Location: Beaver Creek drains west into the South Fork of the Chena River. The creek is roughly 12 miles long and has several tributaries, including Pine Creek (BD032). The Alaska Division of Mining Kardex file system reports placer mining on Beaver Creek at the base of Emory Creek. The approximate center of mining activity on Beaver Creek is in SE1/4SW1/4 section 5, T. 2 S., R. 7 E., of the Fairbanks Meridian. There are references to additional placer mining along Beaver Creek, but it is unclear where. It is locality 8 of Cobb (1972; MF-388), who summarized relevant references under the name 'Beaver Creek'.
Geology: Weber and others (1978) described the bedrock in the drainage as primarily greenschist facies rocks with some marble, quartzite, and phyllite. Locally, there is an extensive cover of windblown silt and sand that ranges from 0.1 to 50 meters in thickness. In addition, much of the ground in the swampy lowlands of the Chena River and its tributaries is permanently frozen (Foster and others, 1979). Scarce cassiterite was reported in the placer concentrates (Joesting, 1942). Glover (1950) reported a range in gold fineness of 721 to 758 for Beaver Creek. Ellsworth and Davenport (1913) report that gold was first mined in significant amounts in the winter of 1911-12. Prospecting also occurred on nearby Pine Creek (BD032). The Alaska Division of Mining Kardex file system records active claims on Beaver Creek as recent as 1984. Ellsworth and Davenport (1913) reported that gold production was measured in dollars per foot. Total amounts of gold produced from Beaver Creek were not reported.
