Disk Logo List


Black Dog Trackers

Recommended Posts

I was in Woods Hole Massachusetts last weekend and logged a few tidal bench marks. One (LW1577 "844 7930 TIDAL 7") was dated 1913 and it's the earliest USC&GS disk I have found (although I've found an earlier USC&GS "marking bolt").

 

It's remarkably similar to later disks. It looks like the standard tidal b.m. disk minus the circle around the center bench line. And interestingly, although it's the oldest of the surviving marks at the site, it was number 7! I wonder what happened to the original 1 - 6? Probably some of those were chiseled squares, crosses, bolts, etc.

 

Here's a picture:

Anyone know when the USC&GS started using these disks? What's the ealiest USC&GS disk anyone here has found? I know the USGS used disks very similar to today's by 1900 (I logged one last month in Maine which was discussed in another thread).

 

Buckbrook: is this a new type for your list, or have you got one like this before?

A couple more for the list. Both found on July 4th in St. Joseph, MO

 

KE0381 - Monumented by "RBNF" [Researched But Not Found]. I assume it was the CB&Q Railroad or the State Hwy Dept. Both would be interested in the clearance between the rail and the overpass.

 

AD9796 - Missouri Dept of Natural Resources. Not really a disk, but a 8-sided piece of metal (copper?).

I was recently hinking and benchmarking on and near the NH/Qebec border as well as the Maine/Quebec border.

 

I recoverd an IBC station (QH0523) which was marked by an IBC disk I had not seen before. It was a standard sized disk (unlike the small 2 inch triangulations stations and bench mark disks I am used to seeing up there). It is mounted on the top of a cut off cast iron boundary monument. It looks like they kept repairing the thing and finally gave up, cut it off and mounted this tablet on the top of the stump. Only the disk is visible (with an outline of the old cast iron post).

 

Since it was right by some one's lawn, I didnt want to do any unneccessary digging to see the stump or original base. It's also a bit warped, but otherwise in good condition.

 

Here's a picture (sorry it's a little overexposed):

OK, I caught up on everyone's additions and emails submissions to me. There was one in another forum topic; I'm trying to track it down. Here are some additions:

As a request, please look through agencies that I have listed, but that don't have photoes. If any are near you, would you mind going over to find them, and snap a photo? Many are found, many are not found.

So, where's the official list to search for nearby ones to find for you?

 

 

Harry Dolphin; Scroll down the page at BuckBrooke's Master Agency List and you will find a section for discs that are recorded as found/recovered without photos and another section for discs that have not been found or recovered but indicate a unique disc somewhere in the discription.

 

BuckBrooke; I checked on the submissions update and the Lane County Surveyors disc (OR) carries the same designation as the Lane County Public Works disc right above it. It links to the correct photo though.

 

Thanks for the list and for your work in updating it.

Waymarking disks I haven't seen, and can't find after searching, but have been added to the agency list:

That brings the total to about 820

I just looked at your master list, and was impressed to see that you already had a disk that I logged on 9/18/06. (AE6516) Although it is a cadastral disk, marking a corner of the Appalachian National Scenic Trail Exterior Corridor Boundary, it was subsequently used by the VT Agency of Transportation for control on a bridge project just down the road. That's how it got into the NSRS (National Spatial Reference System).

 

There are literally thousands of these disks along the 2100+ mile length of the AT. I am personally responsible for the placing of several hundred of them here in Vermont. I would be interested to know if any others have found their way into the NSRS.

 

For further database info, the government agency that contracted these surveys is the US Department of the Interior, National Park Service.

Holtie22,

I'm reasonably involved with the AT disks on the corridors. I'm working with Sally Naser to make a useful online database; we started discussions just as my old dissertation topic fell through this spring; I've settled personal matters, and will be getting going on it soon. Send me an email.

My impression is that only a handful of the AT disks are in the NGS database; text searching through the appropriate state PID text files found 2 or 3, as I recall when I was going through the databases this spring.

 

Cheers,

Buckner

I recovered a couple of state boundary line monuments over Columbus weekend.

 

Vermont-New Hampshire Reference Monument No. 84, This is non-NGS, but I put up the photo with QH0734 "BOUNDARY REF MON 86" which is just down the road. No. 84 is in better shape so the picture is a better one to use.

 

8c64fd6a-dff4-4d36-9b5e-73820871068e.jpg

 

Maine-New Hampshire Boundary Monumewnt No. 118. This is also non-NGS but I put the photo with a nearby station (which I didn't find) QH0543 "RUMP IBC". The boundary monument was on the west slope of Rump Mountain (on the summit of which the IBC station was supposed to be). I believe there are some ME-NH monuments in the NGS database, further south. The initials "ATF" appear at the bottom right - anyone know what they might stand for?

[Edit: I found an NGS ME-NH marker - PF0498. "ATF' seems to be on all of them. It may be the agency that set the marks.]

Hi Buck,

 

Being the one who took the photo, I have no idea what the marker is for. It may not even be a survey marker. I'm still trying to research it. I haven't had time to contact the company (WTU). The location is San Angelo, TX and WTU is West Texas Utilities Company.

Ok, I've updated the above submissions. Here are a few more, gleaned from the usual sources. Also, a dozen corrections/improved photos/rearrangements to the list.

 

As usual, the largest number found are in California. Are there more people getting out and hiking there? Anyways, I've noticed that a fair number of the MN counties seem to have their own disks. Anybody from MN, could you verify this, and maybe supply a few more photos?

Hi,

My sons and I started geocaching only a few weeks ago. However, while reviewing video / pictures from one of our camping / ghosttown trips this last summer, we found the attached picture. I assume it is a benchmark of some kind. We took this picture at the top of the Happy Jack Chalk Mine near Scotia NE. I thought you might find it interesting. If you know any more about this particular item, we would be interested to learn. I have also included a picture of the view from the peak (2000 feet is high for Nebraska), above the chalk mine (north loup river).

 

Since I could not figure out how to upload pictures, please see them at my yahoo photos:

 

http://photos.yahoo.com/sorensenteach

 

they are in the happyjack album.

Thanks, everybody; I'll try to put them in this weekend. I'm not spending as much time on benchmarking as I used to, as I got a fellowship to finish my dissertation and am commuting 160 miles/day (80 each way). Kind of takes the fun out of driving on the weekends. Also, my days are longer.

 

As a fun note, I'm making images of bipolar jet flows coming out of evolved stars. Tip to tip on the lobes of the stars is 350 milli-arcseconds with pixel size of at worst 100 micro-arcseconds. I should be able to measure parallaxes in the next year of 50 uas with 5 sigma accuracay (all the way across the galaxy).
