The Alder 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 = Alder Creek is a site of historic placer exploration with possible minor production.
Comment (Deposit): Other Comments = See also Webber Creek (CY037). This site lies within the Yukon-Charley Rivers National Preserve.
Comment (Geology): Geologic Description = There has been historic placer gold mining on Alder Creek, and the creek shows evidence of worked ground (Mertie, 1942). The headwaters and upper portion of Alder Creek are underlain by Cretaceous to Tertiary conglomerate and other sedimentary rocks, but the creek then crosses a high-angle normal fault, and its lower half is underlain by Paleozoic to Precambrian metamorphic rocks (Dover and Miyaoka, 1988). The gold-bearing gravels at other placer mines within the quadrangle appear to be derived from the Cretaceous to Tertiary sedimentary rocks, and this may be the case with Alder Creek. This interpretation seems especially likely since Webber Creek, which Alder Creek joins, does not contain much, if any, gold (Cobb, 1976 [OFR 76-632]).
Comment (Production): Production Notes = There has not been much, if any, placer gold produced from Alder Creek (Mertie, 1942).
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a).
Comment (Reference): Primary Reference = Mertie, 1942
Comment (Geology): Age = Quaternary.
Comment (Exploration): Status = Probably inactive
