I saw this benchmark while cleaning up the nearby trail during the Rock Island CITO event.

Out for a day of geocaching. Had to stop for a few benchmarks along the way.

Found this on our way into Colorado Springs. Surprised this one is still untouched.

Found in good condition as described.

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.
