This occurrence is in Katmai National Monument.
Location: This occurrence is on the southeast flank of Mount Griggs at the head of Ikagluik Creek. The occurrence is at an elevation of about 1,600 feet in the SW1/4 sec. 22, T. 21 S., R. 35 W., of the Seward Meridian. The location is accurate within one-half mile.
Geology: This occurrence consists of small, galena-bearing quartz veins in a Tertiary hypabyssal stock. Nearby, float consists of large fragments of quartz with sphalerite and galena in vugs. The quartz veins probably also contain pyrite and chalcopyrite. The lack of abrasion on the galena crystals and the size of the fragments of float suggests their source is near the quartz veins (Church, Riehle, and Goldfarb, 1993).
Workings: Apparently none beyond sampling by government geologists.
Age: Tertiary or younger; the small galena-bearing quartz veins cut a Tertiary hypabyssal pluton.
Alteration: Nearby stocks show pervasive propylitic alteration at their margins.

Commodities (Major) - Au, Pb, Zn; (Minor) - Cu
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
