I was atop Shedroof Mountain and spotted this Triangulation Station BM stamped Y1930.
The elevation on the disk is correct for Shedroof Mtn.

My searches led me to this one as it mentions the stamp of Y1930 in the description.
I cannot find a BM listed for Shedroof. Nor can I find a listing for the now demolished Shedroof Lookout. I even checked the .dat file of the archives.

Can anyone help me figure out why I cannot find a listing for Shedroof and/or why the stamping matches the description of North Baldy?
Thanks!

This benchmark was recovered in poor condition today. The disk has been broken off, but the pin remains in the rock and the mark where the disk used to be is clearly visible.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1991.
  • 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.
