Location and accuracy | Reed and Elliott (1970, S-30, p.21) collected a float sample with visible base metal sulfides from a tributary to Upper Crystal Creek, near the western boundary of the Tyonek Quadrangle at about the center of the north side of sec. 25, T. 17 N., R. 21 W. (Cobb, 1972, MF 385, locality 3 and U.S. Bureau of Mines, 1998, MAS # 0020840003). Location is approximate to within a one mile radius. |
Geologic descriptionBoulder of altered, sheared, fine-grained igneous rock contains 2 percent disseminated pyrite, 1 to 2 percent galena, and traces of sphalerite and arsenopyrite (Reed and Elliott, 1970, S-30, p. 21). | |
