Recovered in good condition - hardest part was finding someone to get permission to search. It doesn't appear that cattle are currently running in this field.

RM1 & RM2 were recovered in good condition also...

Greetings Geocachers/Benchmarkers,

We found this Triangulation Station disk with no difficulty. It’s as described, exactly where it’s supposed to be, in a pasture with curious cows, SW of Shippensburg, PA in Franklin Co. Also, we recovered RM 1 and RM2. All in good shape. Coordinates and directions are adequate for recovery. Thanks to gnbrotz for his help with recovery of these marks. A fun recovery.

Happy Benchmarking,
Ghosthunter
Gettysburg, PA

I recovered this mark, as well as RM1 & RM2 with my friend Ghosthunter. Pacing of RM distances was a bit tricky with all the cow manure, and the heifers seemed quite interested in what we were doing.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in April 1998.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • 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.
