These steps are arranged one above and behind the other at different heights in the terrain and caused by the same geomorphodynamic processes, albeit resulting in different landform shapes depending on the type of rock and the depositional circumstances involved. The lower step often lacks the steep headwalls typical of cirques.Leser, Hartmut, ed. (2005). ''Wörterbuch Allgemeine Geographie'', 13th ed., dtv, Munich, p. 915 (''Stufenkar''). .
