A huge cone of debris at the bottom of the sinkhole consists of everything that has ever fallen in, beginning with fragments of limestone that roofed the area and then collapsed perhaps 20,000 years ago. Some say The Springs was the spot Ponce de Leon searched for, fought for and died for, believing that here, indeed, was the Fountain of Youth.

In 1973, a scientist named Wilburn A. Cockrell brought up a nearly complete skeleton of an adult Paleo-Indian male from the 43 foot level of The Springs. Peat surrounding the skeleton was dated at 11,000 years old. No earlier intentional burial site has been found in North America.
Analysis of the skeleton put the Paleo-Indian's height at about five feet four inches and suggested a weight of 110 pounds.
Bones of Ice Age land mammals, a saber-tooth cat and a giant ground sloth, still lie below. The saber cat and a human mandible were found in a clay layer 12,000 years old and the find was the best evidence that the two species coexisted in the Western Hemisphere.
