Location and accuracy These placer claims are on Slippery Creek about six miles north of the front of the Alaska Range. For this record, the site is approximately located on Slippery Creek, on the boundary between T. 18 S., and T. 19 S., R. 19 W., Fairbanks Meridian. Near this point, Slippery Creek is in the NW 1/4 of T. 19 S., and the SW 1/4 of T. 18 S. The location is number 63 of MacKevett and Holloway (1977); claims at this location were reported by the U. S. Bureau of Mines (1973). Another placer claim was reported by Heiner and Porter (1972, location 127) on Slippery Creek near the Greenback and Terminus lode claims (MM173).

Geologic setting

Geologic description

This placer gold prospect is on a broad, braided section of Slippery Creek about 6 miles north of the front of the Alaska Range and about 8 miles below a gold lode exposed on the Greenback, Terminus, Magnet, and Old Sourdough claims (MM173 and MM172). The gold presumably occurs as fine particles locally concentrated on river bars. In this type of occurrence, gold often accompanies heavy minerals such as garnet or magnetite and accumulates in red or black sands as ephemeral placers in the river bars.

Production and reserves

Workings or exploration Claims were reported on Slippery Creek by the U.S. Bureau of Mines (1973), several miles north of the front of the Alaska Range. Arley Taylor may also have held placer claims in 1970 on 'Slippery Bench' in Slippery Creek, near the Greenback and Terminus claims (MM173) (Heiner and Porter, 1972, Mt. McKinley quadrangle, location 127).
Indication of production Undetermined

Additional comments

The prospect is in Denali National Park and Preserve.
