The Ridge 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 (Reference): Primary Reference = Hill, 1933
Comment (Workings): Workings / Exploration = Two shafts, 15 feet deep, were sunk on a 14-inch-thick, gold-bearing quartz vein. When visited in 1931, these shafts were flooded (Hill, 1933, p. 153).
Comment (Deposit): Model Name = Schist-hosted gold-quartz vein
Comment (Geology): Geologic Description = Two shafts were sunk to a depth of about 15 feet on a 14-inch-thick, gold-bearing quartz vein that strikes N. 50 E. and dips south (Hill, 1933, p. 153). Grab samples of the ore assayed $15.96 in gold per ton (0.77 ounce of gold per ton) (Hill, 1933, p. 153).
Comment (Exploration): Status = Inactive
