Badlands. Water-eroded "badlands" landscape,with numerous rugged hillocks that look like miniature mountains. Badlands terrain is produced by differ- ential erosion of horizontal beds of soft,sedimentary rock,such as sandy clay,that are un- protected by vegetation and subjected to occasion- al deluges of rain. Deep interlocking ravines develop,and the rocky slopes become heavily scored by drainage channels. Badlands are found in the semi-arid interior of North America and in North Africa. The name comes from the French explorers who described the area as mauvaise terres a traverser (bad lands to cross). This photograph was taken in Alberta,Canada | |
