An elevated view across the South Dakota Badlands, where erosion has cut soft sedimentary layers into sharp ridges, deep gullies, and flat-topped buttes. The formations run in bands of tan, ochre, and olive to a flat horizon under a blue sky with scattered clouds. No buildings or people appear in the scene. The caption calls the view "Erosion of the ages," and the landscape is the reason Badlands National Monument was set aside in 1939; it later became Badlands National Park.
