Indian Pass Wilderness is a 32,418-acre protected area in southeastern California, managed by the Bureau of Land Management in the far southeastern Chocolate Mountains west of the Colorado River. It adjoins Picacho Peak Wilderness on the south and the Imperial National Wildlife Refuge on the east. The landscape is centered on Julian Wash, which drains toward the Colorado River and lends the region the name Julian Wash Country. Quartz Peak rises to 2,126 feet in the western part of the wilderness. Its desert habitat supports species such as desert bighorn sheep, Colorado River toads, and wild burros.
