The Elephant 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 (Geology): Geologic Description = The trail development along Elephant Creek suggests that placer gold mining may have taken place at least locally along about 2 miles of its length upstream from Wilson Creek (RM002). The placer gold was discovered in 1914, and hydraulic mining was under way by 1916. The gold is in modern stream deposits and is accompanied by minor scheelite (Joesting, 1942). Bedrock in the Elephant Creek drainage is sedimentary and igneous rocks of the Gemuk Group that are locally intruded by Mesozoic or Tertiary granitic rocks (Hoare and Coonrad, 1959). The sedimentary rocks include chert, siltstone, sandstone, and conglomerate, and the intrusive rocks include biotite quartz monzonite, diorite, gabbro, hornblende porphyry, and felsic rocks (Bull and Schneider, 1997).
Comment (Reference): Primary Reference = Hoare and Cobb, 1977
Comment (Workings): Workings / Exploration = Underground mining methods were used before 1916; hydraulic methods were used from 1916 intermittently until at least 1940.
Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
Comment (Geology): Age = Quaternary.
