The Second Beach (near the mouth of Cripple River) 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 (Deposit): Model Name = Beach placer Au.
Comment (Geology): Geologic Description = A placer mine near the mouth of Cripple River was reported by Sainsbury and others (1972 [OFR 72-321]). The location is on the west side of Cripple River, about 1,500 feet inland from the mouth. It is inferred to be on a westward extension of Second Beach that was mined at many places on the coastal plain to the east. Second Beach deposits were originally marked by a moss-covered gravel escarpment about 35 feet above modern sea level. It contains quartz sand deposits with driftwood, fragments of walrus tusks, and marine shells (Collier and others, 1908; Moffitt, 1906, 1907). There was more garnet in Second Beach deposits than in those of Third Beach. Second Beach is commonly buried by a few feet of material that is commonly frozen. The raised beach deposit is essentially at the landward limit of the Pelukian marine transgression mapped by Bundtzen and others (1994). The amount of production is unknown at this site.
Comment (Geology): Age = Late Pleistocene.
Comment (Reference): Primary Reference = Sainsbury and others, 1972 (OFR 72-321)
Comment (Workings): Workings / Exploration = Some surface workings or dumps from drifting must be present.
Comment (Exploration): Status = Probably inactive
