Some sastrugi had a shape like the head of a turtle, with overhanging front and back under which a moat had been cut by erosion - thus: profile moat plan After leaving the ridge of the present beach we counted eight more and higher but less well developed, essentially paral- el beaches. The ridge seems to be due to the shoving action of the ice foot. The inner beaches had been cut off and partly worn away toward the south by the scouring action of the summer streams coming from the glacier. The front of the narrow fault south of the moraine is much steeper than the northern part of this place.
