EXPLANATION OF PLATE V 
Upper Figure. — Hall Island 
The view is toward the north. The smooth upper slopes, carpeted 
by tundra vegetation, are contrasted with the shore cliff, which is bar¬ 
ren because rapidly eaten back by the beating of waves against its base. 
The shore cliffs expose the anatomy of the island. From a photograph 
by E. S. Curtis, 1899. See page 36. 
Lower Figure. — Plover Bay 
The view is toward the south, or down the bay. It shows the 
southern half of the east shore of the bay. The more distant part of 
the shore is exposed to the waves of Bering Sea, as shown by its cliff. 
The coarse rock waste from this cliff has been built into a curved spit, 
on which the party landed. The collection of boulders from this spit 
illustrates the constitution of the mainland in the region of the cliffs.
