Devil’s Den: a Pleistocene Epoch Karst – Underwater Snapshots

Williston, Florida is home to Devil’s Den. The karst is more commonly known as a “hole” to common folk. This scuba diving wonderland is part of the Florida/Georgia aquifer. The hole provides direct access to the aquifer below. Devil’s Den is characterized by limestone deposits which date back as far as the Pleistocene epoch (2 million to 10 million years ago) .

Cave History

The cave itself is 10,000 – 75,000 years old. It once boasted an extinct bear skeleton, which is now on display at the University of Florida Natural History Museum. Today, millions of other fossils are still embedded in the limestone at Devil’s Den for scuba divers and snorkelers to see. There is a large fossil that could possibly be a whale vertebrae.

In the past, this area has served as a swimming hole. The Devil’s Den was once the bane of a farmer who had to chase party animals off their property. The cave was also once a dump. Now, Devil’s Den is a delightful and clean place for snorkeling, scuba diving and dive training.
