The Aspen Mountain is a aluminum mine located in Sweetwater county, Wyoming at an elevation of 8,271 feet.
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.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comment (General): "Alunite-bearing claystone is exposed near the base of a bulldozer trench that is 40 feet long, 10 feet wide, and 30 feet deep. Exposures here indicate that the alunite claystone is approximately 12 feet thick and dips about two degrees south. Flame photometer analysis of two samples indicates 32.0% and 29.5% Al2O3 and 6.8% and 5.8% K2O respeictively. A similar white claystone, 6 feet thick was penetrated at a depth of 145 feet by a core hole drilled a mile southwest of the alunite trench, but it is not known if this bed is alunite-bearing or not."
