Searching for conservation resources...Caver hive-mind....
Is anyone aware of research or evaluation studies done on the identification of historical graffiti vs. modern graffiti? We're working with the
Bureau of Land Management to try and do a conservation project in one of their caves before the 2016 convention. ... Some informational resources would be nice.
Thanks!
