Benchmark is in good shape. Found while hiking the butte and managed to nab 3 caches as well.

Recorded while on hike to Kelly Butte.

Found this benchmark after finding the nearby geocache. All is good. A beautiful day, and a very popular hike!

Very nice climb to the top! Good to see the tower painted and returning to it's former glory. Found with the Parkerz.

Found easily today, looks like the volunteers have been working hard on getting Kelly Butte back to it's original glory!

Found this one accidentally while looking for the geocache close by. I didn't even know it was here, but I happened to look down and see it. I recorded its coordinates and then logged this as a find. Found with my friend and dad.

Not easy to get to, but worth the effort! We were racing sunset to get here, find the cache, visit the lookout, and get back down that gnarly slope before darkness or bears got us.

Found this while hunting the nearby geocache.

Not an easy lookout to get to!

Found this back when I was up there geocaching

Logging this one with today's date, instead of when we initially found it. This is still in good condition and is slowly being restored over a couple of years. Contact me for more information on this benchmark and the nearby geocaches.

If you are looking for a nice hike, I did this with my 4 and 8 year old without too much problem.

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  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)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 Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
