Anza Borrego - Borrego Badlands
Conglomerates, sandstones, claystones and mudstones, compressed and hardened, chronicle a variety of landscapes, fossil life forms and climates that no longer exist at Anza-Borrego. This spectacular area, with its arid rocky geography, sunken mesas and corrugated hills of dry mud, is called the Badlands of Anza Borrego.

 

Carrizo Badlands - Mud Caves

Carrizo Badlands - 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.
