 MY2539'THIS STATION MARKS THE BOUNDARY LINE BETWEEN TOWNS OF NEWTON AND
 MY2539'PLAISTOW NEW HAMPSHIRE AND THE TOWNS OF HAVERHILL AND MERRIMAC
 MY2539'MASSACHUSETTS.
 MY2539'
 MY2539'THIS BOUNDARY POINT WAS ORIGINALLY MARKED IN 1827 AND SURVEYED BY
 MY2539'SIMEON BORDEN IN 1834 AS PART OF HIS TRIANGULATION OF MASSACHUSETTS
 MY2539'(1830-1838).  THIS POINT IS ONE OF 8 SUCH POINTS SURVEYED BY BORDEN ON
 MY2539'THE MASSACHUSETTS - NEW HAMPSHIRE LINE AND WAS ORIGINALLY KNOWN AS
 MY2539''BRANDY BROW HILL'.
 MY2539'
 MY2539'THE BORDEN POINTS ARE DOCUMENTED IN THE BULLETIN OF THE USGS NO. 13
 MY2539'(1885) 'BOUNDARIES OF THE UNITED STATES AND OF THE SEVERAL STATES AND
 MY2539'TERRITORIES' BY HENRY GANNETT, CHIEF GEOGRAPHER.  IN THE SECTION ON
 MY2539'THE BOUNDARIES OF MASSACHUSETTS, A TABLE LISTS THESE 8 BORDEN POINTS
 MY2539'WITH GEOGRAPHIC LOCATIONS ALONG WITH POINTS ON THE BOUNDARIES WITH
 MY2539'OTHER STATES.
 MY2539'
 MY2539'THE CURRENT MONUMENT WAS SET IN 1890 AND CONSISTS OF A GRANITE POST
 MY2539'ABOUT 4 FEET HIGH AND ABOUT 15 INCHES SQUARE.  ON THE NH SIDE IT IS
 MY2539'INSCRIBED 'N + P, NH, 1890' AND ON THE MASSACHUSETTS SIDE 'H + M,

 OC2490
 OC2490'DESCRIBED BY COAST AND GEODETIC SURVEY 1908 (OBF)
 OC2490'STATION IS ON THE SUMMIT OF THE HILL KNOWN AS BUNKER HILL
 OC2490'SOME 3 MILES N OF THE TOWN OF EXETER AND NEAR THE TOWN OF
 OC2490'STRATHAM.  THE STATION IS MARKED BY A HALF-INCH DRILL HOLE
 OC2490'(SHALLOW) IN A TRIANGLE IN A LARGE ROCK JUST ABOUT FLUSH WITH
 OC2490'THE TOP OF THE GROUND AND ABOUT ON THE W SIDE OF THE HIGHEST
 OC2490'PART OF THE HILL.  A LARGE SPLIT BOULDER IS ABOUT 60 FEET NE
 OC2490'OF THE STATION AND A VERY TALL ONE ABOUT SE.

 OC2490
 OC2490'RECOVERY NOTE BY NEW HAMPSHIRE GEODETIC SURVEY 1930
 OC2490'BUNKER HILL (NOT THE HISTORIC HILL OF THAT NAME, HOWEVER)
 OC2490'IS NOT FAR FROM WHERE I AM NOW LIVING AND I HAVE BEEN THERE
 OC2490'FREQUENTLY.  FOR SOME TIME, I WAS UNABLE TO FIND THE TRIANGULATION
 OC2490'STATION, HOWEVER, PARTLY AT LEAST BECAUSE OF THE MEAGER AND
 OC2490'INACCURATE ORIGINAL DESCRIPTION.  FINALLY I CUT OUT SOME OF
 OC2490'THE SMALL BIRCHES SO THAT I COULD SEE STATIONS MARK AND
 OC2490'STRATHAM TALL CHURCH SPIRE IN LINE AND THEN, ON NOV. 23, 1930,
 OC2490'I FOUND THE STATION.  IT WAS IN A CLUMP OF BIRCHES AND COVERED
 OC2490'WITH LEAVES.  THE MARK SEEMED TO HAVE BEEN CHIPPED IN SUCH
 OC2490'A WAY THAT THE DRILL HOLE HAD DISAPPEARED AND ONLY A PART
 OC2490'OF THE TRIANGLE REMAINED.  THE STONE DID NOT IMPRESS ME AS
 OC2490'BEING A STABLE OR SATISFACTORY STATION MARK, AND WHAT WAS
 OC2490'LEFT OF THE TRIANGLE WAS ON THE EXTREME EDGE, WHICH
 OC2490'SUGGESTED THAT PERHAPS THE STONE HAD BEEN PARTLY ROTATED BY
 OC2490'FROST ACTION OR OTHERWISE.
 OC2490'
 OC2490'A SPLIT BOULDER, DOUBTLESS THE ONE REFERRED TO IN THE PRINTED
 OC2490'DESCRIPTION HAS A 3-INCH TRIANGLE (NOT MENTIONED IN THE
 OC2490'DESCRIPTION) CUT IN IT, THE TRIANGLE BEING ABOUT 86.4 FEET
 OC2490'FROM THE STATION, ABOUT S 54 DEG W.  THIS BOULDER
 OC2490'IS SUBSTANTIAL, BEING ABOUT 9 FEET LONG, NEARLY AS WIDE AND
 OC2490'ABOUT 3 FEET HIGH.  THERE IS NO OTHER SPLIT BOULDER IN THE
 OC2490'VICINITY, SO THIS MUST BE THE ONE DESCRIBED AS BEING ABOUT
 OC2490'60 FEET NE OF THE STATION, THE DISTANCE BEING APPARENTLY AN
 OC2490'ERROR.  THE VERY TALL BOULDER MENTIONED IS ACTUALLY ABOUT
 OC2490'2-1/2 FEET HIGH, ABOUT 2-1/2 FEET IN DIAMETER AT THE BASE,
 OC2490'AND MORE OR LESS CONICAL, WITH A 3 1/2-INCH TRIANGLE CUT
 OC2490'IN THE TOP, BUT NOT MENTIONED IN THE DESCRIPTION.  THIS
 OC2490'TRIANGLE IS ABOUT 84.5 FEET FROM THE STATION,
 OC2490'ABOUT N 30 DEG 07 MIN W.
 OC2490'
 OC2490'I AM REASONABLY SURE THAT THE MARK I HAVE DESCRIBED IS THE
 OC2490'STATION, AND THE DIRECTIONS TO SUCH NEARBY OBJECTS (STRATHAM,
 OC2490'MARK, STRATHAM TALL SPIRE, EXETER STANDPIPE) AS I COULD SEE,
 OC2490'HAVE CHECKED TO THE NEAREST MINUTE, WHICH IS AS CLOSE AS I
 OC2490'ATTEMPTED TO READ MY SMALL ENGINEERS TRANSIT.  I THINK THERE
 OC2490'IS A DECIDED POSSIBILITY THAT THE STONE MAY NOT BE IN EXACTLY
 OC2490'ITS ORIGINAL POSITION, HOWEVER.
 OC2490'
 OC2490'THE HILL IS COVERED WITH SMALL BIRCHES AND THE VIEW IS VERY
 OC2490'LIMITED.  THE PRESENT OWNER OF THE PROPERTY, R.E. HOLMES,
 OC2490'OF STRATHAM, TELLS ME, HOWEVER, THAT HE EXPECTS SOON TO CUT
 OC2490'OFF THE TREES AND UNDERBRUSH, AND USE THE LAND IN HIS POULTRY
 OC2490'BUSINESS, AS A RANGE FOR HENS.

 OC2490'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1943 (FLG)
 OC2490'STATION NOT RECOVERED.  TWO HOURS WERE SPENT SEARCHING FOR
 OC2490'THIS STATION WITHOUT SUCCESS.  IT IS RECOMMENDED THAT THIS
 OC2490'STATION BE CLASSIFIED AS LOST.

