This was a great day of Jeeping in Anza Borrego. It was just by coincidence that we met up with this great group of folks. We started at Canyon Sin Nombre, headed past the Mud Caves, down Diablo Drop Off and finished at the end of Fish Creek Wash. 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 in length and 80 feet in height. Many of the caves are easily accessed.
