The Sourdough Creek is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Workings): Workings / Exploration = Probably some exploration by pan or rocker before WWI.
Comment (Geology): Geologic Description = Collier and others (1908, plate X) describe Sourdough Creek as possibly auriferous over a 4- to 5-mile length on the Teller A-4 and Nome D-4 quadrangles. Collier panned one gold color on Sourdough Creek in 1901 (Collier and others, 1908, p. 220). In part on the basis of its location near the coastal plain and the stream's low relief, it is inferred that placer gold deposits would be of river-bar type with local enrichment in point bars and in inner curves of meanders, probably in association with black or ruby sand. Sourdough Creek probably reworks coastal plain deposits over its lower course, but its headwaters are in uplands underlain by a pelitic schist assemblage (Sainsbury, Hummel and Hudson, 1972).
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a).
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Collier and others, 1908
Comment (Geology): Age = Holocene.
