Disk Logo List

[Bill93]

Correction: the data sheet says AH7373 (IA) Equinox, Inc. is in Idaho (ID) not Iowa (IA).

[+BuckBrooke]

True. Also, I was dyslexic with the Air Force marker; it should be AE4289, not AE2489. I have a short list of corrections for the web page, a few in data and most in formatting. Between all of the submissions I estimate the list is going to be about 550 agencies/types of disks (probably 440 different agencies) by the time I'm through the spreadsheets. There will be 150 or so that don't have photos yet, some of which have been logged on Geocaching.

 

Here's some:

We couldn't find a PID# for this one, but had to at least post a picture so you could see the "Name" of the setting agency.

Ok, I'm done going through the state by state spreadsheets. I may (probably) have missed a few, but...

 

I have better photos for about 15 agencies, and corrections to another 15 or so. I've found a number of agencies that didn't previously have photos, but the list of non-photoed disks has expanded significantly. I'll be reorganizing things soon.

Hi

 

Can anyone tell me what type of marker this is?

Not desirable I would think, since it has no real information on it...

 

[chex_28]

bump

 

?

[+BuckBrooke]

Since one of the professionals in the crowd hasn't answered this one, I'll take a crack at it. It looks like a temporary marker put down by the USGS for a local surveying project. There's probably a USGS marker in the nearby area, or something that they were measuring. You're right, it doesn't have much significance to someone not associated with the USGS, or even from the team that put it down, and you won't be able to report it anywhere.

Here's one (DX5124) I found several years ago that is different than the US Corps of Engineers (US Army) ones that are on on Buckner's master Master Agency List.

 

Anyone know what a "Harriman Index No" is? There is a box on the disc for one, but no number filled in. Disc is from 1939. Index system unique to the Corps of Engineers? Used prior to establishment of the PID system?

 

By the way, a very nice 5+ mile hike, to a great, fully preserved (or ready for use?) Fire Lookout Station. These are now rare in this area (Southern California).

C&GS and

NGS

 

So far, I have been unable to find an example of a C&GS circular gravity station (labelled 9 in the first picture). There are examples of the rest of the C&GS stations.

 

Of the NGS disks, I have been unable to find an example of the right column middle (reference mark w/ odd arrow) and bottom (calibration station w/out cross in middle) disks.

Shorelander,

Your disk (and any others that you have) is/are welcome, as a number of the disks in the list are not NGS PID stations, but their photo was logged with a nearby disk, or mistakenly instead of a nearby disk. Your disk is the first Waymarking US agency disk I've found. By contrast, most of the Canadian agency photos are from Waymarking.

 

As a note, it's hard to make out the designation on the disk; do you have a shot that's zoomed in a bit?

 

Here are a few more agencies, from emails and the gallery:

EZ1375 (US) US Coast and Geodetic Survey - Triangulation station large (very cool disk)

[mloser]

KW1084 should probably be listed as a Penna Turnpike Commission disk and not a PADH disk, from the agency listed on the disk. That disk is pretty rare. I am pretty sure there are none east of that one, but didn't look west yet. At least none that are in the NGS datbase. I haven't stopped on the PA Turnpike and checked any bridge abutments to see if they have disks.

 

Here is another variations on the PA Dept of Highways (PADH) disks I remember seeing:

 

KW0535 has PSDH on it and the description says Pennsylvania State Department of Highways.

[+Shorelander]

As a note, it's hard to make out the designation on the disk; do you have a shot that's zoomed in a bit?

You're in luck - I didn't have one, but I went back to the area to see if I could finally find some caches over there, and I picked up a much better photo.

I found a new disk the other day, in Berwyn, west of Philadelphia. The setting agency is the Philadelphia Electric Company, know as PECO. The disk is smaller than most and is stampled BER (for Berwyn) P.E. CO according to the datasheet. My pic is a bit too washed out from the flash to confirm the exact stamping. It seems PECO set a number of stations in the area. There is a PECO facility just down the road, but I think the main office is in center city Phila.

I'll throw in AJ2481, a Village of Skokie mark, that I found. It seems to be part of a series of control marks that Skokie set in 2000 - time to collect them all! Although maybe I should be careful about that one near the courthouse...

The acronym for "New York City Board of Estimate and Apportionment" is "NYBE+A". See for example KU0874 and many similar ones where they are the monumenting agency. And of course that was a note where I mention this nearby non-NGS mark. KU1296 is actually a plain old CGS disk.

