| Sheer granite peaks and deep cirques are drained by clear, cold streams. |
| Where cirques form one behind the other, a cirque stairway results as at the Zastler Loch in the Black Forest. |
| Smaller lakes known as tarns occupy glacial cirques at higher elevations. |
| When three or more cirques erode toward one another, a pyramidal peak is created. |
| The erratic boulders, till, drumlins, eskers, fjords, kettle lakes, moraines, cirques, horns, etc. |
| Only a few lichens and mosses colonize the rocky walls of cirques and nunataks. |
