Geographic wonders : wind cave and jewel cave. The other national treasures of the Black Hills, South Dakota

Auteur :
MITCHELL, M.

Description :
Although overshadowed by Mt. Rushmore National Memorial, which has become the place image of the Black Hills, Wind Cave National Park and Jewel Cave National Monument comprise two important national treasures set within the regional milieu of the Black Hills. These caves serve as prime examples of how very weak geomorphic processes associated with solution weathering can become dominant and render a vast and complicated subterranean landscape in an environment insulated completely from sunlight, rain, wind erosion, freezing/thawing, flowing water and bioturbation. Indeed, other than a few colonies of bats near the cave entrances, both caves are essentially devoid of life. - (IfL)