 

It's actually a duplicate, but this is a better picture. It's the same disk as you have for for the Staten Island Borough Hall (KV0422 "142 NYBE+A"). There you have "Appraisal" - it's the same agency. It's "Apportionment", not "Apraisal".

I thought these were already in the list but I can't find them so I'll put them in here. If you find they are in here somewhere, perhaps with a different name, sorry.

 

These are 4 different IBC Geodetic marks from the border between Maine and Canada. Since the IBC set their monuments at different sections of the border, I guessing there is a "local" style or perhaps it was a matter of when, not where. But these are certainly different from what you will see in the mid-west or Alaska. As for Mexico, I have no idea.

 

1) QH0376 IBC Boundary Monument (Maine 1845)

(click for full size)

 

2) QH0376 (non NGS mark nearby) IBC Intermediate Boundary Marker (Maine)

These are set about every .1 miles between the monuments. I think this is similar to marks in many locales, but perhaps not with the monument number and increment number on the disk as in these.

(click for full size)

 

3) QH0376 (non NGS mark nearby) IBC Bench Mark (Maine)

This was mounted on the base of the monument, and you will also see them on topos since the IBC provided the control for the USGS in these regions. I haven't found any of these in the NGS database, but there may be some in there.

New York City Board of Estimate and Apportionment

 

I was looking over BuckBrooke's web site the other day and I noticed he had included a copper bolt from one of my recent posts set by the above agency in the city-wide survey done in 1909-1914. Having interest in these marks (I'm trying to find all that are left), I thought I would add a few items here.

 

This survey used many, many chiseled squares and crosses and they also "borrowed' a good number of previously set marks from other agencies, primarily the Board of Water Supply and the Department of Public Works. Of those marks (other than chiseled marks) that were of their own, as far as I can determine there were

 

1 type of disk

4 types of copper bolts

and 1 special galvanized iron bracket (see below).

 

The information is available in great detail in the volume Precise leveling in New York City by Frederick W. Koop, published in 1914 and available in the NY Public Library.

 

The disk has already been documented on this list (see the note for KU1296). Here is some info on the others.

 

Copper bolts:

 

Here is the original figure detailing copper bolts:

 

 

There ar 2 long types (3" x 7/8") and 2 short types (2" x 5/8"). The long types have the letters "B M" embossed, and the short types do not. The ones with the horizontal bar were set in a vertical surface (as on a wall) and the bar was the actual bench mark and the ones with the dot were set on a horizontal surface (as on a step) and I suppose the pole was placed on the dot.

 

Here are samples. Sorry about the small bolts with a dot, I have only a couple of (poor) shots of that type.

 

Long type with bar (NYBE+A #748, an NGS mark KV0579 on the Custom House in lower Manhattan):

 

 

Long type with dot (NYBE+A #387, non-NGS mark near KU1296 set on a structure in Prospect Park, Brooklyn):

 

 

Short type with bar (NYBE+A #469, a non-NGS mark near KU1043 on the Williamsburg Bridge, Brooklyn):

 

 

Short type with dot (NYBE+A #488 on an old YMCA building near the Williamsburg Bridge):

 

 

Galvanized iron bracket

 

This was specifically designed by Mr. Koop and was used in the granite base of school buildings. There was almost always a chiseled mark above the bracket. The shape of the bracket is unique in that it sit on and overlaps the vertical surface and providesa a very stable base.

 

Here's the diagram:

 

 

and here's a sample, NYBE+A #847, a non-NGS mark near KU1421 on PS 158 in Manhattan (Note the chiseled 'T' above):

[Papa-Bear-NYC]

Here's one I found yesterday at the end of Throgs Neck in the Bronx NY. There is an old stone fort there (Fort Schuyler) and there used to be a lighthouse. It ws one of the triangulation stations in the 1903 triangulation of Greater NY.

 

There are two marks just south of the fort, set by the USLHS (United States Light House Service). One is decapitated but the other one is intact. I don't know when they were set. I can read "193." or "194." on the disk.

 

They were reused in 1952 by the USC&GS. The one that's intact is "A 340". Interestingly, the other one is (would have been) "Z 339". So it was the end of one level ine and the start of another at this point.

