Found it while geocaching in the area.

I am back after a hiatus. Sorry for the delay and repetitions in logging. Found this in good shape with Grand High Pobah and had a great time.

Another Bench find while Geocaching.

I remember this one clearly as the path to it was between a large puddle and the barbed-wire fence.

Documented History (by the NGS)

01/01/1935 by CGS (MONUMENTED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1935 17 MI N FROM FORDER. 17.0 MI N OF FORDER P.O. ALONG ST HWY 71, ABOUT 32 FT. S. OF THE CENTER LINE OF A CROSSROADS, ABOUT 50 FT. W. OF THE CENTER LINE OF THE HWY. AND 2 FT. S.W. OF A GATE POST.

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.
