Found while doing Barbers Pond Multi Cache. Our first Benchmark. :)

Found with GeeksLady while trying to find 2nd part of a cache

Found while searching for part 2 of "let's go fishing"

Found this one right near the final for "Lets Go Fishing" Multi

My first benchmark!!

found while out cache ....this was at the top of the concrete tunnel in great condition njdc24/kmt,nj

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • 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.
