Size: 30,605 acres.
Location: Imperial County; 18 miles southwest of Blythe, California (Note: Boundary set backs from roads or trails are 30 to 300 feet)
Area Description : Distinguishing this wilderness are twin buttes known as the Flat Tops, which stand out as a landmark against a range of jagged peaks. Palo Verde Peak is the high point of the range rising to 1,800 feet. Dry washes cut across the mountain slopes, supporting such vegetation as palo verde, mesquite and ironwood. Clapp Spring and its palm oasis are unique to this area, offering the only permanent water source to such wildlife species as desert bighorn sheep, desert tortoise and wild burros. Rather than hide among canyon walls as most springs in the desert, Clapp Spring lies in an
open landscape. Saguaro cactus dot the southeastern part of the wilderness, a rare plant species in California.
Getting There : To access this wilderness, take the Milpitas Wash Road exit off of State Highway 78 (approximately 12 miles south of Palo Verde). Go north and the wilderness will be east of the road.
Nonfederal Lands: Private lands lie within the wilderness area. Please respect the landowner and do not use these lands without permission.

The BLM encourages all desert recreationists and travelers exploring public lands, not only within southern California but through the west, to use propylene glycol based antifreeze/coolant in their touring and recreation vehicles. Proven safer, it will have minimal impacts on the wildlife and the environment should a leak occur.
