|Location and accuracy||Dome Creek is the principal headwater tributary of Iron Creek (SO127). Dome Creek merges with Canyon Creek to form Iron Creek. Dome Creek is included in locality 33 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionThe entire 2.5 mile length of Dome Creek has been placer mined. The creek was worked by small-scale methods for several years after gold discovery about 1900 and a dredge worked a considerable amount of the creek in 1939 and 1940 (Sainsbury and others, 1972, OFR 512; Cobb, 1978, OF 78-181). Some very coarse gold has been recovered, at least one nugget was over 32 ounces, and heavy mineral concentrates contained magnetite, garnet, and ilmenite (Smith, 1909). Cinnabar is also reported to be present in Dome Creek (Sainsbury and others, 1972). Bedrock in the area is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
