If you have a question or a comment about this photograph you may write to me at: tas4@schweich.com I sometimes post interesting questions in my FAQ, but I never disclose your full name or address.
  Colorado, Jefferson County, North Table Mountain, North Table Mountain
Photographed 8 October 2014.

This bench mark is badly vandalized. There are two reference marks nearby but I think this is the bench mark because it alone has a date stamped on it.
