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.

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 one.

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 one looks good and is easy to find.

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 good shape.

Found

This one is clearly marked 'F174' and is as described. It is located in the upstream sidewalk about 75 yards from the Nevada end of the dam, directly across from the Nevada side (men's) restroom.

Its funny to see all the visitors just walking past these benchmarks, but when I stop, bend down and take a close up picture then walk away. other people then scoot over and take a picture too..

Found while visiting Hoover Dam while on vacation in Vegas for a Sweet Adeline Competition. Wasn't even looking for it. Looked down and there is was.

(Translated with Google):
Some geocachers were planning a trip to the US for ET Power Trail and various old geocaches. I was asked if I would like to join the tour and I had! On 10/01/2015 our (Butjer, Tudor99 and ropno) personal Roadtrip 2015 began.

We started in Las Vegas with 93°F hot humid summer weather, explored the "Strip" and drove to the Hoover Dam. Here we found a lot of bench marks.

After a few days we went into the desert for Extraterrestrial Highway with its many, many (2400!) ET caches and brought the rain. The temperature dropped through the storm clouds on homelike 65°F, we had no dust on the "dirt roads", no flooded roads as it "poured out all buckets" rarely about us, the clouds mostly very fixed in the near mountains. We didn´t get a sunburn and needed less water than planned to drink. We saw a lot of cattle, horses, antelopes, a coyote, rabbits, many birds, bugs and insects, as well as beautiful areas and landscapes, yellow flowering shrubs and more cars and quads than expected, but fortunately no rattlesnake or scorpions. On the fourth day in Nevada desert the sun came through and we saw still the expected "desert feel".

The second week our tour continued north to the oldest caches over Lake Tahoe, Eureka, Crescent City to the Pacific coast (50°F, fog) and on about Oregon City to Seattle (63°F, sun) to Groundspeak HQ and there was even time for trip to Utah, Idaho, Montana and a day trip by catamaran to British Columbia in Canada.

After 11441 mi by airplane, 3538 mi by car, 175 mi by ship and approximately 72 mi on foot walk unfortunately and we had to go home on 10/16/2015. But the idea for the next US tour is already on the horizon...

Best regards from Germany

Fun day out with the mother on our girls trip from Oregon to Vegas. Still in good shape!

Was walking on the dam with the family and saw a few of these out in the concrete. Took a few notes so that I could log these later. Was really glad to be able to take the family out here, and wish that I had known just how many were on site. I might have been a bit more agressive in locating these, since the number of geocaches here are somewhat minimal.

Found many benchmarks while visiting Hoover Dam, though most of them did not have a designation, or the designation was not clearly legible. Also had to chuckle at the description of the benchmark being placed on a 'light structure' of 'questionable stability'...although I don't recall the exact location of this benchmark...maybe it wasn't on the dam itself.

Found this while vacationing with Lady Elwood. The Benchmark is in great condition.

Went out to Las Vegas on vacation and took a trip to the hoover dam. This thing was loaded with benchmarks. I guess that is normal for one of the 7 wonders of the United States!

The UGE (CoheedDrummer, H-Rob(RTR), and J-Brown!) and a couple of our wives (MrsFirenze and MrsCoheedDrummer) came out from Montgomery, AL to Las Vegas for a geocaching/sightseeing trip this week. We grabbed some caches that were high favorites, some for the Jasmer challenge, had a day for the numbers along Route 66, and even grabbed them when they just happened to be near us. Had a great time doing ALMOST all the things Vegas has to offer. Spent an afternoon at the Hoover Dam, drove through Zion National Park, and spent a sunset at the Grand Canyon. Finished the Extremely Busy Day Challenge as well. We also ate some good food at Craftsteak, Mesa Grill, and the Cheesecake Factory. What an awesome place to visit!

Saw at Hoover Dam!

Another Dam find. The Platoon and I located this and took some pictures for later use. Finally we logged the find.

We weren't really planning on looking for benchmarks during our visit to Hoover Dam, but they were everywhere we looked. Managed to match 9 photos to the descriptions once we returned home!!

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.

Another find with my mom while walking the dam.

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.

Another easy one on 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!

Enjoyed my day at the Dam.

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.
