The Summit Mountain 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 (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = Limited surface work reported in the summer of 1931 (Park, 1933).
Comment (Reference): Primary Reference = Park, 1933
Comment (Geology): Geologic Description = According to Park (1933), Late Cretaceous Valdez Group argillite and graywacke are intruded and distorted by an irregular masses of argillically altered quartz diorite. A thin auriferous quartz vein strikes N 30 W, and dips 60 W. Rich float (presumably, in gold) reported just below the outcrop.
Comment (Deposit): Other Comments = See also: Bahrenberg - ARDF number AN110.
Comment (Deposit): Model Name = Chugach-type low-sulfide Au-quartz veins (Bliss, 1992; model 36a.1)
Comment (Geology): Age = Tertiary or younger; veins cut both Late Cretaceous Valdez Group rocks and Teriary intrusive rocks.
