Pediments
April 2005
A pediment is a broad, gently sloping erosion surface or plain of low relief that is often found in arid and semi-arid regions at the base of a receding mountain front. The example shown is from the Palo Verde Ranch 15-minute topographic quadrangle, southwest of Tucson, Arizona. This is one of the best examples the writer has ever seen.
