|Location and accuracy||Silverbow Creek flows south to its mouth on Norton Sound, 3.1 miles west of Bluff and 2.6 miles northeast of Topkok. This is locality 107 of Cobb (1972, MF 445; 1978, OF 78-181). The location of mining on this creek is not well known; the location could be within 1 mile or more.|
Geologic descriptionSome placer mining took place locally on this creek up to 1930 (Cobb, 1978, OF 78-181); the presence of gold was first reported in 1908 (Collier and others, 1908). The placer deposits are apparently less extensive and lower grade than those on Daniels Creek (ARDF SO006), 3.1 miles to the east. Bedrock of the area is primarily a polydeformed, metapelitic schist of possible Precambrian age (Sainsbury and others, 1972); Till and others (1986) identify the Silverbow Creek drainage as an area of extensive Quaternary cover.
