| Description: | Creag a' Chalamain, Lairig Ghru, 10 km. south-east of Aviemore, Inverness-shire. V-shaped dry rock-gully (overflow channel across watershed). Tabular weathering along parallel joints in granite. Pink biotite granite belonging to Main Phase of the Cairngorm pluton, with widely-spaced vertical joints and closely-spaced later horizontal joints formed by pressure relief during unroofing well seen on cliffs to left. Overflow channel at a high level probably formed when ice sheet covered land surface, and etched into rock as ice sheet decayed. |
