Saline Valley is a large, deep, and arid graben, about 27 miles (43 km) in length, in the northern Mojave Desert of California, a narrow, northwest–southeast-trending tectonic sink defined by fault-block mountains.[1] Most of it became a part of Death Valley National Park when the park was expanded in 1994. This area had previously been administered by the Bureau of Land Management. It is located northwest of Death Valley proper, south of Eureka Valley, and east of the Owens Valley. The valley's lowest elevations are about 1,000 ft (300 m) and it lies in the rain shadow of the 14,000 ft (4,300 m) Sierra Nevada range, plus the 11,000 ft (3,400 m) Inyo Mountains bordering the valley on the west.
