Um... you realize there is another one up there, no?
#1 is still intact. The triangle one .. only the nub is there.

Do you really want these? I have prob. close to 50 if you include the boundary markers.
(I had this crazy idea to find all the boundary markers some day... but have yet to pursue it)

Have never found the Eagle Peak one.. looked a few times now to no avail...

well, I'm obviously not too good at finding these things. Gives me another reason to go back up to Clouds Rest. smiling smiley
Never looked for one at Eagle Peak. If a summit/peak is in the GNIS (Geographical Names Info System) database, I bet there's an official benchmark.

Edit: the original idea for this thread was to get as many as possible, from lots of different people, to see where we've all been. Then a super guru like you could fill in the missing/obscure ones.

If this is supposed to be a thread about USGS Bench Marks photos, I would suggest it would be a more attractive thread that if instead of just providing a link to your USGS bench mark photos, that you link the actual photos to your post so the bench mark photo appears in the post itself. Just a thought...

Here's YOUR photo of the Cloud Rest bench mark.

(Just go to the photo and right-click on it, you should have an option that states 'Copy Image URL' or other words to that effect. Select that option. Then here in this forum, click on the 'Insert Image Icon' and then paste the URL that you copied from your photo. Once you get the hang of it, it's isn't too difficult.)

Sorry, I had forgotten that I asked that question about bench markers before. Thanks for the tip on the triangles. Although not all of them are provided/seen on the USGS maps, ie Nevada Falls & Watkins. The "X's" mark the high points, but that's not necessarily where the markers are (i.e. Watkins again).

When the map shows "BM 8161" near Murphy Creek TH along Tioga, does it mean we should find some type of marker there?

Short answer is yes. With road and trailhead improvements... YMMV

Just clicked on the second link (NGS) that you provided, lol. First search filter: Mariposa County, then Tuolumne. The last column, "Description," could use some improvement. No listing for North or Basket, for instance. But in all its glory, I see a listing for "EAGLE." I'll punch those coordinates in and give it a go sometime. There are quite a few groups of rocks up there, so who knows which one. It doesn't have to be the highest point.

Last time I was there I hunted and hunted and hunted... and found nothing.
I even went WAY down towards Middle Bro... and just found absolutely nothing.
Prob. need to send Bearproof there to find it for us. He has a nose for those thangs.
Once the leaves a start a changing... I'll do an overnight up there ... and look around.

Here's the link to marker and info: Eagle BM. The "green" symbol on "scaredy cat" indicates "marker found"

Why isn't Taft Point marked on the "scaredycat"? HR0764 looks to be Oh My! Don't see El Capitan. But I'm seeing a pattern of sorts.

Glacier Point disk is marked by a triangle, while Basket's and North's have +/x. I bet Taft Points marker has the +/x (which it does). I'll guess YP has a triangle (and waddaya know...).

So the two links you provided above only give the locations of markers with triangles. The other ones must be in a different database, or were used for a different reason. I'm sure others have already figured this out centuries ago, lol. And when you look at the topo maps, that's exactly what occurs. So no wonder nada on Polly. If a location is marked with either symbol (x or triangle) on the map, it means a round discs *might* be there. But if a location is not marked with a symbol, that means don't bother looking there.

Thanks! At least there's definitely a good reason to go back! Along with the cascade that spills from Lower Lake.

btw, what are the odds the Eagle marker is somewhere in the meadow? Or somewhere along Eagle Creek?

The marker would most likely be in a location where it has line-of-sight visibility to other markers so that its location relative to these markers could be determined using traditional (non-GPS) survey methods. (Perhaps this is why there is no marker on HD--its relatively flat top would render the marker invisible to other lower surrounding markers...)

That makes sense. According to official records, it's supposed to be sitting on a boulder - recorded in 1955 or so. Maybe that boulder has fallen since.

Hi. So... there are sort of two on El Cap. Both are sort of on The Nose.
One is at the base... and one is at the top... the brink... along with a small lock and clip.
(some tie in spot I guess)
The one at the base is long gone... only the nub is still there.
The one at the brink ... I can't say... it was there in 2008 when I visited it.
I've been meaning to go back but ... it's a long way down from the top.

Anywho... the one at the base looks like this:


The one up top looks like this:


It's along the brink. Right here:
https://mappingsupport.com/p/gmap4.php?ll=37.730105,-119.635234&z=16&t=t4
So I guess not exactly on the nose top...

