Hollow Ridge Cave is a few miles northeast of Marianna, Florida, in a small hill that rises about 40 feet above the Chipola River flood plain. The cave has four entrances and a surveyed length of 3,370 feet, making it one of the larger caves in the area. It is formed at the contact between the Marianna Limestone and the Bumpnose member of the underlying Crystal River Limestone. The cave’s passages are a mixture of narrow fissures and muddy bedding plane crawls connecting several rooms. Many formations are found throughout the cave. The lower levers are subjected to frequent flooding.
Upper Entrance, Hollow Ridge Cave Visitors are warned that during or following heavy rains the cave may flood. The SCCi recommends that cavers not enter the cave when rain is expected. Flooding can occur very quickly and with little or no warning!
The surface areas of the preserve are wooded, with abundant growth of pine, cedar, hickory, and other trees typical to the region. A small, grassy clearing at the top of the hill serves as a parking area for visitors. Near the back of the preserve there is a small quarry, long abandoned and now overgrown with cedars, ferns, and oak-leaf hydrangeas. The Chipola river lies about 1,500 feet to the west and is fed by many springs in the area. The parking area is reached by a short dirt road and driveway. The donation of the property was complicated by overlapping boundary lines and related title issues.
