smaller islands, all mountainous. Traversing the straits, 
we found familiar signs of ice work: on Raspberry Island 
a straight wall with hanging valleys; on the Kadiak side 
a general rounding of all summits up to the clouds, which 
hung at about 2,000 or 2,500 feet. Here, too, the water 
is bordered in places by a lowland or terrace (fig. 85), 
carved, for the most part, from vertical slates. In detail 
the lowland is uneven, and it is locally broken into islands, 
but its general plane is easily traced and, as already noted 
by Dali, 1 inclines from east to west. The height ranges 
from about 100 feet to sea-level. 
At the extreme east lies Chiniak Bay, a broad opening, 
invaded on one side by mountain promontories, and partly

sheltered from the ocean by a group of low islands. Close 
to the islands is the village of Kadiak. The general trend 
of promontories and islands is northeast-southwest. The 
islands are shredded remnants of a plain carved from ver¬ 
tical slates, probably a base-level plain contemporaneous 
with the terraces along the straits (fig. 86). Their uneven 
surfaces include rounded hills about 100 feet high, but the 
plane of the original peneplain must pass above these. 
All surfaces about the bay are glaciated. The island 
topography is moutonnee, with a large pattern, individual 
bosses being sometimes half a mile or more in length. A 
few patches of glacial polish and striae were found, though 
such records have been generally obliterated by weather-
