Finally figured out how to log these. Just happen to see this one and got coords and a picture to have the data to log it. Valentine's Day caching with firejoewife, awesome. We are making a round trip from Vancouver to bridge of the gods and back to troutdale.

photoNear the benchmark.

Me Too.

Can't miss this one.

A few people have found this one. My turn after celebrating my wife's completion of the Oregon PCT. The scary thing is that the bridge is 72 years old.

Looks the same as 10 years ago.

Was great. I got a fantastic photo by standing centered under the bridge and looking north.

its a crappy day for caching but we are determined so we stopped in town to refuel

out with our geo-buddies doing the Tomb Raider series and stopped in town for a bite to eat

I found it right when we pulled up in the geo-mobile. Papa-Penguin logged the picture.

Out with the kids today for a family bike ride. We discovered this one when parking. Papa-Penguin has the picture logged.

Discovered while getting ready for a family bike ride.


In the area getting some caches and stopped by to find the benchmark here.

Got it!

Had lunch at Char Burger & found this in the mural at Bridge of the Gods.

I did not know you could log these. Very cool. More things to find.
Thanks uncle sam.

First Bench Mark for me. Too dark to make it down the trail under the bridge without becoming part of the legend. Scary ! Had a nice chat with the County deputy as I am climbing around the bridge. Seems my license plate light is out. I also looked a little suspicious backing up when he was sneaking up on me. It also looked a bit odd when one of my caching partners jumped out of the rig and ran across the park just before he turned on the colored lights. All in the life of a geocacher after dark. (chuckle) Actually he was great and once he realized we were not terrorists he was very helpful, showing me how to get to the murals on the bridge uprights and the info booth. TFTC

9:06 pm #64. First Bench Mark.

Out from the big city (Bend) doing a little caching in the area as we drive to Portland for a little caching.

Found going home from staying with some family for the week. This is my second Benchmark found. What a beautiful place it to be at


Got these on the way back home from seeing family and looking at college's This is my second benchmark. Found with Native Blood, countrymonkey, & Reindeer Games.


My second benchmark found! We found this one after making the necessary stop for ice cream at our favorite place there. This is such a beautiful area. The mural is amazing, but am curious as to how the eagle got painted on the bottom of the bridge. It is so neat!


Found it! It's in good condition and easy to spot if you know what you're lookin' for


Our first Benchmark find!!

I had spend the day doing The Dalles cache machine with 3MudDogs and Snark-Hunter. We stopped here since I love logging benchmarks and this was a neat one. Very cool being right IN the mural.

Found this while in the area to visit the Original Geocache


Found the nearby geocache so I had to log this benchmark as well.

would have passed this one by if not for the geocache in the same area.
the bridge keeps your eyes looking much farther up
thanks for the hint

Out on another caching adventure with Gravyman and KenandI. Cool mural and bridge.

Grabbed this benchmark while checking out the mural. In the right angle it looks like K680 instead of K380.

Love how the Indian is the guide to the benchmark. My first one!

Was checking out the mural after doing a little brunch on the Sternwheeler

Found as described

took us two trips out here, but we got it

Zowaar! Benchmark found


Too many muggles for the cache, but I scored the benchmark!!

Thanks to the Bridge of the Gods cache we found this benchmark too! Love how the mural indicates where the benchmark is.

Yea! Cache, bm and french toast.

Local cache helped us find this one.

photovery cool location

This was our first benchmark find. Found it on the way to Pendleton geocaching. Cool. Thanx!

First benchmark find, found it while geocaching.

Found this one on the mural and real close to a cache.

Benchmark in good condition although it is hard to read the first number on the brass insert. Benchmark insert in concrete abutmunt and blends in well with mural that is painted on the base

photoBench mark and GPS

Already have the cache from a previous trip - just happened to park next to this one before a hike up to Benson Plateau.


Found this on the mural with geo-buds rygemini, youdad, and little_nemesis. Youdad took some pics. We enjoyed finding this today.

Found this while out with VikingChick92, Little Nemesis and rygemini. They know I like these things and pointed it out to me. Had a hard time making out the 3 and kept thinking it was K 680.

This was our first benchmark find. We found while geocaching.

Great mural, cache, & benchmark.

