The wilderness is a sloping area of 13,261 acres (53.67 km2), ranging from 2,000 ft (610 m) elevation in the south to 4,000 ft (1,200 m) in the north. It is situated entirely in California, bordered by the Hauser Wilderness to the south.[2] Vegetation consists primarily of chaparral (dominated by chamise and scrub oak) with oak woodland along stream bottoms.[3]
Wilderness permits are required for both day and overnight use.[3]
