Acirque stairwayor sequence ofcirque stepsis a stepped succession of glacially eroded rock basins.[1]Their individual formation is that of acirque.

These steps are arranged one above and behind the other at different heights in the terrain and caused by the same morphodynamic 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.[2]

A well-known example is theZastler Lochbelow the summit of theFeldberg,the highest mountain of theBlack ForestinGermany.
