Little San Bernardino Mountains

The Little San Bernardino Mountains are a short mountain range of the Transverse Ranges, located in southern California in the United States. They extend for approximately 40 mi southeast from the San Bernardino Mountains through San Bernardino and Riverside Counties to near the northeast edge of the Salton Sink and Salton Sea.

The community of Palm Springs looks north and northeast across the Coachella Valley to the range.

Geography
The range transitions the separation from the Coachella Valley in the Colorado Desert on the south to the Mojave Desert on the north. The peaks vary in height from approximately 4,000 –. The range highpoint is Quail Mountain (California), elevation 5,813 ft. Other peaks in the range include Mount Inspiration and Eureka Peak.

Habitats
Much of the central and eastern parts of the range are within Joshua Tree National Park. Big Morongo Canyon Preserve is located in the western end of the Little San Bernardino Mountains. The oasis here contains one of the ten largest cottonwood (Populus fremontii) and red willow (Salix laevigata) Riparian zone habitats in California. It was identified as an area of concern by the Bureau of Land Management in 1982. It also has the only native palm to California, Washingtonia filifera, or the Desert fan palm which is now common in artificial landscaping.

Aqueduct
The Colorado River Aqueduct, which provides water for Los Angeles, San Bernardino, and San Diego, runs along the southwest edge of the mountains.
