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

Description: 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.
