Geology: Dominion Creek and its principal tributaries head on Mt. Plummer and Marvel Dome, where an Upper Cretaceous granitic stock is surrounded by hornfels in sedimentary rocks of the mid-Cretaceous Kuskokwim Group (Box and others, 1993). Placer gold has been found at various places along Dominion Creek. A small glacier occupied the headwater valley of Dominion Creek. The middle and lower part of the drainage contains outwash deposits that are incised by the present creek (Maddren, 1915, p. 337). Fine gold colors have been found at the mouth of the creek (Maddren, 1915).
Workings: Placer claims have been staked on at least the lower half of Dominion Creek and some exploration is assumed to have taken place.
