Santa Rosa Region
The Santa Rosa Mountains in the northeast corner of Anza-Borrego Park rise 8,700 feet above the Borrego Valley desert floor, which lies between them and the San Ysidro Mountains to the southwest. The Santa Rosas were created by fault-block uplifting of the San Jacinto fault to comprise the northeastern arm of California's Penninsular Ranges Province.

This area is the most rugged and desolate region of the park, encompassing both 8,000-foot El Toro Peak and Palm Wash which lies below sea level. Lack of water and steep escarpments characterize this massive, jagged range.

Together with its sister range, the San Ysidros, the Santa Rosa prevented travel west from Los Angeles until quite recently. It wasn't until 1968 that a paved road (County Road S-22) was completed thorough the San Ysidros and across the Borrego Badlands.

The environment here is so extreme that, according to historical accounts, there were only three full-time residents of the Santa Rosa Mountains -- brothers Frank and Fred Clark and Cahuilla Indian Fig Tree John.

Because of the limited human influence in this region, a diverse plant community thrives here. Specialized plants like the Santa Rosa Sage, Parish's Larkspur and Elephant Trees flourish, as well as more common flora from Creosote shrubs to conifers.

This area is also home to more than half of the park's population of Bighorn Sheep, as well as the Western Mastiff Bat and the Pocketed Freetail Bat. Common reptiles and amphibians here include the Granite Night Lizard, the Desert Slender Salamander and the Red-spotted Toad.

No maintained or established trails or campgrounds exist in this area of the park. Backpackers are advised to register with park authorities before venturing here. Only skilled climbers attempt to climb Rabbit Peak. Car camping is allowed along any of the 15 miles of dirt roads in this sector accessible from County Road S-22 east of the town of Borrego Springs.

With more than 600,000 acres, Anza Borrego Desert State Park, has 7 unique areas that you can explore.

Anza Borrego Overview A video overview of all the fascinating places in and around Anza Borrego Desert State Park that you can visit, from the Gomphotherium Park in Borrego Springs to the Pumpkin Patch and much more! Watch this video to get an idea of the range of geologic features available to check out in the Park.

Carrizo Badlands - Video of Mud Caves and Canyon Sin Nombre The length of the mud caves varies, with some extending over 1000 feet and featuring ceilings as high as 80 feet. Caves have been reported up to 35 feet wide, and others so narrow, you have to squeeze through openings. Multi-level caves with skylights have been found, where erosion has created an opening, or sinkhole, in the ceiling of the cave. Some of the caves are fairly easy to navigate while others may require you to crawl in sections.

Fonts Point - Borrego Badlands Video
Centered in the arid Borrego Badlands due east of the Visitors Center between County Road S-22 and Route 78, four million years of geologic and paleontologic history are exhibited across a stark desert landscape. Join the crew of DesertUSA and take a road trip to Fonts Point, maybe the best place in North America to view sediments of the Pliocene and Pleistocene Epochs.
