The Hidden Creek is a tin 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 (Exploration): Status = Inactive.
Comment (Geology): Age = Tertiary; mineralization is interpreted to be linked to the Kahiltna pluton (Tmk), part of the McKinley Sequence, that has been determined to range from 52.3 to 56.2 m.y. in age by K/Ar method (Reed and Lanphere, 1972; Reed and Nelson, 1980).
Comment (Workings): Workings / Exploration = Reconnaissance mapping, stream silt and rock sampling by the U.S. Geological Survey (Reed and others, 1978; Reed and Nelson, 1980) have been done here. Cassiterite occurs in quartz- tourmaline-muscovite veins (Reed and others, 1978; Reed and Nelson, 1980).
Comment (Reference): Primary Reference = Reed and others, 1978
Comment (Deposit): Other Comments = This occurrence lies within Denali National Park and Preserve.
Comment (Geology): Geologic Description = In the headwater basin of Hidden Creek cassiterite occurs in quartz- tourmaline-muscovite veins that cut biotite granite of the early Tertiary Kahlilna pluton (Tmk) (Reed and others, 1978; Reed and Nelson, 1980).
Comment (Deposit): Model Name = Sn Veins (Cox and Singer, 1986; model 15b).
Comment (Geology): Age = Chron age is for McKinley Sequence.