Anywho... if you go... lemme know the state of it please and thank you.
El Cap been on my radar for last couple months but too much other stuff
enticing me.

that so many enjoy and find interesting.

Thanks! Not sure if I’ll ever get to see

What's annoying is that when you search for it in the NOAA Database, it's not listed. Or it's not obviously named. Will likely make another trek out there in the week or two. Have never taken the trail from Yose Crk CG. If lucky, will come across a few climbers again.

Old maps seem to indicate once upon a time, there was some type of marker at the high point 7569. Easy to take, or maybe struck by lightning? Just like the one at Eagle. This one annoys me more than any of them. I've offered to be part of the reset team, but it's been met with silence thus far. tongue sticking out smiley

Chick-on,

I haven’t finished my El Capitan replica yet, but I did find a map which shows the location of the benchmark at the top edge (with matching elevation) and the one that was vandalized at the base. Is the 7042 BM as close to the edge as the map indicates? Do you happen to have photo that show the benchmark in relation to the edge or the general area/view from up there?

It also shows a benchmark on the summit with an elevation of 7564’.



Here is a link to the USGS report that includes this map and a couple of others as well as lots of great photos and information.

Anywho... yes, the other one up there (one still there... is close to the edge)

It's more or less safe... just don't take like 3 more steps unless ...

That's a great photo! I did look at your map link, just wasn't sure if the BM was really that close to the edge as the maps show. Looks a little terrifying given the downward slope leading down to the BM...and that long last step if you go to far...

How long/difficult is the hike up there? Where is the start of the trail, down in the valley or someplace else? The only hike I've done in the park started at Glacier Point and went over to Nevada Falls, Vernal Falls and back through the Valley to Camp Curry. Looks like I hiked past a bunch of the BM that day, but I wasn't looking for them in those days unfortunately. That was over 20 years ago!

Would it be ok if I use your photos once I get the keychain done (on the website page for the keychain)? I can credit the photos to you if you want.

Thanks again for posting them.

There's a number of ways there...
(not to mention straight up!)

Old Big Oak Flat TH (off of Big Oak Flat Road) - 10 miles to top of El Cap
Tamarack Flat CG - 8 miles to top of El Cap
Yosemite Falls TH - 8 miles to top of El Cap
you can come up with others... but those are pretty much the closest w/r to trails
that are maintained and such

I'll let you do the math w/r to elevation ... (ok, it's another 500 ft down to the edge BM)

Anyzoo...

Here's two from the marker... east and west





If you want to repost those or the other one... go for it.

I looked into that 3D modeling thing a bit... but didn't get very far.
Watched some of the vids... then tried playing with gimp but the plugins weren't there
and yadda yadda yadda... something like I had to do some "work work" or
something and then it was "Friday" ... hehehe

The "HETCH" one is no longer "viewable" without a shovel and maybe a metal detector.
The road was redone years ago and was raised. There is a photo of where it is suppose to be.
Found one at the first switchback up to Beehive at Hetch Hetchy (BM 4050 on USGS)

Also added Whitney ones. Pretty interesting that there is a "Division of Highways" one up there.
How apropos...

At one time, there was thought of building a road to the summit of Mt. Whitney, a là Pike's Peak. Fortunately, it didn't come to fruition.

Studying the old topo maps of Yosemite now online from the USGS, I'm wondering if you have come across any boundary benchmarks of the original 1890 boundaries of Yosemite National Park. I don't know if they took the time to place any before the boundaries were changed in the early 1900's.

In 1906, the boundary of Yosemite National Park were changed. Were the 1906 boundary markers you found from the original Yosemite National Park boundaries, or from the new boundaries that took effect that year?

The markers mark the boundary of the current Park. Certain of that.
However, point me to the exact maps you are looking at so I can see those maps.

The map from Princeton shows the boundaries from many years.

Here's a image of the May 1900 topo map of the Yosemite 30' Quadrangle I was referencing. This maps shows a good portion of the original western and southern boundary of Yosemite National Park.




Here's a link where you can zoom into the image of the topo map: May 1900 topo map of the 30' Yosemite Quadrangle

Ok. Yeah. Got it. As soon as saw link yesterday was super excited that I'd be
able to snaggle the Princeton maps in their entirety. Unfortunately not so.
The map you show has pretty much been in the Chick-on set since putting it up.
The answer is the same... the boundary markers are along the current border.

