Found my first benchmark today!

First outing and first attempt found DH1944. I also attempted to find the next 2 closest to that one but was unsuccessful.

 

I'm not sure what all to do at this point other than to log the find at the Groundspeak Web Site for benchmarks.

 

A lot of fun! ;)

 

A lot of fun is correct...consider yourself now hooked!

 

Congrats on your first find and log on GC.com. The log looks like a Pro's or at least someone who has done it for awhile. Great pictures also! We like to see lots of pictures - to coin a phrase of Mr. Dolphin's. :(

 

May you log many more...good hunting.

Congratulations on this find!

 

This is actually a pretty interesting station.

 

The disk was reportedly monumented (installed) in 1946, yet even in the 1946 report it says:

NOTE-- POST IS LEANING

In fact, as I've seen on some other datasheets, I think that was a later comment that somehow got appended to the 1946 report in the process of digitizing the original. hard-copy reports. (They were transcribed many years ago by federal prisoners, women I believe, who probably got something like nine cents an hour for their labors.)

 

Also, note the "stamping" line on the original datasheet:

SETTING: 7 = SET IN TOP OF CONCRETE MONUMENT

Now, notice how it got translated on the Geocaching page:

Setting: set into the top of a round concrete monument 9emphasis added]

 

As can be plainly seen in your picture, the concrete post is square, not round.

 

One more thing. You describe the station as being in "poor but usable condition." I am neither a surveyor nor a geodecist, but my understanding is that it is the position, not the physical integrity of the disk, that matters. In this case, the tilting of the whole disk-and-concrete-post assembly has presumably moved the datum point — the point measured, in this case where the horizontal and vertical lines intersect just below "G200." It may still be exactly where it was in 1946, or it may be a few millimeters or more off. But anyone doing high precision work might have sufficient doubts to go on to the next station, if I understand how these things work. (Professional correction encouraged!) So as a non-specialist I try to avoid conclusions such as whether a particular station is usable or not and just describe what I see or have other evidence for.

 

Anyway, good job, congrats again, and as 2oldfarts noted, excellent photos!
