About the Cave
- Location: South Central Kentucky
- Mammoth Cave was created by the natural process of limestone erosion, known as karst topography.
- During this process, rain and rivers slowly dissolve and shape soft limestone, creating a vast system of caves.
- Underground rivers are still carving new passages today.
- It received its official designation as the world’s longest cave system in 1969. At the time, there were 65 miles of surveyed passageways.
