Cave of the Mounds
Cave of the Mounds provides an exceptional illustration of two principal modes of limestone cave formation (speleogenesis): the solution of cave passageways by "vadose" water flowing above, and by "phreatic" groundwater flowing below the water table. The cave is richly decorated with cave formations of most known varieties, including stalagmites measuring 18 feet in height, and many colorful displays of mineral deposits, including pure calcite.
Year designated: 1987
