Geologic setting

Geologic description

Moffit (1905) reports that small amounts of bright gold have been found in gravels of American Creek, and Anderson (1947, p. 41) reports that cassiterite is also present. Mining activities have not been reported (Cobb, 1975, OFR 75-429). Most of the bedrock in the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986). However, the headwaters of American Creek includes Crossfox Butte which is underlain by Cretaceous granitic rocks (Till and others, 1986).