 OC1376'STATION IS ON THE SOUTHWESTERN
 OC1376'SUMMIT OF CATAMOUNT MOUNTAIN, WHICH IS ABOUT 2-1/2 MILES
 OC1376'SE OF THE TOWN OF PITTSFIELD.  THE LOCALITY IS WELL SHOWN ON THE
 OC1376'U.S.G.S. GILMANTON SHEET.  THE BEST APPROACH IS FROM THE
 OC1376'S SIDE, WHERE A FAIRLY GOOD TRAIL LEADS NEARLY TO THE SUMMIT,
 OC1376'THROUGH AN OPEN PASTURE AND SOME WOODLAND.  THERE ARE SEVERAL
 OC1376'BARE LEDGES ON THE SUMMIT AND THE STATION IS ON ONE OF THESE.
 OC1376'ABOUT 124 FEET SSW OF THE STATION IS A PROMINENT CAIRN, BUILT
 OC1376'OF FLAT STONES AND MORE OR LESS SQUARE IN CROSS-SECTION, AND A
 OC1376'SIMILAR CAIRN IS ABOUT 192 FEET NNE OF THE STATION.
 OC1376'
 OC1376'THE STATION IS MARKED BY AN 8-INCH TRIANGLE, IN THE CENTER OF
 OC1376'WHICH IS A DRILL HOLE WITH A METAL BOLT ADJACENT TO IT.  THE
 OC1376'HEAD OF THE BOLT IS ROUGH AND IRREGULAR, AND IT IS ABOUT 1/2
 OC1376'INCH W OF THE DRILL HOLE.
 OC1376'
 OC1376'I FOUND NEAR THE STATION SEVERAL DRILL HOLES (SOME OF THEM

 OC1376'THE HOLES MIGHT SERVE AS REFERENCE MARKS IN FINDING THE
 OC1376'STATION OR IN REPLACING IT, IF IT SHOULD BE DESTROYED, SO I
 OC1376'HAVE GIVEN THEIR POSITIONS AS WELL AS POSSIBLE UNDER THE

 OC1335
 OC1335'DESCRIBED BY COAST AND GEODETIC SURVEY 1878
 OC1335'IN THE TOWNSHIP OF GUILFORD, ABOUT 5 MILES IN AN EASTERLY
 OC1335'DIRECTION FROM LACONIA ON THE LAND OWNED BY COL. BENJAMIN F.
 OC1335'WEEKS, ABOUT 2,440 FEET ABOVE THE MEAN-SEA LEVEL.  THE ASCENT OF
 OC1335'THE MOUNTAIN IS QUITE STEEP ON ALL SIDES, BUT LEAST STEEP
 OC1335'ON THE WESTERN SLOPE WHERE A ROAD WAS CONSTRUCTED IN THE FALL
 OC1335'OF 1859.
 OC1335'
 OC1335'THE STATION IS MARKED BY A COPPER BOLT IN THE ROCK AT THE
 OC1335'SUMMIT OF THE MOUNTAIN.  THE ASTRONOMICAL OBSERVATORY WAS
 OC1335'PLACED ABOUT 100 FEET TO THE NORTHWARD ON A BARE ROCK.  IN
 OC1335'1878 ANOTHER BOLT WAS PLACED 0.635 METER FROM THE STATION,
 OC1335'N 88 DEG 45 MIN W.

 OC1335                          STATION RECOVERY (1931)
 OC1335
 OC1335'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1931 (HSS)
 OC1335'THE STATION IS ON WHAT IS KNOWN
 OC1335'AS BELKNAP MOUNTAIN, THE NAME GUNSTOCK NOW BEING APPLIED TO
 OC1335'A PEAK ABOUT 3/4 MILE TO THE NW.
 OC1335'
 OC1335'I WENT TO THE MOUNTAIN ON SEPT. 29, 1931 AND FOUND NO COPPER
 OC1335'BOLTS ON THE SUMMIT, BUT THERE WERE NUMEROUS DRILL HOLES,
 OC1335'ONE OF WHICH I THOUGHT MIGHT BE THE STATION, AS THERE WAS
 OC1335'ANOTHER HOLE 2.13 FEET E OF IT, WHICH WAS ABOUT 0.05 FEET
 OC1335'GREATER THAN THE 0.635 METER GIVEN IN THE PRINTED DESCRIPTION.
 OC1335'I STARTED TO MEASURE THE DISTANCES TO OTHER DRILL HOLES, BUT
 OC1335'BECAME DISCOURAGED WHEN, IN A CASUAL SEARCH, I FOUND AT LEAST
 OC1335'21 OF THEM, WITHIN 50 FEET OR SO OF THE 2 HOLES MENTIONED
 OC1335'ABOVE.  PROBABLY SOME OF THESE HOLES MAY BE REFERENCE OR
 OC1335'RANGE HOLES, AND IF ANY INFORMATION ABOUT THEM IS AVAILABLE I
 OC1335'SHALL TRY TO VISIT THE MOUNTAIN AGAIN NEXT YEAR.
 OC1335'
 OC1335'THE FIRE TOWER WAS A LITTLE W OF N AND ABOUT 44-1/2 FEET
 OC1335'DISTANT FROM THE DRILL HOLE WHICH I THOUGHT MIGHT BE THE
 OC1335'STATION, THIS DISTANCE BEING SOMEWHAT GREATER THAN WOULD BE
 OC1335'INDICATED BY THE GEOGRAPHIC POSITION OF THE TOWER, WHICH
 OC1335'WAS USED BY THE U.S.G.S. AS AN UNOCCUPIED STATION IN 1916-18.
 OC1335'THERE IS A GOOD VIEW IN ALL DIRECTIONS FROM THE SUMMIT.
 OC1335'
 OC1335'THE STATION MAY BE REACHED BY EITHER OF TWO TRAILS WHICH
 OC1335'LEAD TO THE FIRE TOWER, ONE ON THE LACONIA SIDE AND THE
 OC1335'OTHER ON THE NE SIDE.
 OC1335
 OC1335                          STATION RECOVERY (1932)
 OC1335
 OC1335'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1932 (HSS)
 OC1335'I RECOVERED THIS STATION ON
 OC1335'JUNE 15, 1932, THE COPPER BOLT BEING STILL FIRMLY IN PLACE.
 OC1335'THE BOLT HAD BEEN FOUND BY THE FIRE WATCHMAN, WHOSE INTEREST
 OC1335'HAD BEEN AROUSED BY AN UNSUCCESSFUL SEARCH WHICH I HAD
 OC1335'MADE ABOUT A MONTH BEFORE, AND HE REPORTED THAT THE BOLT
 OC1335'HAD BEEN COVERED WITH DIRT AND THAT IT HAD BEEN PARTLY HIDDEN
 OC1335'BY A THIN LAYER OF CEMENT.  I NOTICED THE CEMENT ON THE LEDGE
 OC1335'AROUND THE BOLT AND I FOUND A ROUGH CONCRETE BLOCK LYING
 OC1335'NOT FAR AWAY.  THIS WAS ABOUT 2 FEET HIGH, WITH A TRIANGULAR
 OC1335'BASE, AND IT HAD EVIDENTLY ONCE SERVED AS A MONUMENT
 OC1335'CEMENTED OVER THE STATION.  I HAVE NOT BEEN ABLE TO
 OC1335'ASCERTAIN WHO BUILT IT.  I REPLACED IT OVER THE BOLT,
 OC1335'BUT THERE IS NO ASSURANCE THAT IT WILL REMAIN IN
 OC1335'PLACE, AS IT IS NOT FASTENED IN ANY WAY.  I FOUND ABOUT 40
 OC1335'DRILL HOLES, ALL BUT ABOUT 2 OF WHICH WERE WITHIN 50
 OC1335'FEET OF THE STATION, AND I IDENTIFIED 7 OF THESE AS BEING
 OC1335'RANGE HOLES WHICH ARE SHOWN ON THE SKETCH IN THE
 OC1335'ORIGINAL DESCRIPTION OF THE STATION.
 OC1335'
 OC1335'THE AZIMUTHS AND DISTANCES CHECKED NICELY.  I FOUND THE BOLT
 OC1335'OF 1878, MENTIONED IN THE PRINTED DESCRIPTION, AND IT WAS
 OC1335'RUSTY AND EVIDENTLY OF IRON.
 OC1335'
 OC1335'THE CENTER OF THE STEEL FIRE TOWER IS, ACCORDING TO MY
 OC1335'MEASUREMENTS, 56.45 FEET FROM THE STATION, IN AZIMUTH ABOUT
 OC1335'167-1/2 DEG, AND THIS FORMS A CONVENIENT WAY OF FINDING
 OC1335'THE STATION.
 OC1335'
 OC1335'THREE DRILL HOLES ARE QUITE NEAR THE STATION, AS FOLLOWS--
 OC1335'1.52 FEET, 22-1/2 DEG.  1.62 FEET, 145 DEG.  2.46 FEET, 221
 OC1335'DEG.  THESE AZIMUTHS WERE DETERMINED ONLY VERY ROUGHLY, TO
 OC1335'GIVE A GENERAL IDEA OF THE LOCATION OF THE HOLES.

