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 = Menzie and Foster (1979) reported that the creek was an active gold placer claim from 1970 to 1977.
Comment (Geology): Geologic Description = Colorado Creek flows into the Chena River. Weber and others (1978) described the bedrock in the drainage as primarily upper-greenschist to lower-amphibolite facies quartzite and schists, along with some marble, argillite and phyllite. At the headwaters of the Colorado Creek drainage there is a granodiorite to quartz monzonite pluton of Tertiary to Cretaceous age. Locally, there is an extensive cover of windblown silt and sand that ranges from 0.1 to 50 meters in thickness. Much of the ground in the swampy lowlands of the Chena River, including Colorado Creek, is permanently frozen (Foster and others, 1979). The Munzie Lode (BD027) is located in the headwaters of the Colorado Creek drainage. Menzie and Foster (1979) reported that the creek was an active gold placer claim from 1970 to 1977. The Alaska Division of Mining Kardex file system records active claims on Colorado Creek as recent as 1984.
