Carved by water from Edwards limestone, cave lies along the Balcones Fault and is estimated to be 100 million years old. 95 percent of formations are still growing. Cave was apparently open during late Pleistocene (20,000 - 45,000 years ago), for bones of many extinct mammals have been found in debris cones filling former natural entrances. Remains of sabre-toothed cats and mammoths are represented. (1973)
