Description: Ben Arkle, looking north from 1.2 km. north of Achfary, Sutherland. Mountains of Cambrian quartzite unconformable on Lewisian gneiss. Unlike many of the mountains further south, the Cambrian rocks are unconformable directly on the Lewisian, there is no intervening Torridonian. The unconformity represents a major stratigraphic break between much older Lewisian which underwent many periods of deformation and the Cambrian whose deposits were laid down on a remarkably flat marine platform. The plane of the unconformity is well seen below screes.
