|Location and accuracy||The Keefers Bar placer gold occurrence is about one-half mile west of the junction of the south end of the Keefer Cutoff and the Nushagak River. It is on the west side of the Nushagak River about a mile below the mouth of the Scandinavian Slough in about the middle of the boundary between sections 2 and 3 of T. 15 S., R. 51 W., of the Seward Meridian. This occurrence is location 1 of Cobb (1972), Cobb (1977), and MacKevett and Holloway (1977); the location is accurate to within one-half mile.|
Geologic descriptionFlour gold can be panned from sandbars on Nushagak River (Mertie, 1938).
