4 . Mammoth Cave National Park, in the state of Kentucky, is a unique and historical natural wonder. It has the world’s longest cave system. There may be another 600 miles of cave passageways that have yet to be explored. In addition, more than 200 caves that are disconnected from the larger system can be found in the park.

The underground caves were created naturally by the process of limestone (石灰岩) erosion. Rain and rivers slowly dissolve (溶解) and shape soft limestone. The system is still being shaped today. Not only are they an amazing destination to visit, but the system also provides drinking water for about 40% of the US population.

The caves’ first explorers were Native Americans, who mined (采矿) the upper levels of Mammoth Cave. Later, the sites were left in great shape and began to draw public interest.

Mammoth Cave was made into a national park thanks to strong support. Back in the 1920s, the Southern Appalachian National Park Commission was set up in 1925. After years of work, as well as building roads and public facilities, the park was completed on July 1, 1941.

The park now receives around 2 million visitors a year, with about a quarter taking a tour of the caves—everything from a cultural tour to the more adventurous tours on offer. The cave supports more than 130 wildlife species (物种). The park is also much more than just a cave; the forest around has a diverse (多种多样的) range of species.
