|Location and accuracy||Kowkow Creek is a south tibutary to Trail Creek, which flows west to Butte Creek in the Faro Creek drainage. The headwaters of Kowkow Creek are on the northwest flank of Island Mountain. This is locality 5 of Hoare and Cobb (1977) and of Cobb and Condon (1972).|
Geologic descriptionKowkow Creek is in the non-glaciated part of the Faro Creek drainage. Placer gold mining started there in 1913 and continued through most years to 1940 (Harrington, 1921; Hoare and Cobb, 1977). The pay is 8 to 15 inches of compacted fine gravel on a clay (with some gravel) false bedrock that is overlain by 3 to 4 feet of dark gravel and 1 to 3 feet of muck (Harrington, 1921, p. 227). The depth to bedrock is not known. Kowkow Creek is one of the principal producers in the Arolik River basin. It was estimated to have contributed a large part of the 1,500 ounces of gold recovered from operations in this basin up to 1919 (Harrington, 1921). Some platinum was recovered along with the gold (Hoare and Cobb, 1977). Nearby uplands are underlain by Paleozoic and Mesozoic sedimentary and volcanic rocks intruded by Jurassic mafic and ultramafic plutons (Hoare and Coonrad, 1978). Stream sediments from drainages in these uplands commonly contain anomalous amounts of nickel (Hessin and others, 1978 (OF 78-9-L).

|Production notes||Kowkow Creek was mined intermittently from 1913 to 1940. A large part of the 1,500 ounces of gold estimated to have been produced from operations in the Arolik River basin by 1919 came from this creek (Harrington, 1921, p. 221). Total production to date (2001) probably is subtantially more than this amount.|
