|Location and accuracy||This placer deposit is at an elevation of about 3,300 feet on upper Bryn Mawr Creek. It is in the NW1/4 of sec. 3, T. 20 S., R. 11 W., of the Fairbanks Meridian. The location is accurate to within 0.5 mile. This is locality 8 of Cobb (1978: OFR 78-1062).|
Geologic descriptionThe Bryn Mawr Creek placer prospect produced small amounts of gold in 1909 (Cobb, 1978; OFR 78-1062). The source of the gold is the Golden Zone lode deposit (HE043), just upstream from the placer.
