The occurrence is in Denali National Park and Preserve.
Location: This occurrence is at an elevation of about 2200 feet on the northwest side of the ridge between Little Moose Creek and Little Caribou Creek. It is about 1 mile above the confluence of Myers Creek and Little Caribou Creek, in the SW1/4NE1/4 section 14, T. 13 S., R. 15 W., Fairbanks Meridian. The occurrence corresponds to number 90 of Hawley and Associates (1978) and 78 of Bundtzen (1981).
Geology: This occurrence consists of poorly exposed skarn in calcareous schist of the Birch Creek Schist. A fault, which appears to control the course of Little Caribou Creek, separates the Birch Creek Schist from Keevy Peak Formation west of the fault (Hawley and Associates, 1978, fig. 4.1-A(2)). Intrusive rocks are not known in this area. The skarn consists mainly of epidote, magnetite, pyrite, and small quantities of sphalerite and galena. Two samples contained 0.023 and 0.067 percent lead, 0.132 and 0.188 zinc, and a trace of silver in each (Bundtzen, 1981, number 78, table 10).
Workings: The occurrence was discovered during mapping (Hawley and Associates, 1978). There are no workings.
Age: The occurrence is of uncertain age. It may be Eocene (see record MM091).
Alteration: Metasomatic replacement of calcareous schist.

Commodities (Major) - Zn; (Minor) - Ag, Fe, Pb
