Found this because it had been excivated at some point. Also a paint mark on the edge of the road pointed toward it.

Yeah...did this with Snoscootr...looked at it for a second, but I was watching for muggles...I prefer these over caches, they're easier to find ^.^

Found in ~10 minutes. Was very very close to cordinates. Sunk in ground ~4 inches, had a few leaves in hole but all suggested landmarks made this find pretty easy!

Looked very carefully for about 15 minutes. No sign. Lots of construction around here in the last 10 years. May be destroyed.

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.
