INTRODUCTION 
had visited various parts of Popof and Unga islands, and 
spent a week on Alaska Peninsula in the vicinity of Chich¬ 
agof Cove, Stepovak Bay. After a brief landing on the 
northwest coast of Kadiak Island, we reached Kadiak 
village on the morning of July 20, and the following day 
made an excursion by launch to Long Island. On the 
twenty-first of July we reached Homer, whence the main 
party made an excursion up Cook Inlet, while Dali, Gil¬ 
bert, and Palache visited Halibut Cove and Grewingk 
Glacier. On the twenty-third we touched at Yakutat, on 
the twenty-fifth at Juneau. Our last halt (July 26-27) 
was made at Cape Fox, near the southern boundary of 
Alaska, and we reached Seattle early on the morning of 
the thirtieth. 
Results . — The geologic field work of the Expedition 
may properly be characterized as a reconnaissance; and 
in this respect it resembles the greater part of the work 
which had previously been accomplished in the same 
region. While it was in progress there was much active 
exploration in the interior of the Territory, chiefly by 
members of the United States Geological Survey, and that 
work has continued in later years. The Geological Survey 
has also done a certain amount of systematic surveying, so 
that a beginning has been made in the definite mapping 
of Alaska geology. The area of the Territory is so vast 
and the workers are so few, that for many years broad 
generalizations can be reached only by the patching to¬ 
gether of widely scattered items of local information; 
and to the body of this local information the work of the 
Expedition makes a number of contributions. 
The results in glacial geology have already been pub¬ 
lished, partly by Muir, in volume 1, partly by Gilbert, in 
volume in. Muir’s paper is a general statement of the ex¬ 
tent and distribution of Alaska glaciers, brought down to 
date by the inclusion of the observations of the Expedi-
