Geologic setting

Geologic description

Bedrock 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).
