Location and accuracy Harris Creek is the principal north tributary to the North Fork of Kougarok River. The mouth of Harris Creek is about 3.7 miles upstream from the Nome-Taylor road crossing of North Fork. Sainsbury and others (1969) show placer mine workings on the main channel of Harris Creek starting at the mouth and continuing upstream for 4.3 miles. This is locality 35 of Cobb (1972; MF 417; OFR 75-429).

Geologic setting

Geologic description

Gold was discovered in gravels of Harris Creek by 1900 and placer mining started here by 1901 (Collier, 1902; Collier and others, 1908). Sainsbury and others (1969) show placer mine workings on the main channel of Harris Creek starting at the mouth and continuing upstream for 4.3 miles. A dredge operated on at least parts of this drainage. The lower 2 miles of the stream channel crosses Paleozoic marble bedrock and the upper 2-plus miles crosses Lower Paleozoic metasedimentary rocks (Sainsbury and others, 1969; Till and others, 1986). Some auriferous bench gravels are reported along upper parts of the creek. The Harris Creek channel gravels are locally thin, 6 feet or less, and covered by up to 6 feet of muck. Gold was rough and concentrated on broken and fractured limestone (marble) bedrock. Garnet was present in some placer concentrates. This area has undergone at least two cycles of erosion and placer development. The garnet in placer concentrates was probably derived from headwater areas where schist is present.
