FROM THE GROUND AT AN ANGLE ABOUT 1 FOOT.  THE
 JV0947'STATION MARK IS ABOUT 4 INCHES ABOVE THE GROUND.
 JV0947'
 JV0947'PROSPECT IS A STATION OF THE BALTIMORE PLANS AND SURVEYS, AND
 JV0947'CONSISTS OF A CAST-IRON PIPE WITH A CAP MARKED NO. 128 FLUSH WITH
 JV0947'THE GROUND.  IT IS AN UNCULTIVATED FIELD, NNE OF THE STATION,
 JV0947'ABOUT 75 YARDS E (W) OF THE DIRT ROAD.  USED FOR AN AZIMUTH MARK.
 JV0947'
 JV0947'SURFACE, UNDERGROUND AND REFERENCE MARKS ARE STANDARD BRONZE
 JV0947'DISKS SET IN CONCRETE.
 JV0947'
 JV0947'REFERENCE MARK NO.1 IS N OF THE STATION, 43 YARDS N OF THE CURVE
 JV0947'IN THE ROAD, AND 3 YARDS W OF THE CENTER LINE OF THE DIRT ROAD.
 JV0947'
 JV0947'REFERENCE MARK NO.2 IS SE OF THE STATION IN THE FOOTING OF THE
 JV0947'RESERVOIR ON THE W SIDE, MIDWAY BETWEEN TWO ARTIFICIAL WINDOWS.
 JV0947'
 JV0947'THE OBJECTS LISTED ABOVE ARE ALL VISIBLE FROM THE GROUND.  THE
 JV0947'WOODEN TANK IS THE TANK OF THE U.S. ARMY ORDINANCE PLANT.  THE
 JV0947'SPIRE, WITH THE RED LIGHT, IS IN THE CITY OF BALTIMORE, AND IS ON
 JV0947'THE BROMO SELTZER BUILDING.
 JV0947'
 JV0947'FOUR POSITIONS OF THE CIRCLE WERE OBSERVED ON THIS RED LIGHT,
 JV0947'THE AVIATION BEACON, AND PROSPECT.  THE STACK IS VISIBLE STRAIGHT
 JV0947'DOWN FILBERT STREET.
 JV0947'
 JV0947'HEIGHT OF LIGHT ABOVE STATION MARK 30 METERS.

 JV0947
 JV0947'RECOVERY NOTE BY PENNSYLVANIA WATER AND POWER COMPANY 1940
 JV0947'FOUND STATION WITHOUT DIFFICULTY FROM MIMEO. DIRECTIONS.  ALTHOUGH,
 JV0947'WEEDS HAVE SINCE OVERGROWN THE MONUMENT.  THE EASIEST WAY IS TO
 JV0947'LOOK FIRST FOR REFERENCE MARK NO.2 ON FOOTING OF TANK, AND THEN
 JV0947'FOLLOW THE ARROW 82.05 FEET.  COULD NOT FIND PROSPECT WITHOUT
 JV0947'SETTING UP INSTRUMENT AND HAVING HELP TO LINE ME UP.  AS, FIELD
 JV0947'HAS BECOME BADLY OVERGROWN WITH BUSHES.  SUGGEST THAT IN THE
 JV0947'FUTURE REFERENCE MARKS (LIKE NO.2) BE SET OUT A LITTLE FARTHER
 JV0947'FROM VERTICAL WALL IN ORDER THAT AN INSTRUMENT CAN BE SET UP
 JV0947'OVER THEM.  THE RED LIGHT ON THE BROMO SELTZER BUILDING HAS
 JV0947'SINCE BEEN REMOVED.  A PROMINENT OBJECT VISIBLE FROM THE GROUND
 JV0947'AT THE STATION IS THE FLAGPOLE AT FORT MC HENRY.

 JV0947
 JV0947'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1940 (RJS)
 JV0947'STATION AND REFERENCE MARKS WERE RECOVERED AS DESCRIBED AND IN
 JV0947'GOOD CONDITION.
 JV0947'
 JV0947'THE AZIMUTH MARK (STATION PROSPECT) WAS NOT RECOVERED.  BUT, IT
 JV0947'WAS NOT PROVEN TO BE LOST.

