Description:	Near Samuel's Geo, south of Freswick Bay, Caithness. Cletts, or broad-topped stacks of horizontal sandstone, isolated from main cliff by the undermining action of the sea and collapse of masses between the main joints. Thinly-bedded flat-lying flaggy siltstones of the Mey Siltstone Formation (Caithness Flagstone Group, Middle Devonian) are cut by two sets of vertical joints with a spacing of 1-5 m. The principal joints have been exploited by the sea. Deep clefts, called geos, penetrating far inland, are formed. Where two geos intersect, a vertical-sided stack, called a clett, is left.
