|Location and accuracy||American Creek is a southeast-flowing tributary of the Iditarod River south of Mosquito Mountain. The coordinates are near the mouth of the creek in the SW1/4 section 5, T. 22 N., R. 52 W., of the Seward Meridian. The location is accurate.|
Geologic descriptionThe 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).
