Found the disk stem with my dad.

Found just the stem and the mounting concrete. As per the guidance document located on geocaching (3/30/2010), I am reporting this as found. You can still see the letter "K" from the disk designation "K 33".

N 39 28.043 W080 08.854 with 30' accuracy.

The disk has been broken off the concrete post. Only the stem remains. The stem can still be used for surveying.

Another find will out with my son. Marker is pretty much gone except for the center,looks as though someone pried it off.

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 1992. * This is a POSTED BENCH MARK height. Code A indicates a distribution rate of 0.0 thru 1.0 mm/km.
  • 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.
