More Info

This amazing cave was originally used by prehistoric Yokuts Indians. It was their mortuary cave where they would bring the bodies of their dead. When this tribe moved, the entrance to the cave slowly filled with debris until it was completely hidden from view.

It was in 1885 that Walter Mercer, a gold prospector, discovered the caves while resting from the summer heat. Mercer had apparently found a tiny hole, not much bigger than a fist, which was sending up cool air. After dropping a rock down the hole, he realized the rock had taken a very long time to reach the bottom. Excited and very curious, Mercer returned later with candles and ropes, exploring further and making it into what is now known as Gothic Chamber.
