This occurrence is in Wrangell-St. Elias National Park.
Location: This occurrence is on the north side of the ridge between Summit Lake and an unnamed north tributary to Bridge Creek at an elevation of about 5,000 feet. It is in SW1/4 section 21, T. 6 S., R. 7 E., of the Copper River Meridian. This occurrence is probably located to within one-half mile. It is locality 106B of Winkler and others (1981 [OFR 80-892-B]).
Geology: Winkler and others (1981 [OFR 80-892-B]) reported that copper and nickel sulfides are disseminated in mafic rocks of the Haley Creek terrane (Winkler and others, 1981 [OFR 80-892-A]). The polydeformed Haley Creek terrane consists of metasedimentary rocks, including marble and metaplutonic rocks that range from peridotite to trondjhemite (Winkler and others, 1981 [OFR 80-892-A]). The protolith ages are not known, but much deformation and recrystallization of the Haley Creek terrane probably occurred in the mid-Cretaceous or later.
Workings: Surface reconnaissance only.
