The range, which reaches an elevation of 3,874 feet, is located in San Bernardino County, and crosses Interstate 40 between Ludlow and the Granite Mountains.

The remainder of the range is designated for Wilderness status in the proposed California Desert Protection Act of 2010.
Project Carryall, proposed in 1963 by the Atomic Energy Commission, the California Division of Highways, and the Santa Fe Railway, would have used 22 nuclear explosions to excavate a massive roadcut through the Bristol Mountains in the Mojave Desert, to accommodate construction of Interstate 40 and a new rail line. This project would have been part of Operation Plowshare if not for public opposition.
