| Description: | Arkle seen from the west-south-west across Loch Stack, Sutherland. Lewisian gneiss in foothills and half-way up Arkle is overlain unconformably by Cambrian quartzite. Note stone cross on island in Loch Stack. Note absence of Torridonian strata between Lewisian and Cambrian and planar nature of unconformity. Lower part of Cambrian Eriboll Sandstone outcrop undisturbed. Above the Sole thrust, marked by a change in colour in the quartzites, the quartzite has been cut by many steeply-dipping minor thrusts with the same beds repeated many times (the imbricate zone). |
