Was out on an evening walk and came across this. Didn't spend time to find the nearby caches as there was a lot of traffic. Will return at a later date

Found it in good condition while geocaching. Do not touch a metal object that has been in the direct Tucson sun! Almost as painful and getting poked by a cholla .... almost.

Found in good shape

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in August 1993.
  • The orthometric height was determined by GPS observations and a high-resolution geoid model.
  • 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.
