While walking over hoover dam i found many of the benchmarks while not even searching for them.
Now i try to ide tify them by designation and photos to log them in the system as well.
This Benchmark was definetly one of them i found.

Greetings from germany
Tim

While doing our roadtrip, I didn't think of the benchmarks. I found at least a cache a day, but about benchmarking I was just remembered as soon as I walked this dam. They are everywhere. So when I saw them I took z photo, and now I try to log them.

Found with medic

Since I was traveling from California to Utah alone today, I decided to add a number of hours to the trip and visit the dam. I enjoyed it and I was able to find a few geocaches and benchmarks along the way.

I found this one while walking the dam and could have sworn I had a photo of this. But when I got home, I couldn't find my photo. I know for certain that I found this since I purposefully found the three in the middle of the dam.

Edit: I found a photo that accidentally shows the BM! It is hard to make out, though.

Thank you! Visiting from Minnesota

Spotted this one and others while visiting the Hoover Dam with family.

Touring the bridge and dam today and then using www.findbenchmarks.com to find a ton of marks on the dam. I wish I could have had a few more and I would have pulled off a really easy 25 BM day! Oh well.

This mark is pretty clearly stamped still and easy to spot on the upstream sidewalk.

photoH174 Benchmark - Hoover Dam

I was in Vegas for a long weekend and spent the morning at Hoover Dam, grabbing the new virtual and searching for benchmarks, before heading to the airport for my redeye home. I was here five years ago and noticed they are all over the place, so why not log them. Spotted this one in relatively good shape.

This one is clearly marked 'H174.' It matches the description well, located about 30 feet NW of the center line and featuring at top 1/4 inch of the disc that is truncated. It is in the upstream sidewalk next to the first rail wall mounted light NW of the center line across from the first brass door NW of the center line of the dam.

Joyful Noise and I were on Vacation from Michigan (Brrr. and double Brrr). We took a break from finding geocaches to find some benchmarks instead.

We came for the Dam Tour, but found a bunch of Benchmarks too. Easy to find, hard to figure out which is which.

Finally got to walk the Rail road tunnel trail with sassy13, rrgeo & 50+. We ended up doing 10 miles. Glad we started early for it got really hot. Didn't expect to find any GeoCaches. And these were an added bonus.

Saw these as we walked across the dam. Thanx!

Out with fiddlefiend for some finds.

Inadvertently stumbled on 18 benchmarks while visiting from Illinois with Mandolinman. That'll teach us to wander off without our GPS.

Found this one while visiting kids in Las Vegas.

Happy Hikers

Found it. Great caching possibilities here, but not too smart for security reasons.

Was in Vegas with my boyfriend Doltishguy and found this one. Just now getting my own account set up to log it. See Doltishguy's entry.

My girlfriend and I were walking across the Hoover Dam and saw it. Didn't have my GPS because I wasn't in the benchmarking frame of mind......

Found this one along with 12 others while touring the dam. I wan't even planning on doing any geocaching or benchmark hunting while on this vacation, but I couldn't pass up the opportunity. As I expected, they are well documented and photographed, so I won't add yet another picture to the database.

Found while walking dam with mom

Didn't realize there were benchmarks here until I was walking along the top of the dam. Found this one along with a couple of others.

Found while touring the dam.

In from Pittsburgh, PA for a work conference. Decided to see the dam and I look down and realize there's a bunch of these here!

Got this on the trip to the dam.

Recovered this benchmark in April of 2001 While visiting Hoover Dam following the National Association of Broadcasters convention in Las Vegas. I highly recommend the hard hat tour.

During our wedding stay in Las Vegas (July 1992) having visited the Hoover Dam and seeing the interior and surdings. A great stay and experience.

This benchmark is on the crest of the Hoover Dam, right by the sidewalk.

Control Text

  • The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (G = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
