Location: McGeary Creek is a large, south tributary to the upper Nushagak River. The location is arbitrarily chosen on upper McGeary Creek. The map site is in the NW1/4 of section 29, T 3 N, R 42 W, of the Seward Meridan. It is very approximately located, perhaps within as much as 10 miles. Cobb (1972 [MF 384]; 1976 [OF 76-606]) included information about this occurrence under the name 'Pulchatnachakcharak R.' an early name for McGeary Creek.
Geology: Mertie (1938, p. 91) reported that colors of gold have been found on McGeary Creek. This record represents that occurrence, at an arbitrarily chosen site along upper McGeary Creek. Bedrock in this drainage is probably mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group, perhaps locally intruded by felsic igneous rocks (Decker and others, 1994).
Age: Quaternary.
Commodities (Major) - Au
Development Status: None
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a)
