Location: Eakin (1968, p. 8) reported that placer gold has been found on a small lake between the two arms of Lake Nerka. For this record, the map site is in the NW 1/4 of section 6, T 8 S, R 55 W, of the Seward Meridian. It is on a small lake on the northeast flank of the uplands between the two arms of Lake Nerka. It is arbitrarily chosen to represent the occurrence reported by Eakin. It is very approximately located, probably within miles. Cobb (1972 [MF 375]; 1976 [OF 76-606]) included this occurrence under the name 'Lake Nerka'.
Geology: Eakin (1968, p. 8) reported that placer gold has been found on a small lake between the two arms of Lake Nerka. Bedrock in the area is mostly graywacke and argillite (Mertie, 1938) that is probably correlative with Jurassic clastic sedimentary rocks like those in the southeast part of the Hagemeister Island quadrangle (Jk unit of Hoare and Coonrad, 1978; Decker and others, 1994, fig. 1). Cretaceous or Tertiary intrusive rocks may be locally present.
Age: Holocene.
