Documented History (by the NGS)

1/1/1936 by CGS (MONUMENTED)
1/1/1959 by NGS (GOOD)
DESCRIBED BY NATIONAL GEODETIC SURVEY 1959 27.1 MI E FROM HOLBROOK. 27.1 MILES NORTH AND EAST ALONG U.S. HIGHWAY 66 FROM THE POST OFFICE AT HOLBROOK, 0.65 MILE EAST OF THE OVERPASS FOR THE PAINTED DESERT, UNTIL REACHING A HIGHWAY SAND STOCKPILE, THENCE NORTH ABOUT 0.7 MILE FOLLOWING A DIM ROAD, 55.6 FEET SOUTH OF THE WITNESS POST, SET IN THE TOP OF A 12 INCH SQUARE CONCRETE POST THAT PROJECTS 1 INCH.

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.