 JV0947
 JV0947'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1943 (CFM)
 JV0947'REFERENCE MARK NO. 1 WAS DESTROYED DURING EXCAVATIONS FOR A SEWER
 JV0947'FOR NEW HOUSES.  IT WAS NO LONGER VISIBLE FROM THE STATION, HOUSES
 JV0947'HAVING BEEN BUILT IN THE WAY.  A REFERENCE MARK NO. 3, NOT
 JV0947'DESCRIBED IN THE ORIGINAL DESCRIPTION, WAS EVIDENTLY SET FOR AN
 JV0947'AZIMUTH MARK AND NOT USED.  THIS MARK WAS REMOVED ALSO.
 JV0947'
 JV0947'THE STATION MARK IS NOT IN THE HOUSING PROJECT AREA AND IS
 JV0947'UNDISTURBED.  WITH BUILDING OF THE HOUSING PROJECT, WHICH IS OF
 JV0947'TEMPORARY CONSTRUCTION, THERE IS ONLY A VERY LIMITED OUTLOOK TO
 JV0947'ANY DISTANT OBJECTS EXCEPT EASTWARD ALONG FILBERT STREET.  THE
 JV0947'STACK OF THE PAN AMERICAN OIL IS OBSCURED BY AN ELECTRIC LIGHT
 JV0947'POLE.  REFERENCE MARK NO. 2 IS SET IN THE CONCRETE FOOTING OF A
 JV0947'LARGE BRICK RESERVOIR, THE CURTIS BAY RESERVOIR.
 JV0947'
 JV0947'MR. ROBERT SUTTON, WHO IS RUNNING THE PROPERTY SURVEY OBSERVED
 JV0947'ANGLES TO THREE NEARBY CORNERS OF THE PROJECT BOUNDARY, WHICH
 JV0947'TOGETHER WITH SOME CHAINED DISTANCES WILL TIE IN TWO OF
 JV0947'THEM.  AT PRESENT THESE ARE WOODEN HUBS BUT ARE TO BE REPLACED
 JV0947'WITH CONCRETE MONUMENTS IN WHICH I SHALL HAVE REFERENCE MARKS
 JV0947'PLACED.

 JV5442
 JV5442'DESCRIBED BY COAST AND GEODETIC SURVEY 1896
 JV5442'ABOUT 9 MILES NORTHEASTERLY FROM BALTIMORE, 300 FEET E OF THE OLD
 JV5442'HARFORD ROAD, 3/4 MILE W OF THE HARFORD TURNPIKE, ON CUB HILL, ON
 JV5442'THE OLD FINLAY FARM, NOW THE PROPERTY OF THEODORE FASTIE.  THE
 JV5442'NE CORNER OF AN OLD LOG HOUSE, FORMERLY A SCHOOLHOUSE BUT NOW A
 JV5442'BLACKSMITH SHOP, IS 253.71 FEET FROM THE STATION S 47
 JV5442'DEG 06 MIN E.  THE BEARING OF THE E GABLE OF STONE BARN ON THE
 JV5442'FASTIE PLACE IS N 9 DEG 28 MIN E.  AND A LARGE CHERRY TREE IS
 JV5442'126.85 FEET FROM THE STATION S 22 DEG 46 MIN E.  IN 1896
 JV5442'THE STATION WAS RE-MARKED AS FOLLOWS--A GLAZED DRAIN TILE, 4
 JV5442'INCHES IN DIAMETER AND 30 INCHES LONG, WAS SUNK IN THE
 JV5442'GROUND SO THAT ITS UPPER END WAS 3 FEET BELOW THE SURFACE OF
 JV5442'THE GROUND.  IT WAS SET IN CEMENT AND GRAVEL AND THE CENTER
 JV5442'OF THE STATION MARKED BY A 60D NAIL.  ABOVE THIS WAS PLACED
 JV5442'A CHESTNUT POST, ITS TOP EVEN WITH THE SURFACE OF THE GROUND,
 JV5442'WITH A 40D NAIL MARKING THE CENTER.