Thanks for sharing this. Fun hobby for sure. Now there needs to be BM reset teams. So many have been destroyed, lost (e.g. base of El Cap) or stolen (e.g. Eagle/Clouds).

And to elaborate on chick-on's posting, the NOAA datasheets provide information both on the benchmark itself as well as the reference points. For example, the picture at the start of the thread is technically not the benchmark itself...it is a reference point to the benchmark. According to the datasheets:

HR2868| PID Reference Object Distance Geod. Az |
HR2868| dddmmss.s |
HR2868| CS5568 CLOUDS REST RM 2 5.850 METERS 03628 |
HR2868| CS5567 CLOUDS REST RM 1 5.620 METERS 27436

From reference mark #2 pictured the benchmark itself should be almost due north 5.85 meters (in the direction of the arrow). So when benchmark hunting, be sure to get the actaul benchmark!

May give you yet another reason to go up Clouds Rest!

And these markers were used to mapped the country. Since everything has been mapped, there's no need for them to replace missing markers or add new ones (i.e. on Half Dome).

By the last NGS "data sheet" report (2006) both of the "reference monuments" (RM1 & RM2) were still intact as was the "triangulation station" (not a "benchmark"winking smiley but they mentioned the main station appeared to be aluminum (rather than brass or copper) and that the stamping was obliterated. It was originally monumented in 1905.

Hmm, the travails of date sequencing instead of conversation threading. Thanks Chick-On. I should have realized you would have known and answered the question. Somehow I missed it.

Is there a story on why there isn't one on Half Dome? Did someone steal it? I could see that it could be stolen multiple times as a souvenir so maybe Yosemite decided to just not place one. What is funny about that though, is if you were showing it off to anyone that cares (a legitimate hiker or backpacker) they would be the one mostly likely to report you---I know I would.

I don't know. Every REI I go to has one so I figured Half Dome deserves one also.

Have you ever seen any photos of the rime ice that builds up there? Between that and 100mph winds, I wouldn't begin to go up there without proper clothing and gear. There's some kind of club for those who have done it and survived it, but I can't remember the name of it.

Re: Official USGS Benchmark Thread
May 04, 2015 12:54PM
Half Dome doesn't have one because it was too hard to get on the top of in 1905 (when the one on Clouds Rest was monumented). Back in the day these "triangulation stations" were sighted from numerous other stations and had many horizontal angles turned between them to establish their horizontal location. A lot of prominent peaks have them but they needed to be accessible and needed to have views of other peaks to continue the chain of these surveys.
Re: Official USGS Benchmark Thread
September 07, 2011 09:13AM
I've always been interested in finding the oldest benchmarks I can. On the way up to the Mariposa Grove, the current road passes close to the original 1864 Yosemite Grant boundary, and there's a benchmark off the side of the road that is dated 1902. Has anyone ever seen one with an older date than that?

Also, if you look at a 7.5 map you'll see the orignal boundaries of the Yosemite Grant for both the Valley and the Big Trees. I noticed that todays Wawona Road passes right near one of the corners, and so I located the corner benchmark mounted on a 6-inch pipe that sticks a few feet out of the ground in a road cut. The interested thing is that you have an 1864 "corner" in a 1930's roadcut, but the benchmark had a date from the '50's (or close to that.) I would like to find the other 3 corners of the Big Trees grant. Supposedly, the Yosemite Grant corners that weren't peaks were marked with rock cairns.

Another fun one is up at the Great Sierra Mine near Gaylor Lakes. There's a cool old Iron Cross looking marker, with an "M M" stamped on it. I believe this stood for Minerals Management, and it was used to survey to your mining claim.
avatar Re: Official USGS Benchmark Thread
September 07, 2011 10:17AM
The oldest one's that I have seen are the US Forest/YNP boundary markers. 1905-1906
Most of the triangulation ones I have pix of are 1952, 1956, or 1957
El Cap is 1905. A few don't have dates or are so damaged...
Conness is 1934

I was unable to find anything really on Illiouette Ridge or Boundary Hill w/r to the Yosemite Grant.
Been meaning to finally get to Indian Rock (not the Arch) to check that spot out.

Thanks for the info. I'll have to look at pix I took the one time was up at the Great Sierra Mine.

