|Location and accuracy||The map site of this gold placer prspect is at the junction of Shotgun and Little Shotgun creeks, which are east-flowing tributaries of Ohio Creek. The placer workings on Shotgun creek are approcimately 4 miles upstream from Ohio Creek. The workings on Little Shotgun Creek extend for about 3 miles above its mouth. The map site is at the south boundary of sec. 35, T. 19 S., R. 10 W., of the Fairbanks Meridian. This is location 26 of Cobb (1978: OFR 78-1062), and location E-36 of Balen (1990: OFR 34-90).|
Geologic descriptionLower Shotgun and Little Shotgun creeks drain Upper Jurassic to Upper Triassic(?) crystal tuff, argillite, chert, graywacke, and limestone. The upper parts of the creeks drain Upper Devonian serpentinite, basalt, chert, and gabbro, in thrust contact with Lower Jurassic and Upper Triassic sandstone and siltstone (Wilson and others, 1998). Capps (1919) reports that placer gold is present, but mining has not been successful.
