The mineral resources of the Mount Wrangell district, Alaska
The Tenth Census, taken in 1880, gives the number of white inhabitants of the Territory of Alaska as 430. In the decade from 1880 to 1890 this number had increased to 4,298, and in the following decade, that between 1890 and 1900, a further increase to 30,493 is recorded. The Director of the Mint in his report for 1891 gives the value of the yield of the Territory in precious metals as $772,197. By 1900 these figures were increased to $8,265,772. These statistics of the growth in population and in mineral output of Alaska serve as an index to the general increase in the importance and· commercial value of the Territory as an integral part of the domain of the United States. The larger part of this growth began with the discovery, late in the autumn of 1896, of the placer deposits of Klondike River in Canadian Yukon territory. Soon after this discovery there was a great influx of prospectors, miners, and, business men to all parts of Alaska, but particularly to the regions tributary to the Yukon, and with this increase in population came a proportional increase in transportation facilities and business interests.
Reconnaissance from Fort Hamlin to Kotzebue Sound, Alaska, by way of Dall, Kanuti, Allen, and Kowak Rivers
The reconnaissance described in the following pages was carried out in pursuance of a plan which has been followed for some years by the United States Geological Survey in the topographic and geologic exploration of the little-known parts of Alaska and in the collection of such information as will be of value not only to the scientific world, but to the prospector, the miner, and the trader. Capital disappears and years are wasted by prospectors who push out beyond the shifting frontier and pursue their search for gold where gold is not to be expected, and lives are being continually lost because the location and character of trails, drainage ways, and mountain ranges and passes are unknown, or because the knowledge which a few possess is not in a form available for the use of others.
