When Ocala Caverns was operating as a tourist attraction a sign stood outside the main cave entrance that told the  history and facts of the caves.

TRANSLATION OF SIGN:

“A vanished civilization utilized the series of caves, not for protection from wars but as safeguards against enormous roving herds of dinosaurs, mastodons, and gigantic sloths, also herds of reptiles.

As you enter, you will see numbered circles upon the concrete where Geiger Counters remained at every circle for exactly two minutes. The numbers are the readings in milliroentgens per hour.

Through the roof and near the left wall you can see the light of day, forty feet above that is where a rabbit rediscovered a prehistoric fortification equipped with an amazing subway system.

The roofs or ceilings throughout the entire formation are the most unique in Florida; resembling coral is however, a super-hard limerock.

The top railing of the lower catwalk is normal water level, as the water rises over the cat-walk flooring we retreat to the wharf and board an eight passenger flat bottom row boat.

Two yards beyond the far corner of the cat-walk and below the floor planking is the location of a fresh-water spring.

The primary and secondary subway systems terminate at the bridge. http://www.floridacaving.com/history-of-the-uranium-caves/Incorporated in the roof or ceiling of the primary subway is a petrified prehistoric “flying saucer”.

On the second or higher cat-walk, and seven yards beyond the stairway at shoulder height–entombed in the left, or west wall, is a petrified prehistoric enormous snake, species of anaconda.

The secondary subway systems one channel extends eighty five feet in a northeasterly direction, the front twelve yards are directly below the number two, or upper cat-walk. A steel ladder is located at the entrance of the undeveloped underpass.”
