ArtMan -

 

My suggestion means the second of your scenarios (currently).

 

I'm not sure what "formal" might mean, but some type of naming should be used, I think, just like in cataloging coins, stamps, beer cans, or whatever. Systems of naming and numbering are commonly used for organizing the types of a thing observed.

 

As this list matures, it should probably be re-worked from time to time. Currently, it has approximately 3 fields - example PID, State, agency name as written on the disk. It should be re-worked at some point, perhaps using 5 fields; example PID, State, the agency name, how the agency name is actually written on the disk, and type (by chronological order of manufacture/monumentation date).

 

Currently, the types, whether or not they say "Type X" as I suggested, are not in chronological order of manufacture/monumentation date because we don't know all the dates that are included in the NGS/geocaching database. They are currently in either alphabetical order or by the chronology of our adding them to the list, or some other semi-random order.

 

In reality, there can be no real formality here in the sense of seriousness because the entire concept of a putting together an 'agency list' of these disks is in the category of Fun. :P

I am new to this so if this information is available somewhere, point me in the right direction. I have a marker on my property that is marked US Deptartment of Interion Geological Survey. The center of the disk has 193 HLZ inscribed, and is dated 1969. Can someone tell me what this is, or where I can find more info on it?

AI6802 (OH) Clinton County Engineer Survey

Where's the log entry and photo? I thought this was supposed to be a list of disks that had actually been found, so that we could see the logo on the disk and verify that it was something different from all the others?

I thought that too.

I thought it was discs we(I)found and documented.

Not just a list of the different agencies.

Link to comment

The issue here was that I have two files, one that builds up my changes for the forum, and the actual web page. I put the potential not photo documented PID in the forum file, and then ran across a real photo later, and put the new, correct PID onto the website. Here is the correct PID:

 

AI6754 (OH) Clinton County

 

It's not a great photo, but good enough to see the 2000 15 stamping, from the datasheet. Thanks for catching the slip-up.

 

Cbeelow, this is a topic that occurs often when someone runs across a disk. Please read the Frequently Asked Questions that Black Dog Trackers et al. put together. Do a search around your property in the Goecaching benchmark database. Try clicking on "other search options", and doing a search on "193 HLZ", for the designation. It's clearly a US Dep. of Interior Geological Survey, but you already knew that. If it's not in the database, then...it's not there. There's a lot of disks out there, and only a few are in the database. If those answers don't help you, please come back and we'll help some more.

I believe that might be more properly ID'd as a U.S. Navy disk, though.

 

At any rate, I am not familiar with the symbol used in the center. Any idea what the arrow is pointing at?

Well, NAVY DEPARTMENT and BUREAU OF ORDNANCE are both stamped on the disk, but I take your point. Possibly NAVY BUREAU OF ORDNANCE might be a good solution.

 

I honestly didn't even notice the arrow piercing the triangle until you mentioned it. I believe the arrow is pointing more or less to the east, but I didn't notice it in the field (a blazing hot day with sweat pouring into my eyes), and other than the rotting pier, I don't recall seeing anything notable offshore. (It's probably only 100 yards to the waterline, and I don't think it's pointing to anything on land.

 

This whole area is downrange from the Dahlgren Naval Surface Warfare Center, and I'm guessing it has something to do with that, but as to the arrow-through-triangle symbol, I'm clueless.

Note that EW7261 from BDT's last batch is Los Angeles County Surveyor

For EW7399, it looks like they just adjusted the inner ring printing slightly for a reference disc vs. a station disc. Probably shouldn't be included.

 

Pursuant to BDT's comment on the misidentification, and some other stations I've run across like this, I'm starting a new category on the list for pictures of agencies that aren't in the NGS database, but one of their discs was photographed and posted on another station's PID page on Geocaching.

 

Here are two more:

AR1765 (FL) Alachua County

AK6381 (US) U.S. Engineer - Channel Reference

Yes, I submitted it as just "County Surveyor" because that's all that was on the disk.

 

This is an example of where the current format leads to some problems - there is often a difference between what is printed on a disk type and what the agency name really is. Then, there's agencies that have changed their name! I think that what's actually printed on the disk is the most important to us.

 

For listing by agency, you want to feature (sort by) the real agency name. For comparing a given disk to the database to see if it's a match of any of them, you want to feature (sort by) exactly what's written on the disk. In this case, "County Surveyor" is not the same as "Los Angeles County Surveyor", although probably both kinds exist in the NGS database, and in this case, the disk is "County Surveyor" even though we can figure out which county it is.

