Book excerpt: Excerpt from Preliminary Report on the Ketchikan Mining District, Alaska: With an Introductory Sketch of the Geology of Southeastern Alaska Since 1898 the United States Geological Survey has been carrying on a systematic investigation Of the mineral resources Of Alaska. On account of the rapid development Of the placer fields of Seward Peninsula and the interior, the money appropriated for Alaskan surveys during the first three years was chiefly spent in explorations and reconnaissances of these fields, and the mining districts Of southeastern Alaska were not given the attention which their importance demanded. For this reason a geologic reconnaissance Of southeastern Alaska was undertaken in the season Of 1901, and the writer was placed in charge of the work. His field orders authorized him to examine such portions of southeastern Alaska as time would permit. It was originally planned to make a general reconnaissance Of all the mining districts of that region, but it was found that this was too great an under taking for one field season, especially as the writer was detained in Washington until late in June, and the limited funds available necessitated a curtailment Of expenses by shortening the field season. As the northern mining districts Of south eastern Alaska had already been the subject Of an investigation by Dr. Becker in 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. The field work was much hampered by the lack Of topographic maps, and the resources Of the party were insufficient to permit Of carrying on systematic topographic work. Fortunately, however, the coast line proper had been charted with fair accuracy by the reconnaissance work Of the Coast and Geodetic Survey.
