Came by while walking the never tail loop with emiliexo. Area where benchmark is has changed. Porta potties no longer stand at GZ. Permanent outhouses were constructed at GZ with the benchmark between the 2 far left ones. Satelite images reflect this and pictures to be included to show this change. Glad to see this one still going! :)

Was on a cache hunt and found this kind of by accident. Will up load a picture.

(8) found on a this cold day, I rather be near the porter johns on a day like today than a hot day with many
mugglers around. bench mark is right near them.

Agreed about the poor location. At least the portable toilets aren't on top of the mark.

  • 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.
