Site is located within Kodiak National Wildlife Refuge.
Location: This site is located 5.1 miles north of Anvil Mountain in sec. 32, T. 32 S., R. 33 W., of the Seward Meridian (Foley and Barker, 1985, figure 25, locality 49; Foley and others, 1989, locality 32). Site is accurate to within several hundred feet.
Geology: At this chromite occurrence, one of several in the Halibut Bay ultramafic complex, massive chromite segregations occur in dunite rubblecrop near a small shear zone. Because of lack of exposure no other data are available. The Halibut Bay ultramafic complex, consisting mostly of dunite, gabbro, pyroxenite, and periodite, occurs within sedimentary units of the Uyak formation of Cretaceous age.
Alteration: The ultramafic country rock is serpentinized?
Commodities (Major) - Cr
