There were two brass disks here at the Mount Washburn summit. I somehow do not have a photo of the second one. It was really windy, and I was tired and hungry. The one I have a picture of says it is a triangulation disk. The data sheet says it is in a monument, but both of the disks I saw were in concrete embedded in the pavement.

Found on my hike to the summit today. All is well. Beautiful views up here.

We found this benchmark after making the long hike to the top of Mt. Washburn. Very windy up top today.

Found it visiting the virtual cache Go Ahead.

Found it at the top of Mt Washburn!

Great view from up here! disk in great shape!

Walked right over it, thanks!

Found both benchmarks while we were here!

Found while at the summit for the Washburn Challenge, after running the Inaugural Yellowstone Half Marathon. Location is in good shape, but was it windy today.

Recovered station mark and both reference marks. Weather drove us off the summit before we could move to the azimuth mark.

Noticed when taking picture for a virtual there. Still in good conditions!

Noticed this Benchmark after I found the virtual cache. It's always fun to make multiple finds, especially after hiking 2000 feet.

For this year's summer vacation Team Geo-Moppel (together with little Cachingbär) and Team viennacache have been visiting the United States, travelling from Denver, CO to Seattle, WA. On the way we were able to find this benchmark. Best greetings from Vienna, Austria! TFTC, Team Geo-Moppel with Cachingbär

Got the benchmark along with the virtual cache here.

Put my backpack down right on top of it before even beginning the search.

Discovered while vacationing with the family.

Found this benchmark after a nice hike up in the morning. Walked through a small herd of bighorn sheep and watch some young rams butting heads for a while. Found triangulation mark 1 as well, and of course the lookout tower.

Found while staying on Mount Washburn.

Found this while hiking up the mountain!

Nice hike to the top. Weather hadn't broken yet. Great views. Next day I hiked into the interior of the Pelican Valley and got close to a lone Wolf!! TFTB

Found while on a western vacation in 2011. We were just reviewing our vacation photo album and realized that we had forgotten to log our find. Wow what a view, wildlife, wildflowers and a great hike.

Came out to Yellowstone with Boy Scout troop 59 from Clifton Springs, NY. Had a beautiful day to hike. Also had a wary coyote pass right by us on the trail. Thought he was begging but the ranger at the top said he was actually hunting the little animals along the trail that beg for food. Saw him several times going up and down.

Found in good condition at N44 47.861 W110 26.033. Ref disk 1 in good condition at N44 47.860 W 110 26.027. Ref disk 2 in good condition at N44 47.848 W110 26.031. Rocky knoll east of station is marked stay on trail. Being that I saw a ranger in the station building I did not try to search for the Azimuth disk.

One of 3 discs I found at the top of Mt Washburn. All are in good condition

Found it while speaking with someone from Poland.

Took a ranger led hike at Yellowstone to the top of Mount Washburn. The ranger hike was offered every Wednesday through the summer and led by a firefighter that was in the 1988 fire. It was a great hike and very informative. By the way - This was my first Benchmark. Attached is a photo of the No. 1 triangulation mark.

Found this with my parents. They hiked me into the ground. Saw the reference points also.

Found this benchmark with my wife and oldest son - Darth Brock. It was a great hike from Dunraven pass. The gps said we did the 3.5 miles in 70 min. Still snow on the trail side in a few places. We also found the reference points.

I saw this marker in the ground beside the Mount Washburn summit and I knew that benchmarks were associated with geocaching somehow. I took a photo knowing I could use the info. later. My first.

Took coordinates on this brass cap when I spotted it on Mt. Washburn. I use monuments like this every day during my summer job, but this is the first one I have logged!

Found this one almost on accident. Quite a hike up to the tower.

Eyeballed this one after the stroll to "Go Ahead"

Wasn't even looking for markers on this family hike. One of my kids saw it and pointed it out to me (A future geocacher).

Found as described. Reference Mark No.1 Also found. Reference Mark No. 2 not found.

Got caught in a thunder snow storm on the way up. But it blew through and got a fantastic view. Definitely one of the most spectacular views, and one of the easiest >10,000 ft. views in the park.

Found the mark and both reference plates while doing the "Go Ahead" Cache.

It's about a 3 mi steady uphill hike. After about the first 1.5 mi, the kids lost all motivation to make it to the top. After promising them that they could have dessert for dinner, they suddenly became fully recharged! They made it to the top without breaking their strides. What a spectacular view!!!

I took a photo of the #1 marker on a family trip in August 2003. Now at the time I had an idea what the disk represented but it wasn't until Feb 2004 when I got into geocaching that I learned about benchmark hunting. If you ever get a change to go to Yellowstone, definately plan a half day to go to the top of Mt. Washburn- you won't be dissapointed!

You can see some of the hazy smoke from the forest fires in the background.

Washburn was my first summit ever, reached during my first drive across the US the summer of 2002. I photographed the benchmark not really knowing anything about them. It just looked kind of neat.

The actual date is July 1998. Not available on drop down list of date logged.

Control Text

  • The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in May 1992.
  • The orthometric height was determined by GPS observations and a high-resolution geoid model.
  • The X, Y, and Z were computed from the position and the ellipsoidal ht.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
  • The geoid height was determined by GEOID99.
