Found this today on the curb on Highland Ave.

Seems like an odd place for a BM.

I found another benchmark very near this one two days ago. Didn't realize there was another one so close. Came back today and found this one today. Had to brush aside lots of pine needles to see it. Returned the cover and went on with my walk.

Recovered in good condition after checking in w/ homeowner..

I found RM3 just by looking around, and it pointed to the yard. I walked to a small depression, kicked off some old grass and found it.

Greetings Geocachers/Benchmarkers,

I found this benchmark near 222 Highland Avenue in Hanover, PA with no difficulty, as pictured and reported by embra. Although a bit covered by debris, and subsurface, the disk is in good condition exactly where it’s supposed to be. Coordinates and directions are adequate for recovery.

Happy Benchmarking,
Ghosthunter

I'm a little surprised this one wasn't reported here with the RM3 being such a short distance away. Description is still adequate for recovery; disk is in good shape. Easiest to find RM3 first.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in January 1992.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
