Relative position Snow Gulch is a small north tributary to Arolik River (GO036). The mouth of Snow Gulch is 2 miles upstream of the mouth of Faro Creek. Placer mining has taken place along the lower mile of Snow Gulch. The map site is at the approximate midpoint of the placer workings, in the N1/2 of section 30, T 7 S, R 71 W, of the Seward Meridian. It is locality 8 of Hoare and Cobb (1977) and of Cobb and Condon (1972).

Comments on the geologic information

  • Geologic Description = Placer gold mining occurred on Snow Gulch in 1913 or earlier and in 1938 to 1940 (Harrington, 1921; Hoare and Cobb, 1977); it may also have occurred at other times between 1913 and 1940. Open-cut placer tailings are present along about one mile of the creek upstream from its mouth. Information about the deposit is not available, other than that some platinum was recovered along with the gold. The creek was prospected for platinum in the 1960s by the Goodnews Bay Mining Company. A sample of platinum from Snow Gulch contained 76.32 percent Pt, 8.34 percent Ir, 8.34 percent Os, 5.05 percent Ru, 1.26 percent Rh, and 0.69 percent Pd (Mertie, 1969, table 38). Snow Gulch flows along a large, vertical, notheast-trending fault in Precambrian crystalline rocks (Hoare and Coonrad, 1978).
