Found this one on my birthday.

We parked right next to Reference Mark 2, which was interesting since it was set into a WWI monument slab. We found the bolt by the scopes, and then walked over here for the benchmark and the the cache. I think this might be the oldest one I have seen. Thanks!

Geocaching.com doesn't have a page to recognize Reference Marker #2 (SV1172) listed on the original datasheet for SV1171 as:

"REFERENCE MARK NO.2 IS A STANDARD DISK SET IN THE TOP OF A CONCRETE
'BLOCK 4 FEET SQUARE--A MEMORIAL TO WORLD WAR VETERANS."

SV1172 MOUNT SPOKANE VETS FLAGSTAFF 41.428 METERS 19634 |
MOUNT SPOKANE RM 2 41.126 METERS 19832 |
CHISELED COPPER PLUG

I didn't realize there was two others nearby, SV1619

I'll print the data sheet next time and see if I can find them all.

Have found several benchmarks (purely by accident) on our travels, but this is first time I've been able to figure out how to log. Found the first near the TB cache on 8/30/10, and the #2 marker on 10/15/11; the last day the upper road was open for car traffic. We're skiers, so the next we see this area, it will be under much snow! Enjoyed our time walking around the vista house, chair #1 & 2 and looking at the ski runs we usually ski on.

Out geocaching and there it was. Nice little bonus to the day!

Found it and the RM #2. Also found the scarred up one over by the Vista House, and some sort of marker at the peak of Mt Kit Carson.

Found my first benchmark while hunting cache "On Top of Mt Spokane TB Resort" on the very top of the mountain. It was embedded in a cement block that looks like it used to be an old flag pole mount.

This is the reference marker on the World War I monument pointing right to SV1171. It is label as 'No. 2'.

We stumbled across reference point #2 on accident while visiting the summit to enjoy the views, look at the vista house and have a picnic... The next time we come we'll look for caches and the other bench marks!

Apparently we only found Reference Marker 2 - it's our first benchmark find, so we didn't know to look for the triangulation disk ^_^ - next time we'll know better

Picked up this bonus doing the TB Hotel cache, but I guess we missed the other two up here! Oh well, the views were awesome!

Stumbled upon this while finding nearby cache this afternoon/evening, hard to miss this one.

photoYup, it's a BM.

Beautiful views from up here. Wish I brought the paper for the cache here as well. Also found 2 other nearby markers.

It was hard to miss this benchmark. It is in really good shape.

Easily located this benchmark and the nearby #2 reference marker.

Found this BM and a nearby RM today.

No trouble finding this one. We stumbled across it while looking for a nearby geocache. It's in great shape.

Found it along with the nearby cache with our Japanese exchange student.

Always great to find a Benchmark. I love seeing the date it was imbedded. Great Views here!

Took a motorcycle ride to the top of the mount. Wasn't after any geo stuff but recognized the marker from the web site and decided to investigate it here. This is my first benchmark. Will surely be looking for more.

Found this when doing nearby cache. It is in good condition probably because it spends so much time under the snow.

I found the BM labeled 5881. It is scrapped up and hard to read.

Found in good condition also found the reference mark.

Yes, the disk is still there. As noted in previous logs, the disk seems to have taken quite a pounding and is damaged. Part of the information on the disk is not readable. I had a dickens of a time finding this one to log. My coordinates put it at N47 55.426 and W117 07.867. X-C Shadow

Found while searching for the nearby 'Vista House Renewed' geocache.

Found with bocaboda kinda by accident. We were not looking for benchmarks and the park is really closed. We were there on official business with a contractor remodeling the Vista house when we spotted the benchmark and started to investigate further. This is a great location and view. My guess is that you can find this place if you want to bike or hike up or perhaps when skiing, althought that might be a bit harder. There were several benchmarks, most of which are noted in the notes for this benchmark. We will do some more investigating as these seem to be as much fun to find as caches.

We were up looking at the Vista House for a glazing job. Beautiful day, a bit chilly a this elevation. Stumbled on these, not really looking for benchmarks today, but saw these and got really curious. We intend to find out more about these. Found with bo of bocaboda and luv2fish.

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.
