Documented History (by the NGS)

01/01/1933 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1933 7.6 MI N FROM WATSON. ABOUT 7.6 MILES NORTH ALONG THE WATSON-JENSEN ROAD FROM WATSON, UINTAH COUNTY, ABOUT 3.4 MILES SOUTHEAST OF THE WHITE RIVER TOLL BRIDGE, AT THE NORTHEAST BASE OF A HILL MARKED BY A PROMINENT ROCK OUTCROP ON THE SOUTH SIDE OF THE PEAK, AT THE SOUTHWEST RIM OF A SMALL CANYON RUNNING NORTHWEST, AND ABOUT 60 FEET NORTHEAST OF THE CENTER LINE OF THE ROAD. A STANDARD DISK, STAMPED 5301.111 L 26 1933 AND SET IN THE TOP OF A CONCRETE POST.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (G = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
