| Description: | Arkle (from the north-east), Sutherland. Characteristic weathering of imbricated quartzites forming screes; glaciated floors of corries (see photo C00003 half-plate). The quartzites forming the upper part of the mountain are cut by many small thrust planes, forming the imbricate zone. This thrusting has left them more vulnerable than the intact quartzites beneath to weathering, leading to the formation of extensive screes. Glacial erosion has produced a classic corrie with an arcuate, frost-shattered ridge and an ice-scoured floor. Note ice-polished bedding- or thrust planes in foreground. |
