 TZ0982'DESCRIBED BY INTER-AMERICAN GEODETIC SURVEY 2000 (JE)
 TZ0982'THIS STATION IS FOUND AT THE PEAK OF THE MOUNTAIN LAS MOCHAS.
 TZ0982'LAS MOCHAS IS ABOUT 75 KM SOUTH OF SAN PEDRO SULA AND 9 KM WEST
 TZ0982'OF LAGO DE YOJOA. THE NEAREST TOWN IS HORCONCITOS WHICH
 TZ0982'IS SOUTHEAST AND ABOUT 2 KM FROM LAS MOCHAS.
 TZ0982'
 TZ0982'FROM TEGUCIGALPA GO NORTH ON CA5 FOR APPROXIMATELY 120 KM OR
 TZ0982'UNTIL YOU REACH THE TURN OFF FOR HIGHWAY 20 AT PITO SOLO.
 TZ0982'TAKE 20 NORTH TOWARDS SANTA BARBARA. AT ABOUT 23 KM, BETWEEN LA
 TZ0982'PIMIENTA AND EL MOGOTE, THERE IS A ROAD TO HORCONCITOS (IT IS
 TZ0982'MARKED). THE TURN WILL BE TO THE RIGHT AND THE ROAD GOES
 TZ0982'NORTH TO HORCONCITOS. FOLLOW THIS ROAD NORTH APPROX. 7 KM TO A ROAD
 TZ0982'(CERRO DE LAS MOCHAS) TO THE LEFT THAT LEADS TO THE LOS
 TZ0982'HORCONCITOS. AT HORCONCITOS YOU MAY WANT TO FIND A GUIDE. WE
 TZ0982'FOLLOWED (TO THE RIGHT) LEADING UP THE MOUNTIAN. WHEN WE
 TZ0982'COULD NOT DRIVE ANY FURTHER WE MET A GUIDE AND HE LEAD US BY FOOT
 TZ0982'TO THE TOP OF THE MOUNTAIN TO THE SITE. THIS WAS A STRENUOUS 1.5
 TZ0982'HOUR CLIMB.
 TZ0982'
 TZ0982'OUR GUIDE LIVED AT THE END OF THE ROAD. HIS NAME WAS LUCAS
 TZ0982'DOMINGEZ BANDALES (SEE NOTES). HE REQUESTED 75 LIMPERAS FOR
 TZ0982'HIS SERVICES BUT I PAID HIM 100 (NO CHANGE).
 TZ0982'
 TZ0982'NOTE- I DID NOT FIND ANY LODGING IN THIS AREA. THERE ARE A
 TZ0982'FEW GOOD SIZE TOWNS NEARBY BUT YOU WILL HAVE TO LOOK. MAYBE LODGING IF
 TZ0982'YOU ASK AROUND IN HORCONCITOS.
 TZ0982'
 TZ0982'YOU WILL NOT WANT TO MAKE THIS TRIP MANY TIMES. IT MAY BE
 TZ0982'MORE CONVENIENT TO CAMP AT THE SITE. BRING PLENTY OF WATER BECAUSE
 TZ0982'THIS PLACE IS ISOLATED.
