The bizarre landforms called badlands are, despite the uninviting name, a masterpiece of water and wind sculpture. They are near deserts of a special kind, where rain is infrequent, the bare rocks are poorly consolidated and relatively uniform in their resistance to erosion, and runoff water washes away large amounts of sediment. On average, the White River Badlands of South Dakota erode one inch per year. They are formidable redoubts of stark beauty where the delicate balance between creation and decay, that distinguishes so much geologic art, is manifested in improbable landscapes – near moonscapes – whose individual elements seem to defy gravity. Erosion is so rapid that the landforms can change perceptibly overnight as a result of a single thunderstorm.