 OC1335
 OC1335'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1933 (HSS)
 OC1335'THIS NOTE IS
 OC1335'SUPPLEMENTARY TO THE ONE WHICH I PREPARED IN 1932, SOON
 OC1335'AFTER I RECOVERED THE STATION.  IN THAT NOTE I MENTIONED
 OC1335'A CONCRETE MONUMENT WHICH I FOUND LYING NEAR THE STATION
 OC1335'AND WHICH HAD EVIDENTLY ONCE BEEN PLACED OVER THE STATION.
 OC1335'I WAS AT THAT TIME UNABLE TO LEARN WHO BUILT THE MONUMENT, BUT
 OC1335'ON A RECENT VISIT TO THE WASHINGTON OFFICE I FOUND A RECORD
 OC1335'WHICH SHOWED THAT IT HAD BEEN CONSTRUCTED BY THE PARTY OF
 OC1335'A.T. MOSMAN, IN 1897.  IT WAS DESCRIBED AS A PIER 4-1/2 FEET
 OC1335'HIGH, ON WHICH A THEODOLITE HAD BEEN SUPPORTED, BUT THE
 OC1335'PIECE WHICH I FOUND WAS ONLY ABOUT 2 FEET HIGH AND
 OC1335'THEREFORE, ONLY A PART OF THE ORIGINAL STRUCTURE.
 OC1335'
 OC1335'THE PEAK ON WHICH THE STATION IS LOCATED IS NOW CALLED BELKNAP
 OC1335'MOUNTAIN AND ANOTHER PEAK ABOUT 3/4 MILE TO THE NW IS CALLED
 OC1335'GUNSTOCK MOUNTAIN.

 MY5382
 MY5382'RECOVERY NOTE BY NEW HAMPSHIRE GEODETIC SURVEY 1930
 MY5382'I VISITED THIS STATION ON DECEMBER 19, 1930 AND WAS ABLE TO DRIVE
 MY5382'TO IT IN MY CAR BY FOLLOWING A CART-ROAD FROM THE HOUSE OF
 MY5382'W.E. MOORE, WHO IS THE PRESENT OWNER OF THE PROPERTY.  STATION WAS
 MY5382'IN GOOD ORDER, WITH THE BOLT FIRMLY IN PLACE.  IT IS LOCATED IN A
 MY5382'HAY FIELD AND THE VIEW IS UNOBSTRUCTED.
 MY5382'
 MY5382'I FAILED TO FIND THE BOULDER, AND IT WAS
 MY5382'PROBABLY REMOVED IN THE CULTIVATION OF THE LAND.  THE SPRUCE TREE
 MY5382'DOES NOT EXIST, BUT THERE IS A LARGE WHITE PINE
 MY5382'IN APPARENTLY THE SAME PLACE, WHICH MAY BE THE TREE REFERRED TO,
 MY5382'AS IT MUST HAVE BEEN THERE FOR MANY YEARS, THE TRUNK BEING ABOUT
 MY5382'TWO FEET IN DIAMETER.  THERE ARE NO OTHER LARGE TREES IN THE
 MY5382'VICINITY.  THE ARROWHEAD IS HARDLY
 MY5382'RECOGNIZABLE AS SUCH AND IS SO INCONSPICUOUS AS TO BE USELESS AS
 MY5382'A FINDER.
 MY5382'
 MY5382'REFERENCE MARK NO.1 IS FIRMLY IN PLACE, BUT THE DISK IS ABOUT 1-1/2
 MY5382'INCHES ABOVE THE SURFACE OF THE ROCK AND THE ARROW POINTS ABOUT
 MY5382'15 DEG TO THE LEFT OF THE STATION.  REFERENCE MARK NO.2 IS LOOSE
 MY5382'ENOUGH TO BE EASILY LIFTED OUT AND THE DISK IS ABOUT AN INCH ABOVE
 MY5382'THE SURFACE.

 AH8869.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AH8869.been affixed to the stable North American tectonic plate. See 
 AH8869.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AH8869
 AH8869.The horizontal coordinates are valid at the epoch date displayed above
 AH8869.which is a decimal equivalence of Year/Month/Day.
 AH8869
 AH8869.The orthometric height was determined by GPS observations and a
 AH8869.high-resolution geoid model.
 AH8869
 AH8869.GPS derived orthometric heights for airport stations designated as
 AH8869.PACS or SACS are published to 2 decimal places.  This maintains
 AH8869.centimeter relative accuracy between the PACS and SACS.  It does
 AH8869.not indicate centimeter accuracy relative to other marks which are
 AH8869.part of the published vertical control network.
 AH8869
 AH8869.Significant digits in the geoid height do not necessarily reflect accuracy.

 MZ2648
 MZ2648.The horizontal coordinates were established by GPS observations
 MZ2648.and adjusted by the National Geodetic Survey in June 2012.
 MZ2648
 MZ2648.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MZ2648.been affixed to the stable North American tectonic plate. See 
 MZ2648.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MZ2648
 MZ2648.The horizontal coordinates are valid at the epoch date displayed above
 MZ2648.which is a decimal equivalence of Year/Month/Day.
 MZ2648
 MZ2648.The orthometric height was determined by GPS observations and a
 MZ2648.high-resolution geoid model.
 MZ2648
 MZ2648.GPS derived orthometric heights for airport stations designated as
 MZ2648.PACS or SACS are published to 2 decimal places.  This maintains
 MZ2648.centimeter relative accuracy between the PACS and SACS.  It does
 MZ2648.not indicate centimeter accuracy relative to other marks which are
 MZ2648.part of the published vertical control network.
 MZ2648
 MZ2648.Significant digits in the geoid height do not necessarily reflect accuracy.
 MZ2648.GEOID18 height accuracy estimate available here.

