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.

Description: The Golden Horn Batholith Was Intruded Into The Hozameen Fault, The Major Fault Bounding The Southwestern Side Of The Methow Basin. Radiometric Dating Suggests That Magmatic Crystallization Occured At Approximately 47 M.Y. K-Ar Biotite, Fission-Track Allanite, Rb-Sr Isochron Ages That Fall Between 38 And 42 M.Y. Probably Represent The Age Of Postcrystallization Hydrothermal Alteration (Stoffel And Mcgroder, 1990).
