|Location and accuracy||Macklin Creek is the northeast headwater tributary of Kougarok River. Macklin Creek joins with Washington Creek to become Kougarok River in the northcentral Bendeleben C-6 quadrangle. This location includes areas of placer mining on Macklin Creek that continues upstream across the Bendeleben C-6 and D-6 quadrangle boundary. Sainsbury and others (1969) show 8,500 feet of continuous placer workings along the main channel of Macklin Creek starting 4,500 feet upstream of the mouth. This is locality 26 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionPlacer gold deposits were first reported to be worked on Macklin Creek in 1901 (Collier, 1902). This first mining included pay streaks with pans worth $0.75 (0.04 ounces at $18 per ounce). Sainsbury and others (1969) show 8,500 feet of continuous placer workings along the main channel of Macklin Creek starting 4,500 feet upstream of its mouth. Macklin Creek has been extensively worked over this distance and has apparently been an important producer in the upper Kougarok River area. Bedrock in the area is part of a Lower Paleozoic metasedimentary assemblage (Till and others, 1986).
