Benchmark D328 recovered in good condition. It was found as described with the following exception:

The 6th pole northwest of MP 284 has been cut down. (The poles on the west side of the railroad tracks have been cut down and replaced by poles on the east side of the tracks.) This mark is now approximately 110 feet southwest of the 8th pole northwest of MP 284.

DESCRIBED BY NATIONAL GEODETIC SURVEY 1949 6.7 MI NW FROM NIPTON. 6.7 MILES NORTHWEST ALONG THE UNION PACIFIC RAILROAD FROM THE STATION AT NIPTON, 219 1/2 FEET SOUTHEAST OF A DESERT ONE MILE SIGN, 15 FEET SOUTHWEST OF THE 6TH POLE NORTHWEST OF MILEPOLE 284, 60.0 FEET SOUTHWEST OF THE SOUTHWEST RAIL, 7 FEET NORTHEAST OF THE CENTER LINE OF A DIM TRACK ROAD, ABOUT 8 FEET LOWER THAN THE TRACK, 2.0 FEET NORTHWEST OF A WITNESS POST, AND SET IN THE TOP OF A CONCRETE POST PROJECTING 0.4 FOOT ABOVE 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.