 

As I was suggesting before,

using 5 fields; example PID, State, the agency name, how the agency name is actually written on the disk, and type (by chronological order of manufacture/monumentation date).

might be the way to go. In this case (imagining more than one type):

EW7261(CA) County Surveyor [Los Angeles County Surveyor] {Type II}

where the agency name is in [these]. One could say that the agency is just [Los Angeles County].

 

Since our main interest (I think) is what the different disks actually say, the sort should be (I suggest) on what the disk says primarily, and actual agency name secondarily. Both should still be secondary to the (State), I think.

 

But then...... I'm not doing the web page. :rolleyes:

As a test, I manually went through Arizona by the MARK LOGO field in the PIDs. That gave a lot of agencies, a number of which haven't been photoed yet. Those are in the secondary catalog. As another project idea, I can probably go write a Matlab script to give me all of the different MARK LOGOs in each state file I've created. Then, I can search back through for each one, avoiding having to look at each benchmark.

Trying a slightly different format:

I tried {Agency Name} too, but it was a copy of the Literal Marking 90% of the time.

 

Anyway, here's some more types ......

Which states seem to have no types? MS, ND, OK, UT.

BDT.....I just recovered PH0294 last week. It may not be on the NGS list yet but my log and pix are on GC.

 

I considered this another of the Maine-New Hampshire Border Commision marks.

 

Do you mean to say this is different from my earlier ATF finds?

There's starting to be a large list of agencies in the database that have discs but don't have pictures. There's ~322 w/ pictures, and 37 w/out pictures and maybe another 9.

I saw a listing for the US Mexico Boundary Commission, but I didn't see the US- Canada version:

 

http://www.geocaching.com/mark/details.aspx?PID=QF0036 - International Boundary Commission. Unfortunately, while I found one, it is in poor condition - only the stem remains on the side of the building, which has characters embossed. Maybe someone else has one in good condition?

 

Another one is the Boston Planning Board. There are many, but the vast majority seem to be on top of buildings (therefore, unreachable). I found one as a reference disk to another disk. Do reference disks count for this listing?

Link to comment

The US-Canada Boundary Commission is on the list, right above the US Mexico BC, as:

OF0961 (US) United States Canada International Boundary Commission

 

However, there may be a Type II that we haven't seen.

 

As for agencies that are not in the Geocaching database, or are in there but unaccessible, you could post a photo of a disc that's near another PID, and we'll reference it in the auxiliary lists at the bottom. Might be at the top...have to think about this.

Here's a few more, without links. Sorry. The double stars are discs that are placed by an agency but don't actually have the agency's name on them. I'm not sure they should be included. Single stars are discs where the agency name wasn't premoulded onto the disc, but was hand stamped before putting it into the ground.

I went up to the city (i.e., San Francisco) tonight for a party at the Presidio, which is no longer an Army base, but now part of the Golden Gate National Recreation Area (GGNRA). I decided to stop on the way and look for HT2259, which has been found by geocachers a few times, but not officially recovered for nearly 30 years.

 

The reason I'm posting about it in this thread is because I can't find any other references to this type of survey mark. The outside ring of text says, "UNITED STATES OF AMERICA • NATIONAL CEMETERY." Inside that, it says, "DEPARTMENT OF THE ARMY • OFFICE QM GEN." And the middle ring says, "$100 FINE FOR DISTURBING." Then there's the stamping "33" and "1961."

 

I was just about to post a query about the middle ring of text, because it looked like "OM GEN" to me. But then I got an inspiration, and sure enough, it's "QM"--i.e., quartermaster. I just found a GGNRA web page that verifies that the Presidio cemetery used to be under the control of the Quartermaster General of the U.S. Army. (I guess the QM General's office manages all the national cemeteries?)

 

That page mentions that the Army had plans in 1961 to expand the cemetery, but they fell through. Since this mark is about 1/10 mile from the corner of the cemetery area, I'm guessing that it may have been placed to indicate one of the proposed future corners of the expanded site. I wonder whether there are more of these from 1961. No others are listed in the NGS database.

 

You can see my photo of this mark on my website. It was dark when I found it, so I'm afraid the flash on my camera provided rather flat lighting. However, I may be back in the city next month, so will try to get some daylight shots.

 

Anyway, although the NGS datasheet simply lists the monumenting agency as "USA", this one is different from all the Army Corps. of Engineers benchmarks. So I guess we'd call this "USA-QM GEN".
