The Graham 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 (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Geology): Age = Quaternary. Cripple Creek, a headwater tributary of Graham Creek, drains a Cretaceous/Tertiary monzonitic intrusive body that is the probable source of gold in these creeks (Bundtzen and others, 1987).
Comment (Geology): Geologic Description = The rocks in the vicinity of Graham Creek consist of chert, argillite, and volcaniclastic rocks. A headwater tributary of Graham Creek, Cripple Creek, drains a monzonitic intrusion (Chapman and others, 1985). This Cretaceous/Tertiary monzonitic intrusion is the probable source of gold in these creeks (Bundtzen and others, 1987). Prospecting and development work were reported along Graham Creek in 1940 (Smith, 1942); the exact location of prospecting is unknown. Two headwater tributaries to Graham Creek, Bear Creek (OP003) and Cripple Creek (OP005), were both mined.
Comment (Workings): Workings / Exploration = Prospecting and development work were reported along Graham Creek in 1940 (Smith, 1942); the exact location of the work is unknown. Two headwater tributaries to Graham Creek, Bear Creek (OP003) and Cripple Creek (OP005) were both mined.
Comment (Reference): Primary Reference = Smith, 1942
