Location and accuracy Eureka Creek is a small north tributary of North Fork (Kougarok River). It is the first north tributary upstream from the mouth of North Fork on Kougarok river. The mouth of Eureka Creek is 500 feet east of the Nome-Taylor road and 2,000 feet northeast of the roads crossing of North Fork. Placer mine workings are shown by Sainsbury and others (1969) to start 3,500 feet upsteam from the mouth and extend for 1,500 feet to Camp Creek, a small west tributary to Eureka Creek. This is locality 34 of Cobb (1972; MF 417; 1975; OFR 75-429).

Geologic setting

Geologic description

Early reports (Collier and others, 1908) reported mining about one mile upstream from the mouth that recovered fine gold from alluvial gravel containing schist and vein quartz fragments. Placer mine workings are shown by Sainsbury and others (1969) to start 3,500 feet upstream from the mouth and extend for 1,500 feet to Camp Creek, a small west tributary to Eureka Creek. Much bedrock is covered by tundra in the area but the nearest exposures are Lower Paleozoic metasedimentary rocks (Sainsbury and others, 1969; Till and others, 1986).
