The Dead Mountains are a mountain range in the southeastern Mojave Desert, in San Bernardino County, California. The range borders the tri-state intersection of Nevada, Arizona and California, and the Mohave Valley, with the Fort Mojave Indian Reservation bordering the range foothills on the east and northeast, in the three states. The Dead Mountains are 12 miles (19 km) northwest of Needles, California. They border the Colorado River on the east, and the Piute Wash of the Piute Valley on the west. Piute wash drains south, then turns east for 8 mi at the south of the range to meet the Colorado River.
