Mammoth Cave is a limestone cave system, located in Kentucky, USA. It is a type of karst landscape, characterized by the dissolution of soluble rocks like limestone, resulting in unique underground formations and passageways.
Mammoth cave began forming about 10 million years ago when an ancient sea covering the central United States disappeared and erosional forces let cracks and holes expose the limestone that was beneath the sea. Rainwater began to get underground and hallowed out the cave.
Mammoth cave is underground in Kentucky (most of it is in Edmondson County) and it is centered around the Green River. It is the longest known cave system in the world.

Mammoth Cave is a cave in Kentucky that is underground and is under a forest. Pioneers found Mammoth cave in the early 1700s. Some of the events that happen there is Wildflower Weekend and National Juniur Ranger day in April and The Cave Sing in December.I have not been there but I hope I do some day because Mammoth Cave (in my research) seems to be a very nice place to be! Mammoth Cave is located in Cave City, Kentucky. It got its name because it is so big, and the Mammoth was also very big. +++ Caves ARE underground - by definition! Actually the locals "found" it thousands of years ago, and used it as a dwelling etc. Big: though not especially deep at about 380 feet, the entire system has somewhere over 350 miles of surveyed passages, making it the world's longest. It and its location are now a National Park, I believe.
