BamBam noticed this on the way back to the truck after finding "Look Out". As previously described, the disk is in good condition. We didn't have a camera to photograph it, but the coords for it are N 31 05.839 W 086 33.329

Appears to be in good condition. A little chunk of the cement has broken off, but the disc is good to go.

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1992.
  • The orthometric height was scaled from a topographic map.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
