found it

Recovered in good condition - the land is still slated to be sold for development....it would be nice if this little knoll remains intact - very nice small woods.

After obtaining permission to search, I back-tracked 250' or so to a small gravel road that runs NW & then heads NE toward a cell tower for about .1 mi. I parked at the end of the gravel road & continued roughly N for .15 mi.

RM 2 was visible first, the rock outcroping clearly exposed & 4 feet W of a 20-inch tree. I walked over to the area of the station & looked a few feet past & spied RM 1, also clearly exposed. The main station was covered by a layer of pine needles, which were easily brushed away - it is 3 feet NE of an 18-inch pine.

Didn't need my measuring tape or metal detector, but was a fun recovery - just for the view!

Greetings Geocachers/Benchmarkers,

We found this Triangulation Station disk with no difficulty. It’s as described, exactly where it’s supposed to be, at the top of a hill S 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,

Found the station mark and both RMs as described. Property has recently been sold by Paul Witter (great-grandson of previously mentioned Roy E. Witter) to developers. Paul states that he will maintain posession of property for approx. 1 more year before development begins.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in April 1998.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
