Equiplain

 

a denudation surface occurring as a result of cirque denudation. It forms with the development of cirques on both slopes of an elevation. The walls of the cirques retreat toward one another, then connect, forming a sharp, crested divide. Finally they disintegrate completely and the bottoms of the cirques join. The term “equiplain” is sometimes used for planation surfaces of permafrost-solifluction origin.
