It typically slopes(5-7°) down from the base of a steeper retreating desert cliff, or escarpment,but may continue to exist after the mountain has eroded away. It is caused by erosion. It develops when sheets of running water (laminar sheet flows) wash over it in intense rainfall events. It may be thinly covered with fluvial gravel that has washed over it from the foot of mountains produced by cliff retreat erosion. It is typically a concave surface gently sloping away from mountainous desert areas. Coalescence of pediments over a large area results in a pediplain.
