The Crooked 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 = One prospect hole dug near mouth of Crevice Creek. Nature of other workings not defined.
Comment (Production): Production Notes = Production recorded for gulches that feed the part of Crooked Creek that lies within Iditarod quad.
Comment (Reference): Primary Reference = Miller and others, 1989, p. 75
Comment (Geology): Geologic Description = Gold-bearing bench gravel E of Crooked Creek is 20 ft (6 m) above present stream, 1 mi (1.6 km) wide, and 10-100 ft (3-30.5 m) deep to bedrock. Gold is reconcentrated along tributary streams flowing through benches. Only a few short, narrow paystreaks, alternating with low-grade or barren gravel, in streams. Only 1 mi (1.6 km) of placer deposit is in Sleetmute quad; the rest is in the Iditarod quadrangle.
Comment (Deposit): Other Comments = Most of Crooked Creek placer and its tributary streams are in Iditarod quadrangle. Stream gradient is less than 50 ft/mi (9.5 m/km).
Comment (Deposit): Model Name = Placer; modern stream, bench
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary/Quaternary
