Slide 58 of 66
Notes:
This is a view of part of the famous badlands of South Dakota. As a result of downcutting of the main river, the rolling, vegetated surface that existed on top of weak Cenozoic shales has been eroded by a wave of dissection as a wall of badland slopes works its way headward through the landscape. A modern, vegetation-covered pediment is forming at the base of the badland slopes as they retreat headward.
