Red Rock Pass (Montana)
Red Rock Pass, el. is a mountain pass in Beaverhead County, Montana. The pass lies on the Continental Divide just north of the eastern Centennial Mountains. It separates Beaverhead County, Montana (west) from Fremont County, Idaho (east). The pass is traversed by an unimproved gravel road. On August 20, 1877 a band of Nez Perce crossed the pass en route to Yellowstone National Park during the Nez Perce War shortly after the Battle of Camas Creek.
