Beautiful piece of brass .... 
..in an intact sidewalk....
..with great sky. Trouble is that it's in the mid span of the old Sellwood Bridge across the Willamette River. The bridge has been moved about 40 feet from its original position to make way for a new bridge, now under construction.
Moving bridges makes for bad ties to existing stations on said bridges.
BIG OOPS!!!!:-P
Have you turned in your recovery report to NGS?
I'd recommend a POOR report with explanation. Although it is really destroyed NGS doesn't include any explanation with a destroyed log, and people may think the destroyed report is a mistake when they find the disk.

I know that mark! There is (used to be) an Army Corps bench mark by the boat landing just north of there.
> Have you turned in your recovery report to NGS?
I should do that. The old bridge will be removed in about a year, so this hazard to surveyors will be destroyed soon.
east or west side?
Oh yeah! West side, different benchmark. We tied into the "west" BM.
Do a recovery report on the NGS website, and if time allows, submitt an OPUS DB solution for it.
Be nice to get that brass when the bridge is destroyed.
I tried to get one from a USGS point on a hill that was lowered about 50ft. The dirt contractor moved it off to the side for us, concrete about 12in in dia and 3ft long. We beat on that for about 30 min with 8lb long handled sledges and didn't put a dent in the concrete so to the dump it went 🙁
That is a great piece of brass...1962 was a good year for me. Here is a time lapse of a bunch of guys destroying the positional value of that tablet.
There is a BC in a new handicap curb cut in Prineville, OR that is several inches lower than previously, somebody went to great lengths to save an old BM brass and reset it when the sidewalk was made ADA compliant, too bad it is worthless as a BM now. And yes I filled out a recovery, if you didn't know better or think too hard about why on old BM was in an ADA sidewalk you could go very far astray, it looks good! This is how you get in trouble just using a single BM to do anything!
Shelby, you just need to start a leveling campaign and put a RESET elevation on that puppy!
Buy that bridge!
You can purchase the bridge and I bet they'd throw in the disk
