We came down from Tucson to locate the geocache [url=http://www.geocaching.com/seek/cache_details.aspx?guid=c877bf58-b096-4008-83cb-8b559c04cfbd]GCR7G0[/url] so I figured we should get at least one benchmark verification enroute.

Benchmark was found per the description as the coordinates fell around 50 feet off from the actual location.

Benchmark is readable and in great condition.

Found it in the company of Elmosmelmo and ShadowAce on our way to Ramanote Peak (GCR7G0). Coords were a little ways off but made the find nonetheless.
