Book excerpt: Excerpt from The Willow Creek District, Alaska The exploration of the Susitna Valley, a part of the United States Geological Survey's first year's plan of Alaska surveys, was made by George H. Eldridge and Robert Muldrow in Eldridge's report contained the first ofl'icial confirmation of the occurrence of alluvial gold in the Susitna basin. Meanwhile the prospectors had been at work and in 1897 discovered the Willow Creek placers. It was not until 1906 that the Geological Survey was able to extend its work in this field. Reconnaissance mapping was then carried over the entire Willow Creek basin and the salient features of its geology were determined. Gold-bearing quartz was found in this district during the same year and lode developments followed. This led to a second examination of the district by the Survey in 1910. The results of this second examination gave proof of the occurrence of valuable lodes, and plans were consequently made for a detailed survey. Because of urgent demands for work in other parts of the Territory, this detailed survey had to be deferred until 1913. It was then completed in one season, and the results are set forth in this volume. The Willow Creek gold district lies along the contact zone of a great series of granodiorite intrusives that form much of the Talkeetna Moun tains. As has been repeatedly pointed out, a large part of the gold deposits of Alaska occur in such contact zones. This is the condition in southeastern Alaska and in the Fairbanks, Chandalar, Iditarod.
