|Location and accuracy||This gold placer prospect is on Wickersham Creek about 3 miles upstream from its junction with Butte Creek. The map site is at the midpoint of a mile-long interval of placer activity, in sec. 11, T. 21 S., R. 1 W., of the Fairbanks Meridian. This is location 69 of Clark and Cobb (1972); and location B-6 of Balen (1990: 34-90).|
Geologic descriptionWickersham Creek drains an area of Lower Tertiary granodiorite and granite that cuts Lower Cretaceous and Upper Jurassic deformed and metamorphosed flysch (Wilson and others, 1998). The placer gold was probably derived from the erosion of nearby lode deposits (HE171, HE172, and HE173).
