Wakulla Springs — Andy Duncan

Wakulla Springs, in the deep jungle of the Florida panhandle, is the deepest submerged freshwater cave system in the world. In its unfathomable depths, a variety of curious creatures have left a record of their coming, of their struggle to survive, and of their eventual end. And that's just the local human beings over the last seventy-five years. Then there are the prehistoric creatures...and, just maybe, something else.

Ranging from the late 1930s to the present day, "Wakulla Springs" is a tour de force of the human, the strange, and the miraculous.
