Documented History (by the NGS)

01/01/1839 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1839 (EB) STATION IS ON THE SUMMIT OF SHERMAN HILL, ABOUT 4-1/2 MILES N OF WAKEFIELD, AND 1-3/4 MILES NNE OF KINGSTON. THE STATION IS MARKED BY A BURIED STONE CONE.
01/01/1935 by RIGS (SEE DESCRIPTION)
RECOVERY NOTE BY RHODE ISLAND GEODETIC SURVEY 1935 SHERMAN HILL IS ABOUT 1/8 MILE N OF THE SHERMAN HOMESTEAD, WHICH IS AT THE END OF THE ROAD WHICH LEADS N FROM THE VILLAGE OF KINGSTON, AND IS 1.6 MILES THEREFROM. MR. SHERMAN, THE PRESENT OWNER OF THE FARM, TELLS ME THAT IN 1881, WHEN HE WAS CARTING AWAY SAND, THE STONEWARE POT WITHOUT ANY BOTTOM FELL OUT AND WAS BROKEN. HE SAYS HE TOLD THIS TO R.U. GOODE IN 1888 AT THE TIME THAT MR. GOODE MADE OBSERVATIONS FROM A TOWER WHICH HE ERECTED ON THIS HILL. THE POINT USED BY THE ENGINEERS IN 1888, MR. SHERMAN SAID, WAS ABOUT 10 FEET SW OF WHERE HE HAD DUG THE SAND. AT THE SPOT WHICH HE POINTED OUT, I DUG IN THE HOPE OF FINDING SOME MARK LEFT BY MR. GOODE, BUT FOUND NOTHING. NEITHER COULD I FIND ANY MARK CUT INTO ANY OF THE BOULDERS IN THE VICINITY. IT WAS PROBABLY A U.S. GEOLOGICAL SURVEY PARTY WHICH HE RECALLED. MR. SHERMAN ALSO REMEMBERS GOVERNMENT SURVEYORS (PROBABLY U.S. ENGINEERS) MAKING OBSERVATIONS ABOUT 20 YEARS AGO. FOUND A POST SURROUNDED BY STONES WHICH MIGHT BE MISTAKEN FOR A STATION MARK. MR. SHERMAN SAYS IT IS THE STUMP OF A FLAGPOLE HE FORMERLY HAD ON THIS HILL.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in August 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.
