Location: This occurrence is at an elevation of about 5,400 feet, about a mile north of Clearwater Creek. It is in the SE1/4SE1/4 section 27, T. 19 S., R. 4 E., Fairbanks Meridian. The occurrence corresponds to locality 10 in table 2 of Nokleberg and others (1991). The location is probably accurate within a quarter of a mile.
Geology: The rock at this occurrence is mica-garnet schist and amphibolite of the Maclaren Glacier metamorphic belt (Nokleberg and others, 1982, 1991). The area is traversed by a series of thrust faults, including the Meteor Fault. Metamorphism and thrusting are probably of Cretaceous age. The mineral occurrence is pyritic white-mica and garnet schist. A grab sample of the schist contained 1,000 parts per million zinc (Nokleberg and others, 1991, locality 10, table 2), probably contained in a discrete mineral such as sphalerite.
Workings: There are no workings at the site.
Age: Either the age of the protolith or synchronous with Cretaceous (?) metamorphism and thrusting.
