Floyd Collins is perhaps the most famous person you've never heard of, but this young man's tragic death made him celebrated as the Greatest Cave Explorer Ever Known.

Collins was a Kentucky cave explorer in the early part of the 20th century, characterized by his lack of fear when exploring the most difficult cave passages, and few people could match his persistence and endurance. In the winter of 1925, Collins became trapped for more than two weeks in a cave located within the boundaries of what is now Mammoth Cave National Park. The story of Floyd Collins becoming trapped and ultimately dying alone in a cave held a powerful grip on the hearts and minds of people the world over. The resulting media coverage put Mammoth Cave on the map and helped usher the actual designation of Mammoth Cave as a national park. His explorations laid the foundation for others to later discover the truth of Mammoth Cave, the longest cave in the world.

Take a visual, historic tour of the world's longest known cave system with caving enthusiasts Bob and Judi Thompson.

Mammoth Cave National Park is made up of more than 53,000 acres. The region is characterized by what geologists call karst topography, a landscape dotted with sinkholes and caves. One of America's first tourist attractions, the cave was opened to the public in 1816, and was preceded in popularity only by Niagara Falls. The park was established as a national park on July 1, 1941, a World Heritage Site on October 27, 1981, and an international Biosphere Reserve on September 26, 1990.

Bringing to life more than a century's worth of fascinating stories and history of Cumberland Gap National Historical Park.

Best known for its pivotal role in opening up the western frontier and its association with explorers and pioneers, the legendary Cumberland Gap has long been celebrated in music and literature. To better preserve that history, Cumberland Gap National Historical Park was authorized in 1940 and now covers more than 24,000 acres in Kentucky, Virginia, and Tennessee. Daniel Boone is remembered here, as well the Native Americans who used the path through the mountains for trade and warfare, the Civil War soldiers who took turns guarding this strategic portal, the geologists and industrialists who saw the potential for development, the businessmen who built one of the nation's first roads for automobile travel and the displaced residents who gave up their homes for the park. The dream of a few dedicated individuals to one day restore the historic Wilderness Road through the Cumberland Gap came true in 2002 after decades of planning, and visitors can once again walk in the footsteps of the pioneers.
