group of mountains lying mainly in Inyo county, eastern California, U.S. The range forms the western wall of Death Valley. Elevations average 6,000 to 11,000 feet (2,000 to 3,000 metres); Telescope Peak, at 11,049 feet (3,368 metres), is the highest point. Some mining ghost towns are found within the range, which derives its name from a group of Shoshone Indians who once occupied the region.
