Natural Features Description:

Sinkhole ponds such as this are formed by the slow dissolution of limestone or dolomite bedrock below or the sudden collapse of a cave below. Sinkholes are found in karst landscapes that also have caves and springs. Over time this sinkhole filled with silt and clay particles and decaying vegetation allowing it to seasonally hold water. In the spring the western chorus frog and spring peepers can be heard. Sinkhole ponds are important breeding habitat for a number of frog, salamander and insect species. Growing in this pond are a number of rare or uncommon plant species. One of these, the epiphytic sedge, is more commonly found growing at the base of bald cypress trees in southeastern swamps. A number of the plant species found in Ozark sinkhole ponds have their centers of distribution in the southeastern coastal plain.
