not my originals. tried to find photog for credit, but all I got is many friends removed and location near golder ranch rd (catalina state park area). doubt it's wyoming, but certainly could be somewhere else. regardless, a spectacular labyrinth of vipers!
and yes mark, 'body-slam it!' was the first thing that came to mind.
Herp geek addition: these appear to be Crotalus viridis viridis (common prairie rattlesnake). I suspect these were photographed either in colorado or southern wyomoing. what does this have to do with climbing? oh yeah, watch that next hand hold!!!!
