The Ketchem Dome Area 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.

Comment (Exploration): Status = Active
Comment (Geology): Geologic Description = The creeks around Ketchem Dome drain a variety of rock types. To the north and northeast of Ketchem Dome, Ketchem and Holdem Creeks drain an area underlain by Tertiary granite. To the south, the Bottom Dollar Creek drainage is underlain by both Cretaceous granite and quartz-muscovite schist - the Lower Schist unit desribed by Wiltse and others (1995). Deadwood Creek drainage to the northwest is underlain both by Tertiary granite and the quartz-muscovite Lower Schist.? Gold is found in the gravel close to bedrock and in cracks in the bedrock. Placer gold has been mined on several creeks within this area that have been described separately (see Workings and Exploration).
