Documented History (by the NGS)

1/1/1870 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1870 (GAF) ON A HILL ON THE E SIDE OF SOMES SOUNDS, ABOUT 1 MILE ABOVE SARGENT POINT AND THE SAME DISTANCE E OF SQUANTUM POINT. THE STATION IS ON A LEDGE IN MARTIN RICHARDSONS PASTURE AND JUST TO THE SE OF HIS HOUSE, AND 11 FEET SE OF A LARGE BOULDER. TO THE EASTWARD THE LAND IS MUCH HIGHER. 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 MARK RECOVERED AS DESCRIBED ON A HILL ON THE E SIDE OF SOME SOUND AT ITS NORTHERN END 4-1/4 MILES WSW OF BAR HARBOR. STATION AND REFERENCE MARKS ARE STANDARD BRONZE DISKS WEDGED IN DRILL HOLES IN OUTCROPPING BEDROCK. THE STATION MARK, IS 90 FEET WSW OF MID-TANGENT OF S CURVE IN WOODS ROAD. IT IS 13 FEET SSW OF CENTER OF A 5-FOOT HIGH BOULDER AND 20.23 FEET ESE OF MIDDLE WEDGE OF THREE WEDGES AND BUSHINGS IN LEDGE. REFERENCE MARK NO. 1 IS 45.59 FEET SW OF STATION. IT IS 3-1/2 FEET E OF A SHEER W FACE OF LEDGE, AND 5-1/2 FEET S OF A SHEER 2-FOOT N FACE. REFERENCE MARK NO. 2, IS 26.24 FEET NW OF STATION IN A LEDGE WITH A 5-FOOT ON SIDE SQUARE NOTCH AND WHICH HAS A SQUARE 2-1/2 FOOT BLOCK OF ROCK AT NOTCH.

Control Text

  • 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.
