this thing looked pretty beat, like a boulder plummeted it.

Found the station easily; coordinates were good and the directions were perfect. In order to find reference marker 1, I walked about 23 feet east from the station and looked around, expecting to find the disk. I didn't see it, and it took me a minute to realize I was standing on it! It's actually the second time that's happened to me. I was unable to find the second reference mark. I think I may have found the rock that the azimuth marker is located on, but it was covered with several inches of packed dirt and I wasn't able to get down to the surface of the rock. Now I'm on a mission! I want to find the other two disks.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1999.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
