I encountered a beautiful 34" yellow phase timber crossing a gravel road off of St. Rt. 144 in Clinton Co. on 5/29/16. Got a nice video of it out in the open buzzing at me.
Here's the Fish Commission's reference to 600 rattler dens:
"In the late 1980s and early 1990s, Commission non-
game biologists began compiling more refined location
information from amateur and professional herpetolo-
gists concerned with the conservation of Pennsylvania’s
timber rattlesnakes. Over 600 historic rattlesnake “dens”
were mapped in Pennsylvania."

The Virginia Herpetelogical Society quotes research that surveyed 115 timber dens in VA and MD. The population of most of these dens ranged from 30-60 individuals.
Based on these metrics, I'd make a SWAG and say there are 18,000 to 36,000 timber rattlesnakes in PA.
