ALASKA GLACIERS 
row bays may properly be designated fiords, although 
less strongly characterized than those of southern Alaska. 
Opportunities for personal observation included near 
views of the northern coast, a brief landing near the west¬ 
ern extremity, and a longer stay near the eastern extremity, 
with Kadiak Harbor as a base of operations. 
Our landing at the west was on a part of the coast fa¬ 
cing Shelikof Strait, west of Sturgeon River. The view 
was limited by a fog, but I was able to recognize two 
narrow U-troughs with simple contours. The ridge be¬ 
tween them, composed of granite rock, was seen to have 
a narrow, straight crest; and a parallel ridge, less clearly 
revealed, appeared to be of the same character. The 
troughs were evidently shaped by glacial ice, and the nar¬ 
rowness of the intervening crest indicates that the chief 
work was done by valley glaciers, rather than by an over¬ 
riding ice-sheet. 
Thirty miles farther east we entered the mouth of Uyak 
Bay, a long inlet heading south of the middle of the island 
but opening northward. The mouth lies among hills or 
low mountains, whose thorough rounding indicates com¬ 
plete flooding by Pleistocene ice. Toward the interior I 
could see mountains, several thousand feet high, whose 
blunt summits told of ice-scoring, and beyond them loftier 
peaks with angular crests. The slopes bordering the bay 
descend steeply to the water, and there is no foreland, but 
the sweeping curves characteristic of the typical fiord are 
wanting. No accumulations of drift were seen. 
Steaming north from Uyak Bay and then eastward, we 
passed two large projections of the coast, one a peninsula 
(Ugat) and the other an island (Uganuk), and the extrem¬ 
ities of these were thought not to be glaciated. On the 
peninsula are hills with ragged summits, apparently crested 
by outcropping igneous dikes. 
Straits separate the north end of the island from three