 JV5442
 JV5442'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1933 (ERM)
 JV5442'ONLY ONE MEASUREMENT NOW REMAINS, VIZ., THAT TO THE CORNER OF THE
 JV5442'OLD LOG BLACKSMITHS SHOP.  THE SURFACE MARK SET IN 1896 HAS LONG
 JV5442'SINCE GONE, THE FIELD BEING REGULARLY IN CULTIVATION.  THE PRESENT
 JV5442'OWNERS DO NOT KNOW THE LOCATION OF THE OLD STATION, AND DO NOT
 JV5442'ENCOURAGE ANY OPERATION TOWARDS THE RECOVERY OF IT UNLESS THEY
 JV5442'ARE PAID.  SOME EFFORT WAS MADE TO RECOVER THE STATION BY
 JV5442'PRODDING WITH STEEL RODS, BUT THE GROUND IS OF CLAY AND
 JV5442'FILLED WITH SMALL ROCKS.  SO IT APPEARS THAT THE ONLY WAY TO
 JV5442'RECOVER IT IS TO ESTABLISH A NEW ONE AND HAVE A DEFINITE
 JV5442'BEARING AND DISTANCE.

 JV5442'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1938 (CIA)
 JV5442'ALL REFERENCE POINTS EXCEPT THE BLACKSMITH SHOP ARE GONE.  SIGNS OF
 JV5442'THE RUINS OF THAT STILL REMAIN.  THE SURFACE MARK WAS GONE AND
 JV5442'THE UNDERGROUND MARK WHICH WAS RECOVERED WAS IN GOOD
 JV5442'CONDITION.  THE STATION WAS RECOVERED BY A MEASURED DISTANCE AND
 JV5442'DIRECTION FROM STATION FINLAY 2 (1934).  THE UNDERGROUND MARK IS
 JV5442'A GOOD 4 FEET BELOW THE SURFACE OF THE GROUND.  NO NEW SURFACE
 JV5442'MARK WAS ESTABLISHED BECAUSE OF THE NEW STATION FINLAY 2
 JV5442'(1934).  AN ACCURATE TIE WAS MADE TO THE LATTER STATION.

 DH8206'THIS MARK IS AT THE NORTHERLY SECTION OF A DIVIDED FOOT BRIDGE IN THE
 DH8206'BLACKWATER RIVER.  IT IS APPROXIMATELY A 20-MINUTE RIDE TO THE WEST BY
 DH8206'JOHN BOAT FROM THE BOAT RAMP AT THE  RT 335 BRIDGE. IT IS THE TOP
 DH8206'CENTER OF A STAINLESS STEEL ROD DRIVEN 60 FT TO REFUSAL  BETWEEN TWO
 DH8206'BOARDS IN THE CENTERLINE OF THE BRIDGE. THERE IS A 1-INCH PVC PIPE
 DH8206'AROUND  THE ROD. THE BRIDGE IS ROUGHLY 30 INCHES WIDE.
 DH8206' 
 DH8206'TO ARRANGE ACCESS, CONTACT BLACKWATER NATIONAL WILDLIFE REFUGE STAFF
 DH8206'AT 410-228-2692 AS  FAR IN ADVANCE AS POSSIBLE. A BOAT IS NEEDED TO
 DH8206'REACH THE MARK.
 DH8206' 
 DH8206'THE MARK IS 10.5 FT SOUTH (TOWARD MIDDLE OF RIVER) FROM THE GALVANIZED
 DH8206'PIPE ON THE WEST  SIDE OF THE BRIDGE THAT SUPPORTS THE USGS WATER
 DH8206'LEVEL GAGE, AND 3.5 FT NORTH TOWARD  THE SHORE FROM THE BOTTOM STEP OF
 DH8206'SEVERAL STEPS LEADING UP TO AN OBSERVATION  PLATFORM. IT PROJECTS
 DH8206'ABOUT 1 CM ABOVE THE SURROUNDING BOARDS. THIS LOCATION IS ABOUT  190
 DH8206'FT SOUTH OF THE SOUTHERLY LINE OF CATTAILS AT THE SHORE.
 DH8206' 
 DH8206'NO PROVISION COULD BE MADE TO ANCHOR THE ROD TO PREVENT HORIZONTAL
 DH8206'MOTION WITHOUT  MODIFYING THE BRIDGE. CONSEQUENTLY, THE ROD CAN MOVE
 DH8206'SLIGHTLY, MOSTLY TO THE SOUTH. TO  THE N, W AND E IT IS PRETTY WELL
 DH8206'CONSTRAINED BY THE BOARDS IN THE BRIDGE. A PIECE OF  HIGH-DENSITY FOAM
 DH8206'COULD BE INSERTED TO PREVENT SOUTHERLY MOTION.

