|Location and accuracy||Dewey Creek is a 2.5-mile long, southwest-flowing stream whose mouth is on the north shore of Grantley Harbor, 6 miles northeast of Teller. This is locality 68 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Dewey Cr.'.|
Geologic descriptionBedrock in the Dewey Creek drainage is a chlorite and mica schist assemblage that is locally intruded by small greenstone bodies (Sainsbury, 1972); the age of this assemblage is uncertain but it is probably Paleozoic. Placer gold is reported to be present in this drainage but there are no known mining operations.
