The Colorado 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 = Placer prospecting on Colorado Creek took place before and during 1909 (Maddren, 1910). In 1934, Mertie (1937) panned gold at this site. There is no record of any further prospecting or mining.
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = The area of Colorado Creek is underlain mainly by pelitic schist, phyllite, slate, sheared chert, quartzite, and some areas of recrystallized limestone (Mertie, 1937; Cass, 1959; Patton and Moll-Stalcup, 2000). Colorado Creek drains the granite or granodiorite Khotol pluton (Cass, 1959; Patton and Moll-Stalcup, 2000). That pluton has been dated by K-Ar and Ar/Ar techniques at 108-112 Ma (Flanigan, 1998). Placer prospecting on Colorado Creek took place before and during 1909 (Maddren, 1910). In 1934, Mertie (1937) panned gold at this site. There is no record of any further prospecting or mining.
Comment (Deposit): Model Name = Placer gold (Cox and Singer, 1986; model 39a)
Comment (Reference): Primary Reference = Mertie, 1937
Comment (Geology): Age = Quaternary.