 JV4827'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1967 (JCB)
 JV4827'STATION WAS SEARCHED FOR BUT NOT RECOVERED.  THE COUNTRY ROAD
 JV4827'REFERRED TO IN THE DESCRIPTION IS NO LONGER USED.  THE REFERENCE
 JV4827'MARKS HAD BEEN BULLDOZED OFF INTO THE OLD ROADBED AND THE DISKS
 JV4827'WERE RECLAIMED AT THIS TIME.  THE FENCE AND THE CEDAR TREE
 JV4827'REFERRED TO IN THE DESCRIPTION HAVE ALSO BEEN BULLDOZED OFF INTO
 JV4827'THE OLD ROADBED.  THE PROPERTY OWNER, MR. REEVES, STATED THAT
 JV4827'THE STATION MARK WAS NOT SET DEEP ENOUGH AND HAD BEEN PLOWED
 JV4827'UP.  EXTENSIVE PROBING IN THE CULTIVATED FIELD WAS TO NO
 JV4827'AVAIL.  A NEW HOME IS BEING CONSTRUCTED AT THE SITE OF THE
 JV4827'AZIMUTH MARK WHICH NECESSITATED THE RELOCATING OF SAME, SO THE

 JV6406.The horizontal coordinates were established by GPS observations
 JV6406.and adjusted by the National Geodetic Survey in February 2007.
 JV6406
 JV6406.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV6406.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV6406
 JV6406.The horizontal coordinates are valid at the epoch date displayed above
 JV6406.which is a decimal equivalence of Year/Month/Day.
 JV6406
 JV6406.The orthometric height was determined by differential leveling and
 JV6406.adjusted in June 1991.
 JV6406
 JV6406.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV6406
 JV6406.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV6406
 JV6406.The ellipsoidal height was determined by GPS observations
 JV6406.and is referenced to NAD 83.
 JV6406
 JV6406.The dynamic height is computed by dividing the NAVD 88
 JV6406.geopotential number by the normal gravity value computed on the
 JV6406.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV6406.degrees latitude (g = 980.6199 gals.).
 JV6406
 JV6406.The modeled gravity was interpolated from observed gravity values.

 JW1536.This mark is at Garrett County Airport (2G4)
 JW1536
 JW1536.The horizontal coordinates were established by GPS observations
 JW1536.and adjusted by the National Geodetic Survey in February 2007.
 JW1536
 JW1536.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JW1536.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JW1536
 JW1536.The horizontal coordinates are valid at the epoch date displayed above
 JW1536.which is a decimal equivalence of Year/Month/Day.
 JW1536
 JW1536.The orthometric height was determined by GPS observations and a
 JW1536.high-resolution geoid model.
 JW1536
 JW1536.GPS derived orthometric heights for airport stations designated as
 JW1536.PACS or SACS are published to 2 decimal places.  This maintains
 JW1536.centimeter relative accuracy between the PACS and SACS.  It does
 JW1536.not indicate centimeter accuracy relative to other marks which are
 JW1536.part of the NAVD 88 network.
 JW1536
 JW1536.Photographs are available for this station.
 JW1536
 JW1536.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JW1536
 JW1536.The Laplace correction was computed from DEFLEC09 derived deflections.
 JW1536
 JW1536.The ellipsoidal height was determined by GPS observations
 JW1536.and is referenced to NAD 83.
 JW1536
 JW1536. The following values were computed from the NAD 83(2007) position.

 AC7688
 AC7688.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 AC7688.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 AC7688
 AC7688.The horizontal coordinates are valid at the epoch date displayed above
 AC7688.which is a decimal equivalence of Year/Month/Day.
 AC7688
 AC7688.The orthometric height was determined by differential leveling and
 AC7688.adjusted in February 1998.
 AC7688
 AC7688.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AC7688
 AC7688.The Laplace correction was computed from DEFLEC09 derived deflections.
 AC7688
 AC7688.The ellipsoidal height was determined by GPS observations
 AC7688.and is referenced to NAD 83.
 AC7688
 AC7688.The dynamic height is computed by dividing the NAVD 88

