DESCRIBED BY US GEOLOGICAL SURVEY 1968 FROM WUPATKI NATIONAL MONUMENT VISITORS CENTER LOCATED 23.8 MILES SOUTH ALONG U.S. HIGHWAY 89 FROM THE SUSPENSION BRIDGE AT CAMERON ARIZONA AND 13.6 MILES EAST ALONG THE PARK SERVICE ROAD, PROCEED 0.4 MILES SOUTHEAST ALONG THE PARK SERVICE ROAD TO A T-ROAD NORTH, THENCE 1 MILE NORTHEAST ALONG A DIRT ROAD, 88 FEET SOUTH OF THE ROAD, 10 FEET NORTH OF A WITNESS POST. A COPPER-CLAD STEEL ROD ENCASED IN A PIPE FLUSH WITH THE GROUND.

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 1992. * This is a POSTED BENCH MARK height. Code A indicates a distribution rate of 0.0 thru 1.0 mm/km.
  • 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.
