Very easy find with the snow all gone. What a cold wind off the lake over here today. took picture and drove on to other benchmarks. Recovered in good condition today.

It was not hard to find at this time of year. The grass and weeds were gone.

The boulder that is described is pretty well buried. I expected to find a large rock but the ground and weeds hide this disk.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in July 1997.
  • The orthometric height was determined by GPS observations and a high-resolution geoid model.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • The geoid height was determined by GEOID99.
