|Location and accuracy||Bering Creek is a south tributary to Eagle Creek (TE101) in the west-central Teller A-3 quadrangle. This 1.5 mile long, north-flowing stream's confluence with Eagle Creek is at about 490 feet surface elevation. The location of placer mining operations was not mapped by Sainsbury and others (1969) but Cobb and Sainsbury (1972) show two locations on this creek, locality 79 which is on the main drainage at a surface elevation of about 550 feet (0.75 miles upstream of the mouth) and locality 78 which is at the mouth. The upstream location is considered approximate. Cobb (1975) summarized relevant references under the names 'Bering Cr.' and 'Eagle Cr.'.|
Geologic descriptionBedrock in the Bering Creek drainage is a metapelitic sequence that is locally cut by metamorphosed mafic intrusive bodies (Sainsbury, 1972). The age of this sequence is uncertain but it is probably Paleozoic. Coarse, bright, unworn placer gold was handmined from this creek in the early part of the century (1902 to 1908; Cobb, 1975) and hydraulic operations took place at the mouth of the creek in 1946 (White and others, 1953). The character of the placer deposit has not been described.
