 At right angles to the glacial moraines in the middle, crevasses, large, canyon-sized cracks, are apparent in the grey-brown ice that can be seen along the sides of the glacier.These cracks are formed from the stress arising between ice along the valley walls (that is slower moving as the friction is greater) and the relatively fast moving ice at the glacier's center.On the southwestern side of the glacier terminus, calving of ice is visible.
