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.

Comments
Comment (Reserve-Resource): Estimated to have 1,500 tons of mirabilite, Na2SO4.10H2O, on the surface and 100,000 tons in the black mud, and 25,000 tons of epsomite, MgSO4.7H2O, on the surface and 150,000 tons in the black muds.
Comment (Identification): Probably should be called Soda Lake as that is the name on the topo map (Pine Tree Ridge 1:24,000). Unable to determine why this is called Brooklyn Lake. Lake described in WGS Bull. 50 says lake is 116.4 acres.
Comment (Reserve-Resource): EST 1500 TONS ON SURFACE&100,000 TONS IN MUD OF MIRABILITE A EST 25000 TONS ON SURFACE & 150000 TONS IN MUD OF EPSOMITE A
Comment (Deposit): "The surface has a salt crust from zero to 6 in. thick, and a layer of black mud from zero to 6 ft. thick contains salt." This is NOT NaCl although one sample contains 5.28% NaCl. NaCL should be considered a trace or impurity. Therefore, AB Wilson changed this record from NaCl as the primary commodity to Mg-compounds (Epsomite), and Na_Sulfate (Mirabilite).
