Help me identify this NGS mark!

Over the last weekend, I found this mark near my hometown that is clearly NGS, so should be in the database, but I can find no mention of it. Can somebody help me to identify this mark?

I found it at N39 11.625 W123 12.416

 

I'm pretty sure that the text that is hard to read says FORKS since that is the nickname of the area that it was, but it looks kinda like FORD also.

 

 

Thanks!

Looks to me like it's probably reference mark 2 for KT2014, which was last reported as not found in 1980.

 

Southpawaz nailed it. It should be the reference mark 2 for the triangulation station Ford. It says 'reference mark' on the righthand side of the disk.

George has an excellent tutorial on triangulation stations, and what kind of disks (with their purposes in a set) that is pinned at the very top of the benchmark forums here. It will help explain (and show) what the reference mark disks are. Sometimes a reference mark disk can have it's own separate PID datasheet, but most of the time they don't.

I only see one NOT FOUND recovery (1980), and wonder if the previous logger made a serious search for RM 1 and the UNDERGROUND station. kayakbird

 

'Recovery notes of 1977 and 1980 say the mark was searched for but not found.'

I was a bit pressed for time when I posted this morning. Found it by converting your coordinates to DMS and plugging in to the NGS Radial Search function.

Hmm, I did that only on Geocaching.com, and wasn't able to come up with what I wanted.

 

You used the Advanced Search on Gc.com and it didn't work for you? That's odd. I just tried it with your coordinates, and this one was at the top of the results:

 

KT2014 0mi N FORD CA

 

The data sheet on the page for that mark says, "REFERENCE MARK NUMBER 2 IS A STANDARD DISK STAMPED FORD NO 2 1949 SET IN THE TOP OF A 10-INCH SQUARE CONCRETE POST THAT PROJECTS ABOUT 5 INCHES ABOVE THE GROUND."