 

Here's the good one (KU0984 "A 340 USLHS")

 

Here's a close up (sorry for the fuzzy shot)

 

The other one is just a stem. Looks like the disk and some of the concrete post was sheared off, perhaps by some mowing or landscaping machinery. (KU0985 "Z 339 USLHS")

[+Organized Chaos]

I found this disk while searching for EH1385. It has the same lat/lon as the one I was looking for but does not look like the others I have found. ( Link to EH1380 that I found ) the ones I have found have the correct "Designation" stamped on them, where this one does not have the stamp T 115 like it should.

 

I can't seem to find any info on this disk. And was wondering if any of you could help me out and tell me where I can get info on this disk? It seems to be close to the measurements described by the Coast & Geodetic survey. I have not taken a tape measure out and did exact measurements on it yet. I was just wondering if this could the benchmark, or it was replaced by this one?

 

[+BuckBrooke]

I think it's a random, nearby disk, not connected with EH1385. Perhaps that's a good spot for a disk.

 

This is a US Engineer Department disk (obviously), and they don't have their disks online or in a readily accessible database, even if they have them organized. Odds are you won't find any info. It's probably associated with nearby construction, like a dam, bridge, etc.

 

Sorry about that. It is a new variant on the US Engineer Department disks; I haven't seen one from the Memphis office before.

[+Organized Chaos]

Thanks for the info Buck!

 

There is a bridge a few miles north of this marker. And state Hwy a few hundred yards or so north of it. So possibly it was placed here at the construction times of one of these. I am guessing it has something 2 do with the bridge construction. I worked in road construction for 10 years and have never saw a marker like this one. I have seen several benchmarks placed on older bridges. It also got me to wondering how common it is for a disk like this from one city and state to be placed in another city and state? This one is obviously from Memphis, TN and it is in a small town in AR.

[Papa-Bear-NYC]

I found this yesterday at Fort Totten, Queens NY. The place is an old army base dating from the 19th century. KU0978 "851 6990 TIDAL 4"

 

This disk was surveyed as a Tidal Bench Mark in 1952, but clearly it was monumented for something else by the Corps of Engineers.

 

(click for full size image)

 

I never saw a "Map Control Station" before. Has anyone seen that designation used? I assume it's some kind of horizontal control, but since maps also give elevation, maybe it was a bench mark for controlling a map's elevation data.

 

It has neither the cross usually found on a bench mark, nor the triangle used on triangulation stations.

 

Anyone know?

[+Firefighter Skippy]

2oldfarts asked me to include this mark to the list . It's LX0507.

[+BuckBrooke]

Aha. For once, I have 3 answers for three questions. Maybe it's the fact we're buying a house and I won't be able to benchmark for a while, but I feel confident...*drum roll*... In reverse order:

 

1) Firefighter Skippy, you found one of the US Geological Survey "in Cooperation with the state of" series. During the Great Depression, and shortly thereafter, the USGS did many survey projects with various states. Looking through the photo logs, it seems like they usually used a generic "In cooperation with the state" mark, such as HW0004. However, folks have photographed the variants of "in cooperation with the state of" Connecticut, Hawaii, Ohio, Pennsylvania and Los Angeles County. Links are available here. Your photo is somewhat better than the current Connecticut photo; may I use it for that page?

 

2) Papa-Bear, it seems like the circle mark (w/ variation such as the circle w/ a dot, cross in a circle, line in a circle, etc.) is the symbol for a tidal or gaging station, such as the USGS: SX1518 . The USC&GS and National Ocean Service also use the circle (w/ a line and a cross inset respectively) for tidal gaging stations. However, you're on top of surveying more than I, so...

 

Hmm, maybe I was wrong. Looking back through the list, here's a similar disk found by CallawayMT in MT: TJ0070. Maybe there's no significance to the circle. *drumming fingers*

 

3) Organized Chaos, the U.S. Engineer offices are regional, so that you're inside the Memphis office's district. Other than the occasional cross-state boundary mark (such as those found by PFF et. al.) by a state surveying office, the only specifically different city/state disks I've run across photos of are the U.S. Engineer district offices.

Thanks BuckBrooke

 

Now this makes more sense since this is a tidal bench mark. I had assumed the CGS in 1952 had just used an old USE mark when they did their surevey, but now it sounds like the Army had already used it for the same purpose.

 

As for that station in Montana, it looks like it's on a huge impoundment of the Missouri River and rather near the Fort Peck Dam, so it may be some kind of guaging station after all.

 

Have fun with your new house.
