Found at after finding a geocache up here.

Found with TsunamiGirl on our hike to the top on a hot and then Lightning storm racked day. Living at Sea Level didn't help my O2 acclimation here. But we made it and didn't get hit by 40 million volts

got it

Found this one mounted on a boulder on top of Black Butte.

Did not have the coordinates for the benchmark, but found it on a boulder on the summit, near the remains of the old tower.

Reference Mark 2 was found at the above coordinates about 25 feet northeast of the original benchmark which has been destroyed. Reference Mark 1 was not found. The area is littered with debris from the old tower.

Found this one while hiking with friends. However, my picture doesn't seem to match other picture listed for this benchmark, even though discription does match. Two number 2 markers on Black Butte?

Found this while exploreing the top of black butte. Awesome spot

This is a great benchmark. From here, the views are incredible.

At the time of my visit, 4 generations of lookout structures graced the summit. The winter following my visit the 1934 lookout tower fell down in an ice storm. This is still well worth the effort to get to, one of the best views in the Pacific Northwest!

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in October 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  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)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.
