wash forming a sloping plain. On this the end of the glacier 
rests, except at the north edge, where it descends a rock terrace. 
There is a notable dropping down of the upper surface not far 
back from the end of the glacier, and this stretches well across 
Fic. 46. Portion of the front wall of South Point glacier near the center of 
valley, seen looking southwesterly. The upper portion is nearly pure ice, but shows 
the stratification well. The dark ice at the upper edge of the talus slope is the bowl- 
dery layer mentioned in the text. The material of the talus is chiefly derived from 
this. The blocks of ice on and at the foot of the talus slope are masses detached from 
the glacier. 
the valley, as seen in Fig. 45. It suggests that this rock terrace 
extends far out under the ice in the bottom of the valley. Owing 
to this or some other cause the glacier’s upper profile is less sym- 
metrical than those of the Bryant and Fan glaciers. 
The most interesting feature of the glacier is its frontal edge. 
The view shown in Fig. 45 partially illustrates its character. It 
was taken from the northeast, looking obliquely across the axis
