On property of Richardson's Rock Ranch, west end of Blue Mountains. Trout Creek (trib of Deschutes River) drainage.
Snake was ~ 60 cm (2 feet) long.
If you look closely, you can see the rattlesnake in the photo!
Neighbors discovered it laying still in the dappled shade of their backyard.
My second close encounter of the year.
Crotalus is a genus of venomous pit vipers found only in the Americas from southern Canada to northern Argentina. The name is derived from the Greek word krotalon, which means "rattle" or "castanet", and refers to the rattle on the end of the tail which makes this group (genera Crotalus and Sistrurus) so distinctive. 32 species are currently recognized.
