Found this benchmark today in good condition. Reference marks 2 and 3 I would call in fair condition, as they were considerably scratched up, however still legible.

Found the reference mark. Didn't know the bench mark was buried. We wouldn't have wanted to tear up the terrain anyway. Sustained wind gusts of 25+ mph made for an interesting visit to the top.

Found it today while in the area. Glad that other previous finders mentioned the need for digging so had a tool with me not needed for caches .

Recovered as described. The station mark, RM2, and RM3 all in good condition.
My 2000th successful benchmark recovery logged on Geocaching.com!
Out of twenty logged recoveries, only four (including mine) appear to have actually seen the correct disk.

Found Salt 2 & Salt 3 reference marks but didn't find the Salt marker. Didn't have the data sheet with me so didn't realize you had to dig for it. We could tell by the arrows on the reference marks about were it should have been, but with no shovel couldn't make the find.

Great hike this morning picking up caches in South Mountain.

I finally made the journey up here to see this station and to pick up the nearby geocache. It was quite a hike up and back down. I ran out of water 100 feet from my car, so I was lucky.

Recoverd today with southpawaz, after a bit of tape measure stretching and a little digging. Alo located both reference marks.

Returned today with MTime to locate and log this station. We measured the distances from the reference marks, and started digging at the indicated point. We found the station in good condition within 4 inches of where we measured and started digging.

Original Log, DNF 5/6/08
Located Salt RM2 and Salt RM3 this morning, but did not locate the station itself. Did not have the data sheet with me, will note here for emphasis that the data sheet indicates the station is 7 inches below the surface of the ground.

Found It, one heck of a climb, very steep rugged and rocky. Some great caches along the way, 7 - 9 mile round trip hike, San Juan Rd closed permenantly, but the ranger indicated you can access this peak via 43rd or 51st ave off of Elliott. But not sure, haven't tried this route yet.

Found this one very near a cache. If you're going this far, might as well search for it.

Boy, what a hike and views. It was perfect weather for the long hike. 1200 feet above the valley.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in August 1993.
  • 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.
