Found this with Tprints while out geocaching.

Out caching and waymarking in Jamestown. Stopped to find this benchmark too. Started out on wrong elevation but soon corrected that and found the marker.

Found this one while working. It is in good shape, but the railing along the wall is NOT! I went to lean on the railing and bend down for a closer look and a piece broke off so be carefull if you atempt to find this one. I got WGS 84 coordinates for this point that might be helpfull in locating this benchmark.
N 42 05.646
E079 14.517
Good luck!

You'd think I've have found it more quickly... there was orange tape marking the spot!

On top of concrete retaining wall across tracks from parking lot of Jamestown Post Journal. Someone had spray painted it light yellow, making it difficult to read.

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.
