The Moran Creek (Gulch) 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 (Geology): Age = Quaternary; this part of the Solomon River is at low enough elevations to have been affected by Quaternary sea level fluctuations and the gold probably went through several cycles of erosion and redeposition.
Comment (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a); possibly reworked alluvial and coastal plain deposits by more than one cycle of deposition.
Comment (Workings): Workings / Exploration = Small scale open cut placer workings are present on this creek.
Comment (Reference): Primary Reference = Smith, 1909
Comment (Geology): Geologic Description = Early placer mining on Moran Creek (1908) was on gravel benches of the Solomon River (Smith, 1909) and the deposits may be reworked alluvial deposits. This part of the Solomon River is at low enough elevations to have been affected by Quaternary sea level fluctuations and the gold probably went through several cycles of erosion and redeposition. The gravels that were mined included at least some that were 3- to 4-feet thick on decomposed schist bedrock. Bedrock here is part of a lower Paleozoic metasedimentary assemblage that includes a distinctive black, very fine-grained, graphitic schist (Sainsbury and others, 1972, OFR 511; Till and others, 1986).
Comment (Exploration): Status = Active?