Watkins marker: 8235'? I have been looking at the wrong place for sure. Many of these things are put in places that are either unexpected (Watkins high point is 8500') or at a spot I prefer not to go (Yosemite Point rail corner).
Re: Official USGS Benchmark Thread
September 07, 2011 10:28AM
Actually, now that I think about it, the one on the Mariposa Grove road was probably 1905, not 1902. It was a USFS/YNP boundary. (of course, no NPS in 1905, but 1906 is the year that the Yosemite Grant was added to the park)

I would have expected Mt. Chick-On to be much taller than 5150 feet, esp. since it is almost definitely in Yosemite where 5150 barely gets you above the Valley floor... Or, maybe it's not really the elevation... but I've always been under the impression that Chick-On was a voluntarily participant, although he is usually rolled up in a plastic bag, stuffed in the sleeve of a jacket, and crammed into a backpack...

Chick-on and I located the BM at former site of Gentry's Ranger Station:



The NGS data seems to be mostly correct:

HR0762'DESCRIBED BY COAST AND GEODETIC SURVEY 1958
HR0762'4.2 MI W FROM EL CAPITAN RANGER STATION.
HR0762'4.2 MILES WEST ALONG BIG OAK FLAT ROAD FROM EL CAPITAN RANGER

HR0762'END OF THE TWO-LANE ROAD. A STANDARD DISK, STAMPED D 270 1935
HR0762'AND SET IN THE TOP OF A CONCRETE POST. NOTE-- 38 FEET EAST
HR0762'OF A 60-INCH PINE AT EAST EDGE OF THE ROAD, AND 24 FEET NORTH
HR0762'OF A 48-INCH CEDAR IN A CLEARING.

The telephone booth no longer exists, but you can tell where the OBOFR narrows and where the old ranger station was (flat area east of road), just north of a gully, and both the "60-inch pine" and "48-inch cedar" are both there (I have to assume these dimensions are circumferences, not diameters...)

Going over older photos, I believe that the "48-inch cedar" is at the left of this picture, which is looking roughly south. The road is to the right. Gentry's Ranger Station was in the flat area in the foreground. The BM is probably behind me to the left:

The fire ring was not present, neither of us recalls seeing the taller witness post, and I don't understand the reference to "other road" (perhaps the confusion is that the OBOFR was two-way above Gentry's, but one way below it...). With the original NGS description in hand, the two trees were somewhat obvious--but this was my fourth trip here :-)

Ah, but the ranger stations were probably at those two spots because the old road was one way for some years between those points (on a schedule). A ranger had to be on hand at each end to reverse the flow, so to speak. The Gentry's ranger station would have had more elbow room if it had been built up where the El Cap trail comes in (at the site of Gentry's hotel and sawmill), but that would have been just outside the boundary of the original grant. So they put the park entry station at the first point on the road where they could place it inside the park. The El Cap station, of course, had no reason at all for existence except when traffic on the road required it, so it must have been established later than the Gentry's one. The Gentry's station would have been much older, and would have disappeared when the park boundary moved, except for the traffic thing....

As soon as the road was shut down for good, neither ranger station had any reason for existence.

Here are a few non-USGS Yosemite-area benchmarks that hopefully aren't already on this list:

Mt. Lyell headwaters basin, approx.1/4 mile south of Dome 11061:


East of the outlet of Maclure Lake (the orange circle/arrow is a big giveaway):






There was also a faint orange circle around the STA 1 marker.

Does anyone know if there are any other benchmarks in this 1949 STA # series?

I thought it quite strange to see this orange stuff at Maclure. Such a lovely lake.
(was wondering where #1 was... good job)
"They" had all kinds of bug catching devices and Glacier analyzing equip around
that area when came over Hell Hole and up Lyell in 2010 (where does the time go) sheesh.
Very cool thanks

I stumbled upon a benchmark on our way back from our failed Basket Dome attempt. It's located on a rock where the four trails intersect; to Tioga Rd, to North Dome, to Snow Creek, to Yosemite Falls. I should have taken a picture but I was too tired to think about by that time. The maker is so corroded and pitted that it is mostly unreadable. I think the date was 1905 but I'm not 100% sure. Anyone seen this one before?

You'd be surprised at how many "benchmarks" are set in vertical features (bridge abutments, rock ledges, etc.). Quite of few of the monuments that are pictured in this thread aren't really "benchmarks" but are "triangulation" stations (horizontal coordinates only, not vertical).
