Report on Progress of Investigations of Mineral Resources of Alaska in 1904 (open access)

Report on Progress of Investigations of Mineral Resources of Alaska in 1904

From letter of transmittal: The report contains fourteen papers, prepared by ten members of the geologic corps, who have been engaged in Alaskan investigations during the last year. In this report an attempt has been made to summarize the economic results of last season's field work. Geologic matter has been entirely excluded, except where it has a direct bearing on the subjects under discussion. While such a report can have no permanent value, other than as a record of mining conditions during the year, it is believed that its prompt publication will help the mining industry of Alaska.

Preliminary Report on the Ketchikan Mining District, Alaska, with an Introductory Sketch of the Geology of Southeastern Alaska

From introduction: Since 1898 the United States Geological Survey has been carrying on a systematic investigation of the mineral resources of Alaska.As the northern mining districts of southeastern Alaska had already been the subject of an investigation by Dr. Becker in 1895,a and as the Ketchikan district was being rapidly developed, it was decided to spend the greater part of the short season in the Ketchikan district and in the fall to make a more hasty reconnaissance of the northern belt, in order to obtain a general familiarity with the region and, if possible, to establish some correlations. This plan was carried out, and the results of the work are embodied in the following report.
