The Upper Chitina Valley, Alaska

The completion of the topographic and geologic reconnaissance surveys of all the developed mining districts in the Copper River basin has justified the utilization of the available funds for the extension of work into adjacent areas. As a part of this plan, the survey of the upper Chitina Valley was untertaken in 1915, and the results of this survey are here presented. Though this report deals largely with the more purely scientific aspects of the geologic problems, the solving of them has a definite economic value. It has been proved that the copper-bearing rocks, which have yielded valuable deposits in the lower Chitina Valley, occur also in the upper valley. It is also shown that the formations from which the Nizina placers have derived their gold occur in this region. On the other hand, no mineral deposits of proved value have yet been exploited in the upper Chitina basin. It must be said, however, that comparatively little prospecting has been done in this field.
