Rickwood Caverns is maintained by Alabama as an operational caving park, an underground "miracle mile" composed of magnificent passages and beautifully lighted rooms, accented with thousands of sparkling white limestone formations. The caverns themselves were water-formed during the Mississippian period over 260 million years ago. Rickwood Caverns still contains active "living formations," as mineral-laden water droplets build colorful structures and flowstones. Rickwood Cave reveals that it was carved from an ocean bed - shell fragments and fossils of marine life are clearly visible along the cavern ceiling and walls. Many curiosities are featured on guided tours of the "miracle mile" at Rickwood Caverns State Park.
