We're fairly new to geocaching and even newer to the world of benchmarks. While placing a geocache in a remote hiltop area, we noticed a witness post. Further investigation, and several trips later for tools has produced our first "buried" benchmark. See pic. We carefully cleaned it off and took pics, but I can't seem to figure out how to look it up. A search on geocaching.com's benchmark page returned one result for 145 HLZ but its in SC and we are in PA. Am I dealing with "apples and oranges" here or am I missing something?