 MZ1473
 MZ1473'DESCRIBED BY COAST AND GEODETIC SURVEY 1896
 MZ1473'STATION IS ON THE HIGHEST PART OF MONADNOCK MOUNTAIN, WHICH
 MZ1473'IS IN THE TOWNS OF JAFFREY, DUBLIN AND MARLBORO.  THE STATION
 MZ1473'IS ON A COMPARATIVELY LEVEL ROCK, WITH A HIGHER ROCK TO THE
 MZ1473'N.  IT IS MARKED BY A DRILL HOLE IN A ROCK.  THERE IS A DRILL HOLE
 MZ1473'BESIDE THE ONE WHICH MARKS THE STATION OPENING INTO IT AND
 MZ1473'ANOTHER 7/8 INCH DISTANT, WITH AN IRON BOLT IN IT.  THERE
 MZ1473'ARE 5 LINES CUT IN THE ROCK RADIATING FROM THE CENTER HOLE.
 MZ1473'
 MZ1473'FIVE REFERENCE MARKS, DRILL HOLES IN ROCKS WITH SQUARES
 MZ1473'AROUND THEM AND WITH ARROWS POINTING TO THE STATION, ARE
 MZ1473'LOCATED AS FOLLOWS--NO. 1 DISTANT 11.52 METERS (38.80 FEET),

 MZ1473
 MZ1473'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1932 (HSS)
 MZ1473'STATION MAY BE REACHED FROM
 MZ1473'THE HIGHWAY BETWEEN JAFFREY AND TROY.  AT A POINT ABOUT S
 MZ1473'OF THE MOUNTAIN A PRIVATE TOLL ROAD RUNS N ABOUT 1.3 MILES TO
 MZ1473'A SMALL HOTEL, CALLED THE HALF WAY HOUSE, AND FROM THERE A
 MZ1473'STEEP AND ROCKY, BUT MUCH USED TRAIL LEADS TO THE SUMMIT,
 MZ1473'THE ASCENT REQUIRING ABOUT 3/4 HOUR.  THERE ARE SEVERAL OTHER
 MZ1473'TRAILS ON THE MOUNTAIN.  THE UPPER PART OF THE MOUNTAIN
 MZ1473'CONSISTS OF BARE LEDGES AND THE SUMMIT IS RATHER SHARPLY
 MZ1473'POINTED.
 MZ1473'
 MZ1473'THE STATION IS MARKED AS DESCRIBED AND I HAD NO DIFFICULTY
 MZ1473'IN IT WHEN I VISITED THE MOUNTAIN IN 1932.  THE TRIANGLE AND 5
 MZ1473'RADIAL LINES ARE STILL DISTINCT, ALTHOUGH NOT DEEPLY CUT IN
 MZ1473'THE LEDGE.  THE TRIANGLE, WHICH IS LARGE, APPEARS TO BE CENTERED
 MZ1473'ON THE HOLE (ONE OF 3 WITHIN THE TRIANGLE) WHICH IS DESCRIBED
 MZ1473'AS BEING THE STATION POINT.  I FOUND MANY DRILL HOLES, OF
 MZ1473'VARIOUS SIZES, ON THE SUMMIT, SEVERAL OF THEM BEING WITHIN A FEW
 MZ1473'FEET OF THE STATION, BUT, I FAILED TO IDENTIFY ANY OF
 MZ1473'THEM, IN A HASTY SEARCH, AS BEING THE REFERENCE MARKS
 MZ1473'MENTIONED IN THE DESCRIPTION, ALTHOUGH SOME OF THEM MAY
 MZ1473'STILL EXIST.  A U.S.G.S. DISK, UNSTAMPED, IS CEMENTED IN
 MZ1473'THE LEDGE AT A DISTANCE OF 1.04 FEET IN A SOUTHWESTERLY
 MZ1473'DIRECTION FROM THE STATION.  IT WAS SET BY MR. C.B. KENDALL
 MZ1473'IN 1931.
 MZ1473'
 MZ1473'NEAR THE STATION IS A FIRE LOOKOUT CABIN, CONSISTING OF A
 MZ1473'MASONRY WALL SURMOUNTED BY SEVERAL WINDOWS ON A LOW ROOF.  THE
 MZ1473'STATION IS ABOUT 5 FEET N OF THE NE CORNER OF THE CABIN.  THE VIEW
 MZ1473'FROM THE SUMMIT IS UNOBSTRUCTED IN ALL DIRECTIONS.  A LARGE
 MZ1473'PART OF THE MOUNTAIN IS IN PUBLIC OWNERSHIP, THE SUMMIT
 MZ1473'BEING OWNED BY EITHER THE TOWN OF JAFFREY, OR THE SOCIETY FOR
 MZ1473'THE PROTECTION OF NEW HAMPSHIRE FORESTS, THERE BEING SOME
 MZ1473'UNCERTAINTY AS TO THE POSITION OF THE BOUNDARY LINE.
 MZ1473'
 MZ1473'I FOUND A DRILL HOLE WHICH I TOOK TO BE THE BORDEN STATION,
 MZ1473'MENTIONED IN THE DESCRIPTION, THE DISTANCE AND AZIMUTH AGREEING
 MZ1473'WITH THOSE GIVEN.  THE HOLE HAS A CONICAL OPENING, WHICH
 MZ1473'SUGGESTED THAT THE ROCK HAD BEEN CHIPPED AWAY BY SOMEONE
 MZ1473'WHO MAY HAVE REMOVED THE COPPER BOLT WHICH DOUBTLESS ORIGINALLY
 MZ1473'WAS IN THE HOLE.
 MZ1473'
 MZ1473'NOTE--THIS STATION IS DATED 1860 BUT 1861 IS GIVEN IN THE ORIGINAL
 MZ1473'DESCRIPTION AND ON THE SKETCHES IN THE ANNUAL REPORTS.

 PF0950'THE POSITION IS MARKED BY 2 SEMI-CIRCLES, ONE UPON EACH SIDE OF ROOF,
 PF0950'THE CENTER OF THE TWO BEING 13.67 FEET FROM THE FRONT END OF
 PF0950'BUILDING AND 11.50 FEET FROM THE EAVES.  THREE 4-INCH SCREWS ARE SET
 PF0950'IN THE CIRCUMFERENCE OF THE CIRCLE, FORMING AN EQUILATERAL

 PF0950'THE BOLT MARKING THE MOUNT WASHINGTON STATION WAS FOUND, AFTER THE
 PF0950'REMOVAL OF A PORTION OF THE PLANK FLOOR OF THE OBSERVATORY, AND
 PF0950'CONSIDERABLE RUBBISH UNDERNEATH IT.
 PF0950'
 PF0950'THE BOLT IS COPPER, 1 INCH IN DIAMETER, PROJECTS ABOUT 1/4 INCH ABOVE
 PF0950'THE ROCK AND HAS A TOP IN THE FORM OF A TRUNCATED CONE WHICH IS BUT
 PF0950'SLIGHTLY MARRED.  IT IS IMBEDDED IN A SOLID DEPRESSION (NOT A
 PF0950'CREVICE) OF WHAT AT FIRST APPEARS TO BE BEDROCK BUT WHICH IS PROBABLY
 PF0950'ONLY A VERY LARGE ROCK JUDGING FROM THE OUTSIDE APPEARENCE OF THE
 PF0950'SUMMIT.  THE DEPRESSION WHERE THE BOLT IS LOCATED IS 2-1/2 FEET
 PF0950'BELOW AND ABOUT 5 FEET WNW FROM THE HIGHEST POINT OF THE ROCK WHICH
 PF0950'PROJECTS ABOVE THE FLOOR INTO THE OBSERVATORY.

 PF0950
 PF0950'RECOVERY NOTE BY US GEOLOGICAL SURVEY 1921
 PF0950'AN ATTEMPT WAS MADE TO RECOVER THIS STATION, BUT IT WAS IMPOSSIBLE TO
 PF0950'FIND POSITIVE EVIDENCE OF ITS EXACT POSITION.  TWO IRON PINS SUCH AS
 PF0950'WERE FOUND ON MT. MORIAH WERE IN PLACE AND A HOLE IN THE ROCK THAT
 PF0950'MAY HAVE CONTAINED THE STATION MARK WAS SEEN.  THE COPPER BOLT
 PF0950'SUPPOSED TO MARK THE STATION WAS NOT FOUND.  A LARGE WATER TANK NOW
 PF0950'COVERS THE TOP OF THE MOUNTAIN AND THERE IS A POSIBILITY THAT THE
 PF0950'SUMMIT WAS BLOWN OFF TO MAKE A SUITABLE FOUNDATION FOR IT.

