Mud Caves

The Mud Caves are a popular feature in Anza Borrego Desert State Park in San Diego County, California. The caves, located in the Carrizo Badlands, along the Arroyo Tapiado, were created by water flowing through a thick deposit of silt and are an example of pseudokarst topography. There are at least 22 caves, some up to 1,000 feet (300 m) in length and 80 feet (24 m) in height.^[1] Many of the caves are easily accessed.
