I found a survey disk right at a cache site, but then found it was not on gc.com or Waymarking.com. It looked like the few others I had seen, and I "think" it was US government, but I am not positive.
The physical coords are identical as cache GCPDDM, "Bridge at Algerine Wild Area". It is mounted on the concrete support of the bridge, northwest corner, a disk as I mentioned earlier. It had the following markings on it:
ET15WAC
I'm not sure what I can do about this, just curious. Anyone else have any ideas?
