The problem with PDs is that we are one bad year, and one big mouthed liberal asshole away from losing them to the Endangered Species act. The idiots monitor places like this, so be very careful about what you talk about concerning prairie dogs, marmots and ground squirrels.
They aren't endangered but all it takes is the right idiot to get the other idiots singing his song and we all lose. Central Wyoming has a few towns, hit the BLM or Forest Service offices in Wyoming, talk to a biologist and buy the 1 to 1000 maps.
Do yourself a favor if you want to ever use that place again, tell no one of what you found. Or it will be shot out the next time. Best bets are private land.
