The Caribou 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 (Production): Production Notes = No production
Comment (Reference): Primary Reference = Martin and Katz, 1910
Comment (Reserve-Resource): Reserves = No reserves
Comment (Workings): Workings / Exploration = Unknown, probably only hand-methods used for placer mining operations.
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Deposit): Other Comments = Site is in Lake Clark National Park and Preserve.
Comment (Geology): Geologic Description = Martin and Katz (1910; 1912) report fine gold but no pay from the northeasterly tributary to Caribou Creek, from Caribou Creek, and from Koksetna River.? the dominant bedrock in the drainage area is a Jurassic to Cretaceous flysch sequence and Tertiary volcanics (Nelson and others, 1983; unit KJs and unit Tv) . Unit KJs is interbedded lithic graywacke, silty sandstone, black shale , and local conglomerate. Irregular quartz segregations and veinlets are locally present. Scattered stocks and locally abundant dikes of intermediate to felsic composition including quartz monzonite, diorite, and granite intrude these sedimentary rocks. Adjacent to some of the larger igneous bodies are narrow contact aureoles of pelitic hornfels. Unit Tv includes rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows. Potassium-argon ages for unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
Comment (Geology): Age = Quaternary.
