The Unnamed (southeast of upper Finger Glacier) is a iron and titanium 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 ilmenite-magnetite occurrence at Rossman's (1963, B 1121-F) location number 44 is within and about 1.4 miles from the southwest contact of the Crillon-LaPerouse layered mafic-ultramafic intrusion (Brew and others, 1978). Layering in the stock near this locality strikes northwest and dips moderately steeply to the northeast. ? At the locality, ilmenite and magnetite are concentrated in cumulus layers. Analysis of a heavy-mineral concentrate (Rossman, 1963, table 7) by semiquantitative spectrographic methods found X0.0+ percent iron and X.0 percent titanium. Heavy-mineral concentrates also contained 0.X percent each of copper, lead, and tin and 0.0X percent of cobalt and nickel. The concentrations of the trace metals are sufficiently low that they do not prove separate mineral phases for any of the trace metals.
Comment (Deposit): Model Name = Possibly Bushveld Fe-Ti-V (Cox and Singer, 1986; model 3). Ilmenite and magnetite enriched in cumulus layers of a synorogenic (Foley and others, 1997) layered mafic-ultramafic stock.
Comment (Commodity): Ore Material = unknown sulfide phases
Comment (Deposit): Other Comments = Chugach terrane. The site is in Glacier Bay National Park and Preserve.
Comment (Commodity): Ore Material = unknown sulfide phases
Comment (Geology): Age = Tertiary.
Comment (Reference): Primary Reference = Rossman, 1963 (B 1121-F)
Comment (Workings): Workings / Exploration = Surface outcrops only; no development.
Comment (Exploration): Status = Inactive
Comment (Reserve-Resource): Reserves = No reserves projected. Thickness and horizontal continuity information lacking.