 AE2444.The horizontal coordinates were established by GPS observations
 AE2444.and adjusted by the National Geodetic Survey in February 2007.
 AE2444
 AE2444.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 AE2444.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 AE2444
 AE2444.The horizontal coordinates are valid at the epoch date displayed above
 AE2444.which is a decimal equivalence of Year/Month/Day.
 AE2444
 AE2444.The orthometric height was determined by differential leveling and
 AE2444.adjusted in February 1998.
 AE2444
 AE2444.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AE2444
 AE2444.The Laplace correction was computed from DEFLEC09 derived deflections.
 AE2444
 AE2444.The ellipsoidal height was determined by GPS observations
 AE2444.and is referenced to NAD 83.
 AE2444
 AE2444.The dynamic height is computed by dividing the NAVD 88
 AE2444.geopotential number by the normal gravity value computed on the
 AE2444.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AE2444.degrees latitude (g = 980.6199 gals.).
 AE2444
 AE2444.The modeled gravity was interpolated from observed gravity values.
 AE2444
 AE2444. The following values were computed from the NAD 83(2007) position.

 AE2447.The horizontal coordinates were established by GPS observations
 AE2447.and adjusted by the National Geodetic Survey in February 2007.
 AE2447
 AE2447.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 AE2447.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 AE2447
 AE2447.The horizontal coordinates are valid at the epoch date displayed above
 AE2447.which is a decimal equivalence of Year/Month/Day.
 AE2447
 AE2447.The orthometric height was determined by differential leveling and
 AE2447.adjusted in February 1998.
 AE2447
 AE2447.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AE2447
 AE2447.The Laplace correction was computed from DEFLEC09 derived deflections.
 AE2447
 AE2447.The ellipsoidal height was determined by GPS observations
 AE2447.and is referenced to NAD 83.
 AE2447
 AE2447.The dynamic height is computed by dividing the NAVD 88
 AE2447.geopotential number by the normal gravity value computed on the
 AE2447.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AE2447.degrees latitude (g = 980.6199 gals.).
 AE2447
 AE2447.The modeled gravity was interpolated from observed gravity values.
 AE2447
 AE2447. The following values were computed from the NAD 83(2007) position.

 AB5608
 AB5608.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 AB5608.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 AB5608
 AB5608.The horizontal coordinates are valid at the epoch date displayed above
 AB5608.which is a decimal equivalence of Year/Month/Day.
 AB5608
 AB5608.The orthometric height was determined by differential leveling and
 AB5608.adjusted in September 2004.
 AB5608
 AB5608.Photographs are available for this station.
 AB5608
 AB5608.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AB5608
 AB5608.The Laplace correction was computed from DEFLEC09 derived deflections.
 AB5608
 AB5608.The ellipsoidal height was determined by GPS observations

 HV9185
 HV9185.The horizontal coordinates were established by GPS observations
 HV9185.and adjusted by the National Geodetic Survey in February 2007.
 HV9185
 HV9185.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV9185.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV9185
 HV9185.The horizontal coordinates are valid at the epoch date displayed above
 HV9185.which is a decimal equivalence of Year/Month/Day.
 HV9185
 HV9185.The orthometric height was determined by differential leveling and
 HV9185.adjusted in September 2004.
 HV9185
 HV9185.No vertical observational check was made to the station.
 HV9185
 HV9185.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV9185
 HV9185.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV9185
 HV9185.The ellipsoidal height was determined by GPS observations
 HV9185.and is referenced to NAD 83.
 HV9185
 HV9185.The dynamic height is computed by dividing the NAVD 88
 HV9185.geopotential number by the normal gravity value computed on the
 HV9185.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV9185.degrees latitude (g = 980.6199 gals.).
 HV9185
 HV9185.The modeled gravity was interpolated from observed gravity values.

 HU1579'
 HU1579'THE GENERAL TOPOGRAPHY OF THE BEACH IN THE VICINITY OF THE
 HU1579'STATION WAS GREATLY CHANGED BY THE AUGUST 23, 1933, STORM.  A
 HU1579'LOW FLAT BEACH EXTENDS EASTWARD FROM THE DUNE ON WHICH THE
 HU1579'STATION IS LOCATED, ABOUT 200 METERS TO NORMAL HIGH-WATER
 HU1579'MARK.  THE STORM HIGH-WATER MARK IS AT THE FOOT OF THE DUNE ON
 HU1579'WHICH THE STATION IS LOCATED, SOME 20 METERS E OF THE STATION.
 HU1579'
 HU1579'A SHALLOW SLOUGH EXTENDS FROM SINEPUXENT BAY THROUGH MARSH AND
 HU1579'BRUSH, ENDING AT A POINT ABOUT 100 METERS S OF THE STATION.

