Discoverd this one while visiting Falcon Hill. What a surprise. The last benchmark I stumbled across was in Papago Park.

Stumbled over this while searching for Falcon Hill Cache.

This is our very first Benchmark! Marker was in excellent condition, stumbled across this one while searching for the Falcon Hill Cache.

Found this when I hid the nearby Falcon Hill cache! Didn't realize I had forgotten to log my find!

The big splashes of paint from recent use of the marker was a big tip-off to its location. One of the more battered ones we've seen.

Just happened by this as we were looking for the Falcon View Cache. So snapped a few pictures of it. Will post the pictues in a few.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in September 1992.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • 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.
