Found the station and RM1, but couldn't remember which direction RM2 was supposed to be. I searched around for a while without luck. I made a very sorry attempt to find the azimuth, but the roads/tracks from the original description are long since gone. I'm not sure how the existing road aligns with the old roads.

Found this 1936 mark in good condition. I hadn't been to this park in a long time, so I went ahead and drove the loop trial before stopping for the benchmark.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in August 1993.
  • 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.
