Mammoth Cave National Park in Kentucky includes the most extensive cave system
known in the world. More than 367 miles of cave passageways have been mapped, and
there may be more miles still uncharted. The national park preserves this cave system
along with Kentucky's Green River Valley and the surrounding hills. Since becoming a
national park in 1941, the area has also been designated a World Heritage Site and an
international Biosphere Reserve.
