|Location and accuracy||Bryan Creek is a northeast flowing drainage with some headwater tributaries on the northeast flank of the Kougarok Mountain upland. This location is at the confluence of Bryan Creek and its southeast tributary, Dick Creek. This confluence is at an elevation of about 275 feet on the eastern border of the Teller D-1 quadrangle. This is locality 65 of Cobb and Sainsbury (1972) and relevant references were summarized by Cobb (1975) under the name 'Bryan Cr.' and 'Dick Cr.'.|
Geologic descriptionDick Creek is a north-flowing tributary to Bryan Creek that has been placer mined for its gold content. Bryan Creek, the only placer mine in the Serpentine district, is almost all in the Bendeleben quadrangle. Only a small part of this mine, at the confluence of Dick Creek and Bryan Creek, may be in the Teller quadrangle. A dredge may have worked on the creek early on but most of the mining has been by dozer and sluice methods. Cassiterite and scheelite are reported from concentrates.
