| Description: | Coire Creachainn, east side of Ben Cruachan, 5.6 km. west-north-west of Dalmally, Argyllshire. Corrie in the Ben Cruachan granite. The amphitheatre-like hollow has been formed by glacial erosion. The corrie would have started out as a small hollow that captured a persistent snowbank then by a process termed nivation (i.e. the disintegration by freeze-thaw of the adjacent material and the removal of the shattered debris by falling and meltwater), the surrounding slopes remain steep and are gradually cut back. The hollow soon grows large then eventually large enough to develop a small glacier. This in turn leads to greater erosion of the walls and on the departure of the glaciers leaves us with a corrie. Note the impression of a lip at the exit of the corrie, this is commonly either a rock lip or formed from an arcuate ridge of moraine. The more international name for a corrie is a cirque. |
