Fig. 9. Possible maximum lateral extent of the last Scottish ice sheet in the Minches, estimated from the gradient and altitude of the periglacial trimline that descends from south to north along the Trottemish Escarpment. These estimated ice margins assume continued northwards ice movement, and do not take into account possible deflection by ice moving north-west from Wester Ross.
