i was wondering if anyone could tell me where i could find some info on this?

it is on the side of hwy. 30 in rainier OR. the first thing i noticed was a white sign with the letters USBM. and about a foot away was a wooden post. just about everything was worn off of it, but if you look close you will see an imprinted 83 m on it. as soon as i can figure out how to upload pics here i will do so. maybe that will help a little. thanks, culp686.

Hi Culp.

 

It is unlikely that it is a Station we use here at Geocaching, but would be handy to have Latitude and Longitude for the location though, We do have ways of looking some survey marks up. No Guarantees.

I did not see anything else in the NGS database which looked relevant to the unidentified find.

culp686 -

 

A great many (most?) of the USGS survey marks are not in the NGS/Geocaching database. The USBM sign and the wood post near it are probably both witness marks to a USGS disk (or perhaps another agency's disk).

 

I suggest using a stiff wire probe or even metal detector around and between those witness 'posts' and you might find the disk.

 

You won't be able to log it though, since it isn't on the database according to PFF's research.

ok to let you guys know. i found another one. i have pics of it on the BM list. the number if anyone wants to see is SC0466. so this one is listed. i would also like to know if it is ok to "uncover" the other one if it is burried. thanks for the help everyone.

We often find benchmarks that are a little buried by time and soil movement/deposition. Probing wires/rods and metal detectors help a lot there. The rules as I see them are:

-Don't do anything that might disturb the position of a benchmark, including soil movement that might shift it by a fraction of an inch in resettling.

-Don't damage a sensitive environment such as a preserve or somebody's well-groomed yard

-Don't take risks with buried utilities. It costs a LOT to repair them and some are dangerous to you.
