| Description: | Stob Choire Claurigh ('The White Corries'), 8.0 km. east-north-east of Ben Nevis, Inverness-shire. Frost-riven arete of Glencoe Quartzite (Dalradian Supergroup). Part of a panorama with C01835. When water fills the cracks of crevices and pores in a rock and then freezes, it expands by more than 9 per cent of its volume. This represents a bursting pressure of 150 kg. per square centimetre. The rocks are wedged apart and fragment and when a thaw sets in, become loose. This process has been going on for the thousands of years since the last glaciation with the result that mountainsides are covered in loose blocks. On the steeper slopes these fall to form talus or scree slopes. |
