This occurrence is in Katmai National Monument.
Location: This occurrence is at the head of Windy Creek on the western flank of the Buttress Range. It is at an elevation of about 1,750 feet in the NW1/4 sec. 27, T. 22 S., R. 37 W., of the Seward Meridian. The location is accurate within one-quarter mile.
Geology: Church, Riehle, and Goldfarb (1993) collected rocks here that contain 150 parts per million (ppm) or more copper, 200 ppm or more lead, and 1,500 ppm or more zinc. The samples were collected in talus below a large breccia body exposed in a cliff wall. The breccia body contains clasts of Upper Jurassic Naknek (?) Formation sedimentary rock in a matrix of pyrite. They estimated that the breccia crops out over an area at 33 by 100 feet. in size.
Workings: Apparently only geochemical sampling by government geologists (Church, Riehle, and Goldfarb, 1993).
Age: Late Jurassic (?) or younger; the breccia body contains clasts that are probably from the Naknek Formation.
Commodities (Major) - Cu, Pb, Zn
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