 HV4937'DESCRIBED BY COAST AND GEODETIC SURVEY 1926 (FLP)
 HV4937'TRIANGULATION STATION GUT 2 IS A THIRD ORDER STATION, AND IS
 HV4937'SITUATED ON THE POTOMAC RIVER, OPPOSITE THE ENTRANCE TO GUNSTON
 HV4937'COVE, AND ABOUT 3200 YARDS BELOW MARSHALL HALL.  IT IS NEAR THE
 HV4937'HIGH-WATER LINE AT THE EXTREMITY OF A SMALL POINT WHICH MAKES OUT
 HV4937'A SHORT DISTANCE S OF A SMALL STREAM.  AN EXISTING PROPERTY
 HV4937'MONUMENT, OR A PREVIOUS SURVEY MARK WAS USED FOR THE STATION
 HV4937'MARK.  THIS STATION MARK IS THE CENTER OF A CEMENT-FILLED
 HV4937'1-INCH IRON PIPE EMBEDDED IN A CYLINDRICAL BLOCK OF CONCRETE
 HV4937'ENCASED IN A SHEET IRON FORM, ABOUT 10 INCHES IN DIAMETER.  A
 HV4937'SMALL TACK IS EMBEDDED NEAR THE CENTER OF THE TOP SURFACE OF
 HV4937'THE CONCRETE INSIDE THE PIPE.  THE STATION MARK IS ABOUT
 HV4937'1.5 METERS OUTSIDE OF THE HIGH-WATER LINE, AND IS COVERED TO
 HV4937'A DEPTH OF 2 OR 3 INCHES AT HIGH WATER.  GUT 2 IS WITHIN 20
 HV4937'METERS OF THE LOCATION OF GUT 1902, WHICH WAS SEARCHED FOR
 HV4937'BUT NOT FOUND.
 HV4937'
 HV4937'REFERENCE MARKS ARE STANDARD BRONZE DISKS SET IN CONCRETE.
 HV4937'WITNESS MARK IS A TREE MARKED WITH A
 HV4937'TRIANGULAR BLAZE WITH A NAIL AT THE CENTER AND EACH APEX OF THE
 HV4937'TRIANGLE.

 JV3211.The horizontal coordinates were established by GPS observations
 JV3211.and adjusted by the National Geodetic Survey in February 2007.
 JV3211
 JV3211.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 JV3211.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 JV3211
 JV3211.The horizontal coordinates are valid at the epoch date displayed above
 JV3211.which is a decimal equivalence of Year/Month/Day.
 JV3211
 JV3211.The orthometric height was determined by differential leveling and
 JV3211.adjusted in June 1991.
 JV3211
 JV3211.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JV3211
 JV3211.The Laplace correction was computed from DEFLEC09 derived deflections.
 JV3211
 JV3211.The ellipsoidal height was determined by GPS observations
 JV3211.and is referenced to NAD 83.
 JV3211
 JV3211.The dynamic height is computed by dividing the NAVD 88
 JV3211.geopotential number by the normal gravity value computed on the
 JV3211.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 JV3211.degrees latitude (g = 980.6199 gals.).
 JV3211
 JV3211.The modeled gravity was interpolated from observed gravity values.
 JV3211
 JV3211. The following values were computed from the NAD 83(2007) position.

 HV7315'DESCRIBED BY COAST AND GEODETIC SURVEY 1907
 HV7315'ON THE WESTERN SHORE OF CHESAPEAKE BAY, ON THE HIGHEST POINT OF A
 HV7315'CLIFF WHICH RISES ABRUPTLY FROM BOTH N AND S, ABOUT 1 MILE S OF
 HV7315'PLUM POINT LANDING, ON LAND BELONGING (IN 1907) TO MRS. H.M.
 HV7315'WILSON.  THE NEXT HIGH HILL TO THE S IS COVERED WITH AN EXTENSIVE
 HV7315'PEACH ORCHARD.  THE LAND AT THE STATION IS CULTIVATED ON ALTERNATE
 HV7315'YEARS.  THE STATION IS 3.7 METERS (12 FEET) W FROM A WIRE FENCE
 HV7315'AND 4.5 METERS (15 FEET) FROM THE EDGE OF THE CLIFF.

