The Early History of Mammoth Cave, Kentucky Show Cave Wars & Floyd Collins

Kentucky’s cave country is rich in history. Learn how saltpeter was mined from Mammoth Cave during the war of 1812. View historic photos from the Kentucky Show Cave Wars where cave owners competed aggressively to get tourists to visit their caves. These “wars” culminated in the ill-fated cave rescue of Floyd Collins, a cave explorer and owner of Crystal Cave. Floyd’s story captivated the nation in 1925 and today he is memorialized as the “Greatest Cave Explorer Ever Known.”
