Mud Caves, Show cave system in Anza-Borrego Desert State Park, United States.
The Mud Caves are a show cave system in Anza-Borrego Desert State Park formed from ancient silt and mud deposits carved out by water erosion. The passages wind through various chambers where you walk and crawl through natural corridors.
The cave system developed over millions of years when this region was covered by an ancient lake that gradually dried up. The silt layers deposited on the lake bed were carved away by flowing water and wind erosion.
These caves attract geological researchers and outdoor enthusiasts who document and explore various named passages, including Chasm Cave and Plunge Pool Cave.
Exploring requires protective gear like helmets and lights since passages are low and narrow in places. Good gripping shoes are important because the muddy ground can be slippery.
The caves are known for having partially open ceilings where natural light filters into the chambers. These openings create surprising moments when daylight suddenly illuminates what would otherwise be dark spaces.
