Found in poor condition as indicated in photos. Some idiot chiseled it off leaving only the stem.

Every time I encounter this kind of senseless destruction it angers me.

I found the station in good condition, as described. My photos are essentially the same as Team Tuxuwuxa's.

Found on headwall on original roadbed. Coordinates are quite a bit off, as usual. Correct ones are N 35 02.716, W 106 23.012.

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.
