|Location and accuracy||Fish Creek is a small south tributary of the Middle Fork of the Fortymile River. The location of placer gold prospecting on Fish Creek is not reported; the coordinates are about 3 miles upstream of the mouth of the creek, in section 27, T. 6 S., R. 25 E., of the Fairbanks Meridian. Fish Creek is locality 26 of Burleigh and Lear (1994).|
Geologic descriptionThe rocks along Fish Creek consist of Paleozoic quartz-mica schist, greenschist, biotite schist, quartzite, and marble that have been intruded by Mesozoic hornblende granodiorite and Tertiary felsic igneous rocks (Foster, 1976). Prospecting occurred on Fish Creek in 1912 (Ellsworth and Davenport, 1913). Texas Creek (see EA061) is a tributary of Fish Creek that was prospected for placer gold.
