PG2096.The horizontal coordinates were established by classical geodetic methods
PG2096.and adjusted by the National Geodetic Survey in January 1999.
PG2096
PG2096.The NAVD 88 height was computed by applying the VERTCON shift value to
PG2096.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
PG2096
PG2096.Significant digits in the geoid height do not necessarily reflect accuracy.

PG2096 STATION DESCRIPTION
PG2096
PG2096'DESCRIBED BY COAST AND GEODETIC SURVEY 1942 (FBQ)
PG2096'THE STATION IS ABOUT 12-1/2 MILES SSE OF LAKE PLACID, ON THE
PG2096'SUMMIT OF MT. MARCY, THE HIGHEST MOUNTAIN IN THE ADIRONDACK RANGE,
PG2096'AND ON THE PROPERTY OF THE STATE OF NEW YORK. IT IS ON THE VERY
PG2096'HIGHEST PART OF THE E-W RIDGE WHICH FORMS THE SUMMIT OF THE
PG2096'MOUNTAIN. IT IS STAMPED MARCY 1942.
PG2096'
PG2096'STATION AND REFERENCE MARK NO.2 ARE BRONZE DISKS SET IN DRILL
PG2096'HOLES IN OUTCROPPING BEDROCK.
PG2096'
PG2096'REFERENCE MARK NO.1, WHICH IS A COPPER BOLT SET IN A DRILL HOLE
PG2096'IN BEDROCK, IS NE OF THE STATION. IT IS AN OLD ADIRONDACK
PG2096'SURVEY MARK, BUT IS NOT STAMPED.
PG2096'
PG2096'REFERENCE MARK NO.2 IS NW OF THE STATION IN THE BEDROCK WHICH
PG2096'CAPS THE SUMMIT OF THE PEAK. IT IS STAMPED MARCY NO. 2 1942.
PG2096'
PG2096'STATION HEART, THE AZIMUTH MARK, A BRONZE DISK SET IN A DRILL
PG2096'HOLE IN OUTCROPPING BEDROCK, IS ABOUT 5 MILES NNW OF THE
PG2096'STATION, NEAR THE ADIRONDACK LODGE AT THE NW EDGE OF THE BASE OF
PG2096'MT. MARCY. IT IS ABOUT 10 FEET NE OF THE CENTER LINE OF THE ROAD
PG2096'LEADING PAST THE SMALL TRADING POST BUILDING, AND 60 FEET SE OF
PG2096'THE SE CORNER OF THE TRADING POST. IT IS STAMPED HEART 1942
PG2096'AND IS FLUSH WITH THE SURFACE OF THE GROUND.
PG2096'
PG2096'TO REACH THE STATION FROM THE JUNCTION OF NEW YORK HIGHWAYS
PG2096'86 AND 86A IN LAKE PLACID GO S AND E ON HIGHWAY 86A FOR 3.25
PG2096'MILES AND TURN RIGHT, S, ON A PAVED SIDE ROAD. GO 1.55 MILES TO
PG2096'THE END OF THE HARD SURFACE AND CONTINUE STRAIGHT AHEAD, S. GO
PG2096'2.3 MILES AND TURN LEFT ON A T-ROAD.* GO 1.0 MILE AND PASS THRU
PG2096'A LOCKED GATE (CONSERVATION DEPARTMENT KEY). CONTINUE SOUTHERLY
PG2096'ON THIS ROAD FOLLOWING THE SIGNS TO MARCY DAM AND MARCY SKI
PG2096'TRAIL FOR 2.0 MILES TO MARCY DAM AND THE FOOT TRAIL TO THE
PG2096'SUMMIT OF MT. MARCY. FOLLOW THE BLUE TRAIL MARKERS TO THE
PG2096'SUMMIT OF THE MOUNTAIN AND THE STATION. IT IS A 4.6-MILE
PG2096'PACK.