 PF0950
 PF0950'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1933 (HSS)
 PF0950'RECOVERY NOTE OF H.S. SHAW--THE STATION IS WITHIN A FEW FEET OF THE
 PF0950'HIGHEST POINT OF THE MOUNTAIN AND MAY BE REACHED BY A PRIVATE TOLL
 PF0950'ROAD ON THE E SIDE OF THE MOUNTAIN, OR BY A COG RAILROAD ON THE W
 PF0950'SIDE.  THE ROAD, 8 MILES LONG, IS USUALLY PASSABLE FOR AUTOMOBILES
 PF0950'FROM ABOUT JUNE 1, UNTIL IT IS BLOCKED BY SNOW IN THE FALL, AND
 PF0950'THE RAILROAD IS IN OPERATION DURING THE SUMMER MONTHS ONLY.
 PF0950'
 PF0950'NEAR THE HIGHEST POINT OF THE MOUNTAIN IS A WOODEN WATER TANK, ABOUT
 PF0950'22 FEET IN DIAMETER AND 16 FEET HIGH, SUPPORTED ON HEAVY TIMBERS.
 PF0950'THESE TIMBERS REST ON THE ROCK AND ON HEAVY BLOCKS, BETWEEN TWO OF
 PF0950'WHICH THE BOLT CAN BE SEEN ABOUT 2 FEET UNDER THE TANK.  THE BOLT
 PF0950'APPEARS TO BE FIRMLY IN PLACE AND A CROSS IS STILL DISCERNIBLE ON
 PF0950'ITS ROUNDED HEAD.  A U.S.G.S. BENCH MARK, STAMPED 6284 FEET MARKS
 PF0950'THE HIGHEST POINT OF THE ROCK AND THE BOLT BEARS A LITTLE S OF W
 PF0950'FROM THE BENCH MARK, DISTANT AN INCH OR TWO MORE THAN 5 FEET,
 PF0950'MEASURED ALONG THE SLOPE, THE ELEVATION OF THE BOLT BEING SOME 2
 PF0950'1/2 FEET BELOW THE BENCH MARK.  THESE MEASUREMENTS WERE MADE ONLY
 PF0950'ROUGHLY, BECAUSE OF THE PRESENCE OF THE TANK.
 PF0950'
 PF0950'THE VIEW FROM THE VICINITY OF THE STATION IS OBSTRUCTED BY BUILDINGS
 PF0950'AND BY THE TANK, EXCEPT FROM ABOUT WNW THROUGH N TO ABOUT ENE.  IN
 PF0950'THE GENERAL VICINITY OF THE STATION I FOUND SEVERAL IRON BOLTS, WHICH
 PF0950'APPEARED TO HAVE ONCE SERVED AS ANCHOR BOLTS FOR THE OLD
 PF0950'OBSERVATORY OR FOR OTHER STRUCTURES.  AT THE TIME OF MY VISIT, JUNE
 PF0950'4, 1933, THE FOLLOWING BUILDINGS WERE ON THE SUMMIT--SUMMIT HOUSE,
 PF0950'A WOODEN HOTEL.  TIP TOP HOUSE, WITH WALLS OF LOOSE STONES
 PF0950'AND A WOODEN ROOF, CONNECTED WITH THE SUMMIT HOUSE BY A COVERED
 PF0950'PASSAGEWAY.  CAMDEN COTTAGE, A WOODEN BUILDING USED AS A CAMP
 PF0950'BY CLIMBERS.  STAGE OFFICE, ALSO OF WOOD, USED BY PATRONS OF THE
 PF0950'AUTO ROAD AND ALSO OCCUPIED AS A METEOROLOGICAL OBSERVATORY IN
 PF0950'1932-3, DURING THE INTERNATIONAL POLAR YEAR.  THERE IS ALSO A
 PF0950'GARAGE JUST BELOW THE SUMMIT.  ALL THESE BUILDINGS HAVE BEEN
 PF0950'BUILT SINCE JUNE 1908, WHEN A FIRE SWEPT THE SUMMIT AND
 PF0950'DESTROYED EVERYTHING BUT THE STONE WALLS OF THE TIP TOP HOUSE.
 PF0950'THE OBSERVATORY, OR TOWER, WHICH WAS SITUATED OVER THE STATION FOR
 PF0950'MANY YEARS, IS SAID TO HAVE BEEN PULLED DOWN IN 1902.

 PF0950
 PF0950'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1934 (KGC)
 PF0950'THE COPPER BOLT MARKING THE STATION WAS FOUND AS DESCRIBED BY H.S.
 PF0950'SHAW IN HIS NOTE OF 1933.  THE BOLT CHECKS THE DESCRIPTION OF
 PF0950'C.C.Y., IN 1897 THE ONLY EXCEPTION NOTED WAS THAT IS SEEMS TO BE
 PF0950'MORE NEARLY W THAN WNW (AS STATED IN HIS NOTE) FROM THE
 PF0950'HIGHEST POINT ON THE MOUNTAIN, HOWEVER, ON ACCOUNT OF THICK
 PF0950'WEATHER AN ACCURATE DIRECTION COULD NOT BE DETERMINED.  THE
 PF0950'BOLT IS NOW UNDER A WOODEN WATER TANK.  THE TANK IS ABOUT 22 FEET
 PF0950'IN DIAMETER AND 16 FEET IN HEIGHT AND IS SUPPORTED BY A CRIBBING
 PF0950'OF 12- BY 12-INCH TIMBERS.  THE BOLT IS ABOUT 2 FEET UNDER THE NW
 PF0950'SIDE OF THE TANK AND A PLUMB-BOB STRING SUSPENDED OVER IT CAN BE
 PF0950'SEEN FROM SEVERAL PLACES ABOUT THE TANK.  THE BOLT IS 1 INCH IN
 PF0950'DIAMETER, WITH SLIGHTLY FLATTENED HEAD AND WITH CROSS MARKS STILL
 PF0950'VISIBLE ON IT.  IT PROJECTS ABOUT 1/4 INCH ABOVE THE ROCK AND IS IN
 PF0950'A DEPRESSION IN THE ROCK 4-1/2 FEET NEARLY DUE W FROM THE HIGHEST
 PF0950'POINT OF THE MOUNTAIN.  A U.S.G.S. BENCH MARK, E1. 6284 MARKS
 PF0950'THE HIGHEST POINT, A SHARP-TOPPED BOULDER AS DESCRIBED BY
 PF0950'C.C.Y., IN 1897.  THE TOP OF THE MOUNTAIN CONSISTS OF A MASS OF
 PF0950'BOULDERS OF VARIOUS SIZES AND AT NO PLACE IS ONE ABLE TO
 PF0950'DISTINGUISH SOLID LEDGE.  TO PRESERVE THE CENTER OF THE COPPER BOLT 3
 PF0950'STANDARD REFERENCE MARKS WERE INSTALLED, EACH ONE IN A LARGE BOULDER
 PF0950'FIRMLY IMBEDDED IN THE GROUND.  FROM THESE REFERENCE MARKS THE
 PF0950'CENTER MAY BE REPRODUCED BY THE ANGLES AND DISTANCES AS SHOWN ON THE
 PF0950'FOLLOWING SKETCH.  IT IS LIKELY THAT A MORE PERMANENT WATER
 PF0950'TANK MAY BE BUILT ON THE SUMMIT AND THE STATION MARK COVERED OR
 PF0950'DESTROYED.  IN THAT CASE REFERENCE MARK NO. 3 CAN BE OCCUPIED AS AN
 PF0950'ECCENTRIC STATION, IF IT IS NOT POSSIBLE TO REPRODUCE THE
 PF0950'CENTER AND OCCUPY IT.  A 25-FOOT TOWER ON REFERENCE MARK NO. 3
 PF0950'WOULD CLEAR THE BUILDINGS AND TANK ON THE SUMMIT.  A CLEAR VIEW FROM
 PF0950'THE GROUND AT REFERENCE MARK NO. 3 MAY BE HAD FROM ABOUT W TO
 PF0950'ENE.  THE TOP OF THE TANK GIVES A CLEAR VIEW ALL AROUND THE HORIZON.
 PF0950'THE SUMMIT OF THE MOUNTAIN IS READILY ACCESSIBLE DURING THE
 PF0950'MONTHS JUNE TO OCTOBER BY PRIVATE TOLL ROAD AND COG RAILWAY.  NO
 PF0950'TOLL WAS CHARGED FOR OUR VISIT.
 PF0950'
 PF0950'DISTANCES SHOWN WERE MEASURED WITH STEEL TAPE IN METERS.  THE ANGLES
 PF0950'SHOWN WERE MEASURED WITH A NEW ONE MINUTE TRANSIT.

