Poor. As noted by BPA in 1984 the benchmark is not here to find. Did locate the Reference 2 marker. Others noted "finds" on the BM. Two were pictures of the summit, one was a picture of Reference 2 marker. No pictures of actual BM; no true finds.

First time up here, will be back because it was just that spectacular! Found this one with Swiss Cheese Brain. His picture tells the tale. Thanks!

Fantastic day for a hike. Not much left of the tower.

Looks like we get the coveted third to find on this one. I'm always amazed that someone would have hiked up here early in the 20th century to put a brass disk in a mountain top. Very cool spot, we loved our hike up here today. Marker is in fantastic condition.

Found it on my hike up from Noisy Creek. If you are walkin up the trail the benchmark is before the ruins of the look out.

I believe, at least as far as geocaching is concerned, that we might have FTF'd this benchmark. We've been up here a dozen times and always enjoyed the spectacular views. On this particular occasion, we were planting a geocache. We love this place and this trail and the entire trail system of the area. You just can't beat it. I hope that people who find our new geocache will find this benchmark too.

Thanks,

We have been to this summit a dozen times, but this time was special. We planted a geocache up here. The views are spectacular. The kids along with us are our Jeff, Christina, Jaz, and Caroline.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in December 1991.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.) The vertical order pertains to the superseded datum.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
