This occurrence is in Wrangell-St. Elias National Park.
Location: This occurrence is about one-half mile southwest of the pass at the head of Canyon Creek near the foot of two active glaciers. It is at an elevation of about 4,300 feet in the NE1/4 section 7, T. 7 S., R. 6 E., of the Copper River Meridian. This occurrence is probably located to within one-quarter mile. It is locality 81of Winkler and others (1981 [OFR 80-892-B]).
Geology: Diffuse, widespread iron-stained zones in mylonitic metavolcanic rocks of the Haley Creek terrane contain disseminated pyrite and possibly chalcopyrite and sphalerite (Winkler and others, 1981 [OFR 80-892-B]). 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 (Winkler and others, 1981 [OFR 80-892-A]).
Workings: Surface reconnaissance only.
Age: Not known; the protolith ages of metasedimentary and metaplutonic rocks in the Haley Creek terrane are not known, but much deformation and recrystallization probably occurred in the mid-Cretaceous or later (Winkler and others, 1981 [OFR 80-892-A]).
Alteration: Oxidation; diffuse iron-stained zones are present.

Commodities (Major) - Cu, Zn?
