Here the west facing flank of Foinne Bheinn (Foinaven) is seen along its entire length. The pale almost white outcrop of the Cambrian Quartzite Group comprising the basal Quartzite and the Pipe Rock rises from south to north capping all of the summits on the ridge except for the northern summit where the Lewisian gneiss reaches its highest elevation on Ceann Garbh.
The line of the unconformity between the two rock Groups is clear on the mountainside, only breached where white quartzite screes extend over the Lewisian rocks.
Whilst on Ganu Mor the false bedded Quarzites rests largely undisturbed, in the south the whole of the mountain slope, the western edge of the Plat Reidh is underlain by the Cambrian strata, but here they are disturbed by thrust faults and stacked up by reverse faults increasing their thickness.
