Notes
On a warm summer evening following a brief thunderstorm, this nice specimen was found crossing a gravel road in the Bear Creek drainage, east of Bend. 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. 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.