 OC1373                          STATION DESCRIPTION
 OC1373
 OC1373'DESCRIBED BY COAST AND GEODETIC SURVEY 1908
 OC1373'ON THE PATUCCAWA MOUNTAIN, WHICH IS IN THE TOWNS OF NORTH
 OC1373'DEERFIELD AND NOTTINGHAM, ABOUT 800 FEET ABOVE THE LEVEL
 OC1373'OF THE SEA.  THE STATION IS ON THE HIGHEST POINT OF THE MOUNTAIN
 OC1373'AND ON A LARGE ROCK HAVING A GREATER SLOPE TO THE NW.
 OC1373'
 OC1373'THE STATION IS MARKED BY A 1/2-INCH IRON BOLT FIRMLY IMBEDDED
 OC1373'IN THE ROCK, AT THE HIGHEST POINT.
 OC1373'
 OC1373'THE NEAREST RAILROAD STATION IS LEE.  ABOUT 2 MILES FROM
 OC1373'THE STATION IS AN OLD AND LITTLE USED ROAD WHICH TURNS TO
 OC1373'THE LEFT UP A STEEP HILL FROM THE MAIN ROAD.  THIS ROAD
 OC1373'LEADS TO A FARMHOUSE JUST S OF THE MOUNTAIN.  IT IS ABOUT A
 OC1373'10-MINUTE WALK FROM THE STATION TO THE FARMHOUSE, THE FOOT
 OC1373'OF THE STEEP PART BEING ABOUT 1/4 MILE FROM THE HOUSE.  IT
 OC1373'IS BEST TO GO NE FROM THE FARMHOUSE TO A ROCK FENCE AT THE
 OC1373'FOOT OF THE STEEP PART.  FOLLOW THIS FENCE UNTIL A LITTLE
 OC1373'ROCKY GULLY IS REACHED (ABOUT 100 YARDS FROM BEGINNING OF
 OC1373'STEEP CLIMB), THEN FOLLOW UP THIS GULLY.  THIS LEADS TO THE
 OC1373'SUMMIT OF THE RIDGE ABOUT 100 YARDS TO THE EASTWARD OF
 OC1373'THE STATION.  THE FOLLOWING ARE REFERENCES--FOUR 1/2-INCH
 OC1373'DRILL HOLES ARE RESPECTIVELY, 0.51 METER FROM THE STATION,
 OC1373'N 48 DEG 40 MIN E.  0.445 METER FROM THE STATION, S 10 DEG 20 MIN E.
 OC1373'0.600 METER FROM THE STATION, N 75 DEG 20 MIN W.  0.605 METER FROM
 OC1373'THE STATION, N 70 DEG 20 MIN W.  THREE 1/2-INCH
 OC1373'BOLTS (BENT) ARE, RESPECTIVELY, 1.81 METERS FROM THE
 OC1373'STATION,  N 32 DEG 20 MIN E.  1.93 METERS FROM THE
 OC1373'STATION, S 20 DEG 00 MIN E.  3.015 METERS FROM THE
 OC1373'STATION, S 85 DEG 20 MIN W.  THE BOLT PROJECTS
 OC1373'ABOUT 4 INCHES FROM THE ROCK.

 OC1373
 OC1373'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1931 (HSS)
 OC1373'THE STATION IS ON
 OC1373'THE NORTHWESTERNMOST OF THE PATUCCAWA MOUNTAINS, CALLED
 OC1373'THE NORTH OR UPPER MOUNTAIN.  I FOUND THE IRON STATION-BOLT,
 OC1373'THE 4 DRILL HOLES AND THE 3 BENT BOLTS.  THE STATION-BOLT
 OC1373'IS BROKEN OFF FLUSH WITH THE LEDGE, HOWEVER, IT SEEMS TO BE
 OC1373'FIRMLY IN PLACE.  I FOUND 3 OTHER DRILL HOLES WHICH ARE NOT
 OC1373'MENTIONED IN THE DESCRIPTION, ALTHOUGH THEY SEEMED TO BE
 OC1373'AS OLD AS THE OTHERS.  ONE OF THESE HOLES, A SMALL ONE, IS
 OC1373'2.60 METERS FROM THE STATION, ABOUT S 17 DEG E, AND
 OC1373'MAY HAVE SERVED TO MARK THE LINE TO GUNSTOCK.  ANOTHER, IN
 OC1373'WHICH THERE ARE 3 SMALL IRON WEDGES, IS 2.25 METERS FROM THE
 OC1373'STATION, ABOUT S 73 DEG W, AND THE THIRD IS 2.51
 OC1373'METERS, ABOUT S 74 DEG W AND MAY HAVE MARKED THE LINE TO
 OC1373'AGAMENTICUS.  THESE AZIMUTHS WERE ONLY VERY ROUGHLY
 OC1373'DETERMINED AND ARE NOT AT ALL EXACT.  THE VIEW FROM THE
 OC1373'STATION IS LARGELY OBSCURED BY THE UPPER PORTIONS OF
 OC1373'NEARBY TREES, BUT LINES COULD READILY BE OPENED IN MOST
 OC1373'DIRECTIONS.
 OC1373'
 OC1373'A STEEL FIRE TOWER OF THE NEW HAMPSHIRE FORESTRY DEPARTMENT
 OC1373'IS ABOUT 1.5 MILES SE, ON THE SOUTH OR LOWER MOUNTAIN AND
 OC1373'IS AN INTERSECTION STATION OF THE GEOLOGICAL SURVEY, CALLED
 OC1373'LOOKOUT.  IT IS MORE ACCESSIBLE THAN STATION PATUCCAWA.  A
 OC1373'STATE FOREST RESERVATION COVERS MOST OF THE REGION (918
 OC1373'ACRES) AND INCLUDES BOTH THE FIRE TOWER AND STATION PATUCCAWA,
 OC1373'THE LATTER BEING NEAR THE NORTHWESTERN EDGE.
 OC1373'
 OC1373'THE MOUNTAIN CAN BEST BE REACHED FROM ROUTE 101, WHICH IS THE
 OC1373'STATE ROAD FROM PORTSMOUTH AND EXETER TO MANCHESTER.  AT A
 OC1373'POINT ABOUT 3 MILES NW OF THE VILLAGE OF RAYMOND A GOOD ROAD
 OC1373'LEADS FROM ROUTE 101 TO DEERFIELD, PASSING WITHIN ABOUT 2
 OC1373'MILES OF THE STATION.  LOCAL INFORMATION SHOULD BE OBTAINED FOR A
 OC1373'NEARER APPROACH.  THE MOUNTAIN IS LITTLE FREQUENTED AND I
 OC1373'FAILED TO FIND A TRAIL TO THE SUMMIT.

