Rattlesnake Hills

The Rattlesnake Hills are a small mountain range located in south-central Washington state. This arid, rolling landscape features a network of rolling hills, canyons, and plateaus shaped by volcanic activity and carved by erosion over millions of years. The terrain is largely treeless, with sparse vegetation of sagebrush and bunchgrasses adapted to the region's dry, hot climate. Wildlife includes mule deer, coyotes, hawks, and rattlesnakes, the range's namesake. Despite their modest elevations, the Rattlesnake Hills offer unique geological formations, opportunities for hiking and exploration, and panoramic views of the surrounding Columbia Basin.
