NGS Disks in 1971

[NGS Surveyor]

Has anyone found any type of NGS disk stamped 1971? Since NOAA (and thus NGS) was formed late in 1970, I wouldn’t expect to find any 1970 NGS disks. I have seen a photo of a 1972 NGS disk, but the question remains, were any NGS disks set during 1971?

 

Thanks,

FV1049, FV1050, and FV1051

 

No logs or recoveries or pix yet but the datasheets say they are stamped 1971.

billwallace, Thanks. But the problem is that these may well have been USC&GS disks stamped 1971 rather than NGS disks stamped 1971. Some time ago I had one of our "database guys" do a search for me and we came up with the same problem - there are lots of disks stamped "1971" but from reading the description you may not be able to tell if they are USC&GS or NGS.

I used GSAK to filter out the benchmarks that have a 1971 monument date locally. After reading up on the few it showed as having a 1971 stamped on the disk itself, there are some I may go try to recover and see exactly what kind of disks they are. If I can find a NGS disk, I'll let you know (along with a pic).

 

It appears that the majority of everything monumented in 1971 around here were intersection stations.

George--

 

Yes, we had a moment of excitement over a 1971 stamping, but it was a USC&GS disk. Good luck.

Here's one: CZ1945 PASS RM 3. After a database search and review of NGS marks set in Arizona in 1971, it looks like this is the only one in the state with a photo on gc.com that is the NGS disk, all the others were USC&GS disks.

I looked in the data for MONUMENTED NGS and found 6,040 disk type markers monumented 1971 or earlier.

 

The champion of them all is AE9127, a traverse disk "monumented" by the NGS in 1852.

I guess almost all of these [ Condition: MONUMENTED, Report By: NGS ] mean not actually monumented by NGS but .... something else.

Did they even HAVE Traverse Station Disks in 1852?

 

I have seen a few reports like that. they seem similar to Papa Bear's lazarus resurrections, where the NGS team recovers a mark based on a published report of a mark not yet in the database, and gives the date of monumentation as the original date...but yet somehow their recovery also takes that date.

There is a 1972 Level run in the UP of Michigan that still used USC&GS disks, not NGS.

southpawaz, That is exactly what I was looking for, thanks! I have changed my survey marks paper to state that NGS disks were first used in 1971 (formerly stated “circa 1972”). I also added “southpawaz” to my list of credits for information.

 

AZcachemeister, USC&GS started using disks c1900 and TRAVERSE STATION disks in particular c1924. The USGS started used disks a few years earlier. Often USC&GS set disks to replace marks that were originally a drill hole, chiseled cross, or something else. The stamping should have included the original date and the remarking date but that was not always the case in the early years.

 

Z15, Yes, USC&GS disks were frequently used for several years into the 1970s, and occasionally even later.