 OC1373'ETT.  FROM HERE PACK EASTERLY TO HIGHEST POINT OF RIDGE
 OC1373'AND STATION.  ABOUT 1/2 HOUR PACK.
 OC1373'
 OC1373'A 15 FOOT WOODEN STAND NOW STANDS OVER THE STATION AND SHOULD
 OC1373'BE SERVICEABLE FOR APPROXIMATELY TWO OR THREE YEARS WITH
 OC1373'MINOR REPAIR TO THE HEAD OF THE INNER STAND AND A NEW PLATFORM
 OC1373'FOR THE OUTER STAND.  VISIBILITY IS CLEAR IN MOST DIRECTIONS

 OC2415'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1953 (PT)
 OC2415'THE STATION WAS RECOVERED IN GOOD CONDITION.  THE REFERENCE
 OC2415'MARKS HAVE BEEN DESTROYED BY EXCAVATIONS ON THE S AND W SIDES
 OC2415'OF THE STATION.  THE STATION ITSELF WILL PROBABLY BE DESTROYED
 OC2415'IN THE FUTURE.
 OC2415'
 OC2415'INQUIRY FROM THE OWNERS OF THE GRAVEL PIT IN WHICH THE STATION
 OC2415'IS LOCATED ESTABLISHED THE FACT THAT THERE IS NO PLACE WHERE
 OC2415'THE STATION CAN BE SET NEARBY WHERE IT WOULD NOT BE DESTROYED
 OC2415'WITHIN THE NEXT TWO YEARS.

 OC2582'DESCRIBED BY NATIONAL GEODETIC SURVEY 1976 (JLO)
 OC2582'THE STATION IS A LARGE GREEN STANDPIPE LOCATED ABOUT
 OC2582'0.2 MILES WEST OF SOMERSWORTH ON ROCKY HILL ROAD.  THE
 OC2582'STANDPIPE IS ABOUT 40 FEET IN DIAMETER AT THE BASE
 OC2582'AND ABOUT 130 FEET HIGH.  THE POINT INTERSECTED WAS
 OC2582'A GREEN BALL AT THE TOP.  THE STANDPIPE IS OWNED BY THE
 OC2582'SOMERSWORTH WATERWORKS DEPARTMENT AND WAS BUILT IN 1971.
 OC2582'AN OLD STATION, SOMERSWORTH LARGE STANDPIPE, IS LOCATED
 OC2582'ON THE HIGHEST HILL IN SOMERSWORTH.  THE NEW STANDPIPE
 OC2582'IS ACTUALLY LARGER THAN THE OLD STATION BUT SINCE IT
 OC2582'IS 2-MILES TO THE WEST AND IS NOT ON A HILL IT SHOULD
 OC2582'NOT BE CONFUSED WITH THE OLD ONE.

 OC2485'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1928 (GCM)
 OC2485'STATION IS ON THE E END OF THE HIGHEST PART OF THE SUMMIT OF
 OC2485'STRATHAM HILL.  THIS HILL IS INCLUDED IN STRATHAM HILL PARK.
 OC2485'THE PORTSMOUTH AND EXETER ELECTRIC CAR LINE TRACK WAS TAKEN
 OC2485'UP IN 1911.  THE ORIGINAL STATION MARK, A 1/2-INCH DRILL HOLE
 OC2485'IN SOLID ROCK, PROJECTING A FEW INCHES ABOVE THE SURFACE OF
 OC2485'THE GROUND, AND WAS FOUND IN GOOD CONDITION.  THE OLD
 OC2485'SUMMER-HOUSE HAS BEEN DESTROYED, THE POST WITH DIRECTIONS HAS
 OC2485'BEEN REMOVED.  ON THE LOCATION OF THE OLD SUMMER-HOUSE, JUST
 OC2485'W OF THE STATION, IS A METAL CIRCULAR DIAL SUPPORTED ON 6
 OC2485'IRON POSTS, ESTABLISHED BY U.S. SURVEY, AUGUST, 1910.  THIS
 OC2485'DIAL GIVES ELEVATION OF POINT AS WELL AS DIRECTIONS AND
 OC2485'DISTANCES TO VARIOUS POINTS.  THE LARGE FLAGPOLE WITH TOP
 OC2485'MAST WIRE GUYS, IS IN GOOD CONDITION.  THE REFERENCE IRON
 OC2485'BOLT WAS FOUND IN GOOD CONDITION.  DISTANCES WERE
 OC2485'CHECKED.

 OC2485
 OC2485'RECOVERY NOTE BY NEW HAMPSHIRE GEODETIC SURVEY 1930
 OC2485'I VISITED THIS LOCALITY FREQUENTLY, THE LAST TIME BEING DECEMBER
 OC2485'10, 1930.  THE DRILL HOLE WHICH MARKS THE STATION IS IN GOOD
 OC2485'CONDITION, APPEARS TO HAVE BEEN UNDISTURBED, AND MAY BE EASILY
 OC2485'FOUND.  THE FLAGPOLE AND BENT BOLT REFERRED TO IN THE ORIGINAL
 OC2485'DESCRIPTION REMAIN AS STATED, BUT THE SUMMER-HOUSE WAS REMOVED
 OC2485'SOME YEARS AGO.  THERE IS, HOWEVER, A SUBSTANTIAL CAST-IRON
 OC2485'TABLE, OR DIAL, WITH THE NAMES OF NUMEROUS PROMINENT OBJECTS
 OC2485'ARRANGED RADIALLY, IN RAISED LETTERS.  THE TABLE IS ABOUT 4
 OC2485'FEET IN DIAMETER AND HAS SIX LEGS WHICH ARE SET IN SOLID
 OC2485'CONCRETE BASE.  THE CENTER OF THE TABLE IS ABOUT 34.4 FEET
 OC2485'FROM THE STATION AND BEARS ABOUT 6-1/4 DEG W OF THE
 OC2485'FLAGPOLE, OR ABOUT S 72 DEG 40 MIN E, VIEWED FROM
 OC2485'THE STATION.
 OC2485'
 OC2485'STRATHAM HILL, ON WHICH THE STATION IS LOCATED, HAS BEEN A
 OC2485'PUBLIC PARK, CALLED STRATHAM HILL PARK, SINCE 1906.  THE
 OC2485'TOP OF THE HILL IS OPEN, WITH ONLY A FEW SMALL TREES AND BUSHES.

 OC2485
 OC2485'RECOVERY NOTE BY NEW HAMPSHIRE GEODETIC SURVEY 1931
 OC2485'A SUBSTANTIAL STEEL FIRE-TOWER IS BEING BUILT NEAR THE STATION,
 OC2485'FOR THE NEW HAMPSHIRE FORESTRY DEPARTMENT.  THE TOWER IS ABOUT
 OC2485'20 FEET SQUARE AT THE BASE, AND THE CENTER OF THE SQUARE IS
 OC2485'ABOUT 18.4 FEET FROM THE STATION, IN AZIMUTH ABOUT 315 DEG
 OC2485'35 MIN.  THE TOWER IS TO BE ABOUT 65 FEET HIGH, I AM TOLD,
 OC2485'AND IT WILL BE A PROMINENT LANDMARK.
 OC2485'
 OC2485'IN OTHER RESPECTS THE STATION APPEARED TO BE IN THE SAME
 OC2485'CONDITION AS WHEN I REPORTED ON IT IN 1930, AND I FOUND
 OC2485'NOTHING TO INDICATE THAT IT HAD BEEN DISTURBED IN THE PROCESS
 OC2485'OF INSTALLING THE FOUNDATIONS FOR THE TOWER.

