Limestone Caves

Learn About Caves!

Most caves are solutional caves, often called limestone caves for the common type of soluble rock in which they form. The caves form as groundwater dissolves quantities of soluble rock by seeping along joints and faults.

Protecting Caves


Take Nothing but Pictures.
Leave nothing but footprints.
Kill nothing but time.

Cave Conservation is a very important part of cave exploring and show cave visitation. Caves are very fragile and it could take thousands of years, if ever, to repair any damage caused by careless cavers and visitors. Also there are laws in all states that make it illegal to damage or remove anything that is in the cave including formations, any animals that you may encounter while in a cave, or any of the other parts of the cave that is in its' natural state.
