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.

Comment (Location): ON THE SOUTH FORK OF THE SNOQUALMIE RIVER NEAR SNOQUALMIE PASS

Comment (Development): ECON.COM: SHIPPED 20 TONS OF ORE PRIOR TO 1901 (HUNTTING, 1956, P.127).

Comment (Deposit): THE CARMACK MINE OCCURS IN ROCKS OF THE SNOQUALMIE BATHOLITH, NORTHERN PHASE, WHICH CONSISTS OF GRANODIORITE AND TONALITE AND IS LIGHT COLORED, MEDIUM CRYSTALLINE, AND MOSTLY EQUIGRANULAR AND HAS HYPIDIOMORPHIC TEXTURE. THE ROCKS ARE COARSELY JOINTED AND CONTAIN BIOTITE AND HORNBLENDE AND LOCALLY CLINOPYROXENE. AGE OF THE NORTHERN PHASE IS ABOUT 25 M.Y. BASED ON INTERPRETATION OF NUMEROUS DISCORDANT K-AR AGES OF BOTH HORNBLENDE AND BIOTITE (TABOR AND OTHERS, 1982, P. 8). ; INFO.SRC : 1 PUB LIT
