Can't Find Benchmark in Database
This weekend, I found a benchmark (or what I believe to be a benchmark). However, when I went to log it, I couldn't find this particular one listed in the NGS database.
I have tried using the geocaching.com search funtion to search by designation, but had no luck, and none of the nearby marks match this location or description. Is it possible that this one is not in the database?
What's your method for logging benchmarks when you find them by "accident"?
**EDIT: Here's a picture of the one I found. On second look, I see that it is stamped "Corps of Engineers". Is this why I'm not finding it in the NGS database?
