"The Devil's Millhopper" park, Gainesville, Florida
A 120-foot sinkhole with a boardwalk, small waterfalls, and a cooler ravine flora than the Florida plain around it.
Florida State Parks keeps Devil's Millhopper, a bowl-shaped sink about 120 feet deep. A boardwalk drops to springs and a miniature ravine of ferns. It is karst in collapse form, not a river cave. Ichetucknee, on another plate, is the same limestone as clear running water.