 HV7832'THE STATION MARK WAS RECOVERED AND FOUND IN GOOD CONDITION, AS
 HV7832'DESCRIBED BY R.D. HORNE IN 1933.  THE TWO REFERENCE MARKS AND THE
 HV7832'AZIMUTH MARKS ESTABLISHED BY HIM WERE ALSO FOUND IN GOOD CONDITION.
 HV7832'THE DETAILS OF HIS DESCRIPTIONS WERE ALL CHECKED.  AN OLD
 HV7832'REFERENCE MARK WAS FOUND, ALTHOUGH THERE WAS NO MENTION OF IT IN
 HV7832'ANY AVAILABLE DESCRIPTIONS OF THIS STATION.  IT CONSISTS OF A
 HV7832'STANDARD REFERENCE TABLET SET IN THE CENTER OF THE TOP OF A TILE
 HV7832'FILLED WITH CONCRETE.  THE STATION NAME (HILL) IS
 HV7832'STAMPED ON IT ALONG WITH R.M. NO. 2.  THERE IS NO DATE.
 HV7832'
 HV7832'THE HILL ON WHICH THE STATION IS LOCATED IS BEING CUT AWAY FOR
 HV7832'GRAVEL, SO THE STATION MARK WILL PROBABLY BE LOST IN THE COURSE OF
 HV7832'ANOTHER YEAR.  FOR THIS REASON, THE REFERENCE MARKS WERE ALL TIED
 HV7832'IN WITH INVAR TAPE MEASUREMENTS AND FOUR POSITIONS OF THE
 HV7832'CIRCLE.

 JV6474
 JV6474.The height was determined by precise leveling from only one NSRS
 JV6474.bench mark.  This was not adequate "tie leveling" to NSRS and was
 JV6474.allowed ONLY to validate the GPS-derived height.

 HV4948'THE STATION WAS RECOVERED AS DESCRIBED.  THERE HAD BEEN SOME
 HV4948'CAVING OF THE BANK ON WHICH THE STATION IS LOCATED, BUT THE MARK
 HV4948'APPEARED TO BE UNDISTURBED.  A TRIANGLE WAS CLOSED AT THE STATION,
 HV4948'AND COMPARISON WITH THE RESULTS OF CHARLES PIERCE INDICATED THAT
 HV4948'THERE HAD BEEN NO MOVEMENT.  THE STATION IS ON THE NON-PROMINENT,
 HV4948'ROUNDING POINT N OF MARSHALL HALL, APPROXIMATELY HALFWAY BETWEEN
 HV4948'MARSHALL HALL, AND THE FIRST HOUSE TO THE NORTHWARD THAT STANDS
 HV4948'AT THE TOP OF THE BLUFF ALONG THE WATERS EDGE.  THE STATION WAS
 HV4948'RECOVERED FROM THE PROGRESS SKETCH OF CHARLES PIERCE, THE OLD
 HV4948'STAND WAS INDISTINCT ON ACCOUNT OF HAVING ASSUMED THE COLOR OF THE
 HV4948'SURROUNDING VEGETATION.

 HV0021.The horizontal coordinates were established by GPS observations
 HV0021.and adjusted by the National Geodetic Survey in February 2007.
 HV0021
 HV0021.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). 
 HV0021.See www.ngs.noaa.gov/web/surveys/NSRS2007 for more information. 
 HV0021
 HV0021.The horizontal coordinates are valid at the epoch date displayed above
 HV0021.which is a decimal equivalence of Year/Month/Day.
 HV0021
 HV0021.The orthometric height was determined by differential leveling and
 HV0021.adjusted in June 1991.
 HV0021
 HV0021.Photographs are available for this station.
 HV0021
 HV0021.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 HV0021
 HV0021.The Laplace correction was computed from DEFLEC09 derived deflections.
 HV0021
 HV0021.The ellipsoidal height was determined by GPS observations
 HV0021.and is referenced to NAD 83.
 HV0021
 HV0021.The dynamic height is computed by dividing the NAVD 88
 HV0021.geopotential number by the normal gravity value computed on the
 HV0021.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV0021.degrees latitude (g = 980.6199 gals.).
 HV0021
 HV0021.The modeled gravity was interpolated from observed gravity values.
 HV0021
 HV0021.The observed gravity was obtained from relative gravimeter ties
 HV0021.to the IGSN71 gravity network.
