The Valley of Tears 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 = Active
Comment (Workings): Workings / Exploration = Surface prospects were found near a cabin; there were visible claim lines. All samples collected by Kimball and others (1978) of alluvial material contained gold that could be concentrated by panning. The placer may be the same deposit reported by MacKevett and others (1971, p. 67) as the Dundas River placer. The placer deposit was covered with nine claims owned by the Jimmie Martin estate. Tentatively the Valley of Tears placer is regarded as the same deposit that was given an uncertain location on the 'Dundas River' in Mt. Fairweather B-2 quadrangle by MacKevett and others (1971) and by Cobb (1972).
Comment (Commodity): Ore Material = Native gold
Comment (Geology): Age = Holocene.
Comment (Reference): Primary Reference = Kimball and others, 1978
Comment (Reserve-Resource): Reserves = Very low-grade resource; mineable in local concentrations.
Comment (Deposit): Model Name = River bar-type placer formed by reworking of slightly auriferous Holocene outwash and alluvium.
Comment (Production): Production Notes = Small, but some production probable.
Comment (Geology): Geologic Description = The Valley of Tears placer is about 2 miles south of the contact between a large granitic body of Cretaceous age and carbonate-rich strata of Paleozoic age (Brew and others, 1978). The deposit appears to be a river bar placer that was formed by reworking of slightly auriferous outwash and alluvium derived from the granitic contact region exposed at Lake Seclusion.? the Bureau of Mines collected nine 3- to 7.5-pound samples at the site (Kimball and others, 1978, p. C363-4). The samples were panned at Juneau; all panned concentrates contained gold visible under a binocular microscope. Fire assays of the samples indicated a very small total gold content (about 1 cent per cubic yard, with gold valued at about $300 per ounce). Mining equipment was found at the site. Probably miners found and mined small, rich concentrations of lag-concentrated sand and gravel in river bar deposits.
Comment (Deposit): Other Comments = the site is in Glacier Bay National Park and Preserve.
