Geologic setting

Geologic description

The modern fluvial gravels near the mouth of American Creek are from 160 to 320 feet wide. The nonmagnetic fraction of a heavy mineral concentrate from a sample collected by the U.S. Geological Survey contained visible gold grains (Bennett and others, 1988). The sources of the placer gold may be the lode deposits in the drainage of American Creek (ID152 to ID154).
