During the summer of 1905 the senior author and Sidney Paige were engaged in a study of the ore deposits and the general geology of Prince William Sound. This work was continued in 1908 for a few weeks by both the present authors, who in 1909 extended it to the southern part of Kenai Peninsula. In these three field seasons the whole shore line of Prince William Sound (except that of some of the islands) and of Kenai Peninsula from Portage Bay to Seldovia Bay Of Cook Inlet was examined. In the course of this work all the tidewater glaciers and many others near tidewater were seen and some notes, photographs, and maps were made of all the tidewater glaciers and of many Of the others. This work was hurriedly done and was secondary to the study of the bedrock geology and the ore deposits; nevertheless it is thought worth while to put on record the information thus Obtained regarding the glaciers, for it will afford a basis for future study of the fluctuations of these ice streams. This paper, then, is not expected to make many additions to the large amount of scientific material concerning the problems of glaciers and glaciation that is already available, but it is intended to supply some definite information regarding the present positions of the fronts of the glaciers and the more evident facts of their ﬂuctuations. Moreover, it is hoped that this publication may attract attention to some of the most magnificent American scenery that is now accessible to the tourist and nature lover. Except the Columbia Glacier, the glaciers of Port Wells, and possibly one or two others, the ice streams here considered had not been figured nor described before this study was undertaken.