Nice mural and story of ancient natural bridge. Found while geocaching nearby.

Found this benchmark on the road to Geowoodstock VIII. We really enjoyed stopping for the cache here and seeing the sights!

Found while grabbing the cache near by - on way to Geowoodstock VIII.

Enjoyed the view, the bridge, and logging the BM. Thanks.

We stopped by here and signed the log on a nearby cache on our way to Geowoodstock VIII..

Much easier to find than was the cache. I think the bridge was messing with my GPSr signal.

Found it while caching today.

Our very first benchmark found and a cache nearby was our 500th cache. A great day. Will post photo when we get home

Found this one today while hunting the nearby cache.

It looked like the belly button of the mural :)

Was caching in the area stopped and found this while I was here.

Found this benchmark while at a waypoint for a multi-cache.

My mother, sister, brother and I drove east on Hwy 14, stopped briefly at Skamania Lodge, crossed the Bridge of the Gods and drove west on I-84 on a very windy, cold afternoon enjoying the scenery and finding a few geocaches and a benchmark.

Checked this one out while finding the nearby microcache.

Found this one while checking out the mural under the bridge.

on my way home to Pullman from the coast. This is my bonus got the cache nearby.

great mural

Found today with hubby while on a day trip along the river.

Found with the wife while on a day trip to the falls. Camping near by in the Carson River Valley, enjoying the area. Yep got the cache here too.


Found this on The Bridge of the Gods...and got the nearby cache! Beautiful mural on the bridge support.

We found this one back in August, but it took us this long to figure out how to log it.

Out cacheing and we get a bonus.

Looking for a micro. Scored this. Nice painting.

Wow, I just happened to stumble upon this benchmark while looking at the mural under the bridge. This is also my first benchmark find.

Up close and personal doesn't always work. When we stood back it was easy to spot. Havn't figured out the other one there, maybe on the way home.

Loved the mural (and took lots of photos, one of which I will upload tomorrow).

photoSurvey disk in the mural

Found on a nice day of biking to Eagle Creek. Can't miss.

I've seen a few benchmarks in vertical concrete piers, but never one with a mural painted around it.

My #2 son, Christopher, and I attended the 8th Annual Columbia River Gorge Geocachers Potluck in North Bonneville this afternoon. We did some benchmarking and geocaching before and after the Event. This was Christopher's 9th find of the day.

Looked for this because of a nearby geocache. Pretty easy find.

Found it while visiting the nearby cache.

Found this one easily with the information provided from nearby geocache.

I have never seen a benchmark location quite like this before. Atleast it won't get vandelized as easily.

Doing my thing finding things.

Liked the mural and the arrow pointing the way.

Found this after spending 4 days hiking on some trails in the Columbia Gorge. It was interesting to spot it right in front of me sort of out in the open.

Found with dlbisblest when we were on a Volksmarch in town.

Found while on a Volksmarch in Cascade Locks.

I attended the Country Caching: WSGA Southwest Washington Chapter Potluck Event at Rock Creek Park in Stevenson, WA. It was an absolutely beautiful day however the wind was quite strong and cold at times. Afterwards I did geocaching and benchmarking on both sides of the Columbia River.

I picked this benchmark up as part of a cache nearby.

Stopped here for the new cache and made the find.

Ornith showed me this one.

Stopped to look over the river at the overlook and to enjoy the bridge. Thought there might be a BM here so I kept my eyes open and was not disappointed.

photoBenchmark in Cascade Locks, OR

Actually took a photo of this mural w-a-a-a-y back and didn't even realize that there was a Benchmark in the photo. Recorded it this time on our way to geocache in Pendleton, Oregon. ORNITH

I've viewed this mural many times and completely overlooked the disk as I was not logging benchmarks at that time; returned with ORNITH to check out the disk today, and it is in fine shape.

I saw this benchmark in the mural on the support for the Bridge. I was on my way to hike on the PCT.

I saw it as we drove past. Came back to get a closer look after going to the East Waind Drive In for an ice cream cone.

One of our last trips through the Gorge before moving to Montana. Had a good bye lunch at the Charburger :-)

I just happened to notice this on a cool January Day. It is in the center of a mural depicting Cascade Lock's History.Great Location and beautiful Bridge.

  • 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.
