|Location and accuracy||This placer prospect is very approximately located in the headwaters of Bogus Creek. Bogus Creek flows northwest to the Kuskokwim River and the map site is arbitrarily located along the headwater drainage in the NE1/4 sec. 27, T. 13 N., R. 60 W., of the Seward Meridian. This is locality 15 of Hoare and Cobb (1972, 1977).|
Geologic descriptionPlacer gold colors have been found along upper Bogus Creek where it drains foothills to the Kuskokwim River lowlands (Maddren, 1915). In about 1904, a prospect shaft was sunk to a depth of about 50 feet in frozen gravel somewhere along this part of the creek. Bedrock in upper Bogus Creek includes volcanic rocks of the Whitefish Lake volcanic field and thermally metamorphosed Jurassic rocks along the west side of a large, mid-Cretaceous granitic pluton (Box and others, 1993).
