|DESCRIBED BY COAST AND GEODETIC SURVEY 1870 (GAF)
ON THE MOUNTAIN OF THAT NAME, LOCATED ON THE E SIDE OF SOMES SOUND AND ABOUT HALFWAY UP.
THE STATION IS ON A RIDGE NEAR THE CENTER OF THE MOUNTAIN AND ABOUT 100 YARDS W OF THE HIGHEST PEAK. A SHORT DISTANCE TO THE SOUTHWARD OF THE STATION, THERE IS A LARGE BOULDER CLEFT IN THE MIDDLE AND ON THE NEXT PEAK THERE IS A LARGE PILE OF ROCKS. THE STATION MARK IS A COPPER BOLT SET IN A HOLE IN A ROCK.
|1/1/1934 by CGS (SEE DESCRIPTION)
|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1934 (KGC)
STATION RECOVERED AS DESCRIBED.
THE ORIGINAL COPPER BOLT WAS LEFT IN PLACE AS THE STATION MARK AND 2 REFERENCE MARKS, STANDARD BRONZE DISKS WEDGED IN DRILL HOLES IN OUTCROPPING BEDROCK, WERE INSTALLED.

|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1944 (FLP)
STATION AND REFERENCE MARKS RECOVERED IN GOOD CONDITION AS DESCRIBED BY K.G.C. IN 1934. DISTANCE TO REFERENCE MARKS WERE CHECKED AND THE FOLLOWING DISTANCES WERE OBTAINED. REFERENCE MARK 1 IS 3.080 METERS AND REFERENCE MARK 2 IS 4.895 METERS. THE DISTANCES GIVEN IN 1934 APPEAR TO BE THE SLOPE DISTANCE.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in March 1998.
- The orthometric height was scaled from a topographic map.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
