We were lucky enough to be with our Grandpa,GEO*TRAILBLAZER 1 and our Grandma TIGGR when they recovered this mark.

THIS ONE WAS ON THE ROUTE OF OUR 6000 MILE JOURNEY ACROSS THE USA SO WE STOPPED AND GOT IT.

ANOTHER GREAT PLACE JUST SOUTH OF THE GEO*CENTER OF THE NATION.

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.