 MY3800'IS A U.S.G.S. TABLET, IN A CONCRETE POST, WHICH WAS PLACED
 MY3800'BY C.B. KENDALL, IN 1931.  ACCORDING TO THE FIRE WATCHMAN
 MY3800'MR. KENDALL FAILED TO FIND THE STATION OF 1848, ALTHOUGH THEY
 MY3800'DID CONSIDERABLE DIGGING.  U.S.G.S. BULLETIN 216 STATES THAT THE
 MY3800'STATION WAS USED BY G.T. HAWKINS IN 1903.  BUT IN 1925 R.M.
 MY3800'WILSON, OF THE U.S.G.S. FAILED TO FIND THE STATION WHEN HE
 MY3800'DETERMINED THE POSITION OF THE FIRE TOWER, CALLING IT
 MY3800'UNCANOONUC TOWER.  THE TYPEWRITTEN DESCRIPTION OF THE LATTER
 MY3800'STATION IS IN PART AS FOLLOWS--THE STATION WAS ORIGINALLY
 MY3800'ESTABLISHED BY THE U.S.C. AND G.S. AND MARKED BY A HOLE
 MY3800'DRILLED IN SOLID ROCK.  THIS MARK COULD NOT BE FOUND IN
 MY3800'1925.  A HIGH STEEL FIRE LOOKOUT TOWER HAS BEEN ERECTED ON THE
 MY3800'SUMMIT AND THE CENTER OF THIS TOWER MARKS THE LOCATION OF
 MY3800'1925.  IT IS NOT POSSIBLE TO SEE OUT FROM THE GROUND.  THE OLD
 MY3800'COAST SURVEY MARK IS PROBABLY ABOUT 2 FEET S AND 5 FEET W OF
 MY3800'CENTER OF TOWER.
 MY3800'
 MY3800'I VISITED UNCANOONUC MOUNTAIN (NOW USUALLY THUS SPELLED) TWICE
 MY3800'DURING THE FALL OF 1932, BUT FAILED TO FIND THE OLD STATION.
 MY3800'IT MAY STILL EXIST, HOWEVER, UNDER THE SURFACE, UNLESS IT WAS
 MY3800'DESTROYED OR COVERED UP DURING THE BUILDING OF THE FOUNDATIONS
 MY3800'OF THE TOWER.
 MY3800'
 MY3800'THE VIEW FROM THE GROUND IS MOSTLY OBSTRUCTED BY TREES, BUT IS
 MY3800'CLEAR IN ALL DIRECTIONS FROM THE OBSERVATION ROOM OF THE TOWER.

 MY3800'THE STATION MAY BE BEST REACHED FROM MANCHESTER, NEW HAMPSHIRE
 MY3800'VIA HIGHWAY NO. 114.  AT A PLACE CALLED SHIRLEY STATION, ABOUT
 MY3800'A MILE E OF THE VILLAGE OF GOFFSTOWN, A ROAD MARKED BY SIGNS
 MY3800'LEADS S, ABOUT 2.3 MILES, TO THE BASE OF THE MOUNTAIN.  FROM
 MY3800'THERE AN ELECTRIC CABLE RAILWAY RUNS TO WITHIN A SHORT DISTANCE
 MY3800'OF THE STATION.  THE RAILWAY IS OPERATED DURING THE SUMMER
 MY3800'MONTHS (MAY 30 TO ABOUT NOVEMBER 1 IN 1932) AND THE TRIP TAKES
 MY3800'BETWEEN 5 AND 10 MINUTES.  THE RAILWAY AND A SHORT PIECE OF
 MY3800'ROAD LEADING TO IT ARE NOT SHOWN ON THE U.S.G.S. MILFORD SHEET
 MY3800'(EDITION OF 1906) WHICH COVERS THE REGION.  THERE IS A
 MY3800'TRAIL NEAR THE RAILWAY.  THE ROAD SHOWN ON THE MILFORD
 MY3800'SHEET, ON THE WESTERLY SIDE OF THE MOUNTAIN, WAS ONCE A TOLL
 MY3800'ROAD, BUT IS SAID TO BE NO LONGER PASSABLE FOR VEHICLES.

 MY3800
 MY3800'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1933 (HSS)
 MY3800'ON OCTOBER 4, 1933, I FOUND A
 MY3800'DRILL HOLE WHICH I THINK IS THE ONE WHICH MARKS THIS STATION,
 MY3800'ALTHOUGH IT SEEMS IMPOSSIBLE TO MAKE A POSITIVE IDENTIFICATION,
 MY3800'AS I HAVE BEEN UNABLE TO FIND ANY MENTION OF ANY REFERENCE MARKS,
 MY3800'EITHER IN THE ORIGINAL DESCRIPTION OR ELSEWHERE.  IN THE
 MY3800'DESCRIPTION OF THE U.S.G.S. STATION UNCANOONUC TOWER, OF 1925, IT
 MY3800'IS STATED THAT THE OLD COAST SURVEY MARK IS PROBABLY ABOUT 2
 MY3800'FEET S AND 5 FEET W OF CENTER OF TOWER.  I BEGAN TO DIG AT
 MY3800'ABOUT THAT POINT AND AFTER UNCOVERING A NUMBER OF SQUARE
 MY3800'FEET OF THE LEDGE AND PROBING CAREFULLY WHERE IT WAS DIFFICULT
 MY3800'TO REMOVE ALL THE MOIST SOIL FROM THE VERY ROUGH SURFACE OF
 MY3800'THE LEDGE, I FOUND THAT ABOVE-MENTIONED DRILL HOLE, ABOUT 2
 MY3800'FEET OR SO FROM THE POSITION GIVEN IN THE U.S.G.S.
 MY3800'DESCRIPTION.  THE AGREEMENT MAY BE EVEN CLOSER, HOWEVER, AS I
 MY3800'WORKED FROM THE CENTER OF THE SQUARE FORMED BY THE LEGS OF THE
 MY3800'TOWER AND I DID NOT ATTEMPT TO PLUMB DOWN FROM THE TOP OF THE
 MY3800'TOWER.  THE DRILL HOLE IS ONLY 1/2 TO 3/4 INCH DEEP, BUT IS
 MY3800'DEFINITELY RECOGNIZABLE AS A DRILL HOLE, AND IT SEEMS
 MY3800'PROBABLE THAT A PIECE OF THE LEDGE HAS BEEN BROKEN OFF,
 MY3800'LEAVING ONLY THE LOWER PART OF THE HOLE.  THE LEDGE IS
 MY3800'COVERED WITH ABOUT 9 OR 10 INCHES OF SOIL AT THIS POINT.
 MY3800'
 MY3800'THE DRILL HOLE IS 4.72 FEET (HORIZONTALLY) ABOUT 4-3/4 DEG N
 MY3800'OF W FROM THE U.S.G.S. TABLET (UNSTAMPED) WHICH WAS SET IN 1931.
 MY3800'THIS TABLET IS ABOUT 3 INCHES S OF THE INTERSECTION OF THE
 MY3800'DIAGONALS OF THE SQUARE FORMED BY THE TOWER LEGS.

 MY3800'DUG TO BEDROCK WHICH SHOULD HAVE INCLUDED THE STATION WITH AN
 MY3800'UNCERTAINTY OF ABOUT +/- 6 INCHES.
 MY3800'
 MY3800'THE BEDROCK WAS IRREGULAR BUT NO SIGN OF A DRILL HOLE WAS FOUND. DUE
 MY3800'TO THE UNCERTAINTIES IN THE GEODETIC LOCATIONS, THE STATION MAY STILL
 MY3800'EXIST UNDERGROUND BEYOND THE RANGE OF OUR SEARCH.
