Caves National Parks Environment.

Naturally formed Caves are wonderful geological structures. Caves are also needed for the upper environment for surface stabilization. They also provide historic information about the environmental changes of the area. Stalactites and stalagmites are beautiful formations in caves.Several minerals are also present in the caves. Recently visited the Kentucky Mammoth Caves. They are 400 mile long caves (one of the longest cave structures in the World).