PG2096'
PG2096'*TO REACH THE AZIMUTH MARK FROM THIS T-ROAD KEEP STRAIGHT
PG2096'AHEAD, SOUTHERLY, TO THE ADIRONDACK LODGE AND THE MARK.
PG2096'
PG2096'A 25-FOOT SIGNAL AT SENTINEL IS VISIBLE AT 4 FEET. 4-FOOT
PG2096'SIGNALS AT HEART, JUMP, CASCADE, HURRICANE, GIANT, DIX, AND
PG2096'BOREAS ARE VISIBLE AT 4 FEET.

PG2096 STATION RECOVERY (1975)
PG2096
PG2096'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1975 (RFH)
PG2096'STATION DISK HAS BEEN PRIED OFF, BUT THE STEM REMAINS IN THE DRILL
PG2096'HOLE. RM 1 COPPER BOLT HAS BEEN REMOVED, BUT THE DRILL HOLE WAS
PG2096'RECOVERED. RM 2 WAS RECOVERED IN GOOD CONDITION. STATION HEART,
PG2096'USED AS THE AZIMUTH MARK, IS IN GOOD CONDITION. VIEW IS OPEN IN
PG2096'ALL DIRECTIONS FROM STATION. DISTANCE WAS CHECKED FROM REFERENCE
PG2096'MARKS TO CONFIRM THE STATION MARK STEM.
PG2096'
PG2096'STATION IS LOCATED ON THE HIGHEST POINT OF MT. MARCY, ON A LARGE
PG2096'BEDROCK FORMATION ABOUT 40 FEET IN DIAMETER, AND IS MARKED BY THE
PG2096'STEM OF THE ORIGINAL BRONZE DISK.
PG2096'
PG2096'REFERENCE MARK NUMBER ONE IS A DRILL HOLE AT THE NORTHEAST END OF
PG2096'THE ROCK FORMATION.
PG2096'
PG2096'REFERENCE MARK NUMBER TWO IS A STANDARD DISK STAMPED MARCY NO 2
PG2096'1942, CEMENTED IN A DRILL HOLE ALONG THE WESTERN EDGE OF THE ROCK
PG2096'FORMATION.
PG2096'
PG2096'STATION HEART (AZIMUTH MARK) IS A STANDARD STATION DISK STAMPED
PG2096'HEART 1942, CEMENTED IN A DRILL HOLE IN A 1-1/2 X 3-FOOT BOULDER
PG2096'PROJECTING 1 INCH FROM GROUND. IT IS LOCATED IN THE NORTH END OF
PG2096'THE DIRT PARKING AREA AT THE ADIRONDACK CLUB, 178.4 FEET NORTHWEST
PG2096'OF THE NORTHWEST CORNER OF A SMALL TRADING POST BUILDING, 60.5
PG2096'FEET EAST-SOUTHEAST OF A GAS PUMP, 38.5 FEET WEST OF NORTH END OF
PG2096'A 1-RAIL FENCE, AND 50 FEET SOUTH OF WHERE THE ROAD GOES DOWN
PG2096'TO LEFT INTO TIMBER FROM NORTH END OF THE PARKING AREA.
PG2096'
PG2096'TO REACH STATION FROM THE POST OFFICE IN LAKE PLACID, GO EASTERLY
PG2096'ON NY RTE. 73 FOR 3.8 MILES TO A T-ROAD RIGHT AT SIGN MT
PG2096'MARCY. TURN RIGHT AND FOLLOW MACADAM ROAD SOUTH FOR 4.8 MILES
PG2096'TO A FORK. TAKE LEFT FORK STRAIGHT AHEAD THROUGH GATE AND GO
PG2096'0.1 MILE TO THE ADIRONDACK CLUB TRADING POST BUILDING, AND
PG2096'STATION HEART. FROM HERE PACK SOUTHERLY ON WELL-MARKED TRAIL
PG2096'FOR ABOUT 7 MILES TO SUMMIT OF MT. MARCY AND STATION.
