Little Salt Spring is a feature of the karst topography of Florida, specifically an example of a sinkhole.It is classified as a third magnitude spring. [4] The numerous deep vents at the bottom of the sinkhole feed oxygen-depleted groundwater into it, producing an anoxic environment below a depth of about 5 m (16.4 ft). [4]
Devil's Millhopper is unique in Florida in terms of its scale; over 100 feet (30 m) of rock layers are exposed. [2] The cutaway, limestone sides of the sinkhole provide an easily visible geological record of the area. Twelve springs, some more visible than others, feed the pond at the bottom of the sinkhole. In the summer, the bottom of the ...

Warm Mineral Springs is a sinkhole formed in carbonate rock by the collapse of the roof of a cavern 30,000 years ago. The land surrounding the sinkhole is flat, and about 3 metres (10 ft) above mean sea level. The circular opening of the sinkhole at the current water level is 72 metres (236 ft) across.

Lake Jackson is a shallow, prairie lake on the north side of Leon County, Florida, United States, near Tallahassee, with two major depressions or sinkholes known as Porter Sink and Lime Sink. The lake is located in the Red Hills Region, and has fluctuated from periods of being dry to a maximum elevation of 96 feet (29 m) above sea level.
