|Location and accuracy||Moose Creek is a tributary of the lower Fortymile River located about three-quarters of a mile west of the Canadian border. The exact location of mining on Moose Creek is not reported; the mine coordinates are placed near the mouth of the creek, in section 28, T. 7 S., R. 34 E., of the Fairbanks Meridian. The location is accurate within 1 mile. Moose Creek is locality 37 of Burleigh and Lear (1994). There is another Moose Creek placer occurrence (EA105) in the Eagle A-3 quadrangle.|
Geologic descriptionBedrock along lower Moose Creek consists of Paleozoic amphibolite-facies biotite gneiss and amphibolite (Foster, 1976). Bedrock along upper Moose Creek (in the Yukon Territory) includes orthogneiss, graphitic quartzite and quartz-muscovite schist of the Nasina Series and quartz-muscovite schist of the Klondike Schist (Mortensen, 1988). Extensive terrace gravel deposits are present on both sides of the lower portion of the Fortymile River, including near the mouth of Moose Creek. These terraces are as high as several hundred feet above the Fortymile River (Foster and Keith, 1968). Placer mining took place on Moose Creek in 1990 (Swainbank and others, 1991).
