|Location and accuracy||The French Gulch placer gold prospect is along French Gulch about 0.5 mile from its junction with Healy Creek. The map site is in sec. 17, T. 12 S., R. 6 W., of the Fairbanks Meridian. This is location 64 of Clark and Cobb (1972).|
Geologic descriptionFrench Gulch drains the Tertiary Nenana Gravel, which locally contains gold paleoplacers. The source of the placer gold in French Gulch probably results from reworking the Nenana Gravel.
