Cirque: Starting location for mountain glaciers, leaving behind a bowl shaped indentation in the mountain side once the small glacier has melted.(add geology book citation already in the article) [1] Cirque stairway: a sequence of cirques; U-shaped, or trough, valley: U-shaped valleys are created by mountain glaciers.
A cirque stairway or sequence of cirque steps is a stepped succession of glacially eroded rock basins. [1] Their individual formation is that of a cirque . 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 ...
