Mud Caves of Arroyo Tapiado
One of the more unusual trips to be found in the Anza Borrego are the Arroyo Tapiado Mud Caves. Though mud caves can be found in other areas, this is one of the largest concentration of over 42 caves. They span the range of large to small, some easy, some difficult.
One must be careful though and beware of ones safety, a recent death in Hidden Cave drives this home. Don't go alone or out of ones comfort zone. The smaller caves should be left to the more experienced.
One also must pay attention to the roads in and out to the Mud Caves, there is quite the off road network in the Anza Borrego, and if you miss your turns you can find yourself in a bit of trouble. The road markers are iffy at best and are sometimes stolen. I will be adding to this page as there is a lot of photos to process. High clearance vehicles and 4X are the best to travel in.
Warning: The area is covered in a extremely fine dust, during winds it really kicks up, see later pictures, in the caves it always present in the air. Anyone with breathing problems need to take precautions.

Two Caves Careys Mud and Chasm, Careys Mud not to be confused with Careys Big Mud, is rommy with huge passages and Chambers. Chasm is still roomy but you need to watch your head in this one.

Heres a point of reminder, caves are unpredictable, this section has recently collapsed. This is evident by the light colored rock. The collapse has now created a skylight to the surface.
If you look at the picture closely, one can see the point of failure. Though water plays its part, this was most likely caused by the small white crystals on the wall in the background. I have posted a photo of the crystals farther down the page.
