Notes
On a warm summer evening, this small adult specimen was found crossing a paved road in the Crooked River drainage, near Post. In this area of Oregon where the open sagebrush country of the Great Basin meets the forested Blue Mountains, all rattlesnakes have a blended mixture of oreganus and lutosus characteristics (this one trending more towards oreganus). The 50 to 75 mile wide zone of intergradation between the two subspecies runs eastward from the Bend area for about 300 miles to the Snake River near Baker City.
