Enchanting Landscapes Beneath the Parks

The National Park Service manages some of the world's most amazing places. This includes over 4,700 caves with at least four of these that extend for more than 135 miles and are so complex that the casual visitor would be lost among the hundreds of passages to choose from. This also includes karst, a type of landform where sinkholes, sinking streams, and springs are considered normal features and are indicative of the relationship found between the surface and the underground.
