Wright and Wright (1937) report claim activity (copper) at or near this location. The site is in Glacier Bay National Park and Preserve.
Location: The site is near tidewater about 2.55 miles south of the mouth of Tidal Inlet. The location of the site is accurate wihtin abount 0.1 mile. It is location number 41 of MacKevett and others (1971) and location number 87 of Kimball and others (1978).
Geology: The site is mainly underlain by marble and argillite and graywacke of Silurian and Devonian age that are intruded by hornblende diorite of Cretaceous age (Brew and others, 1978). At the site, thin quartz veins in marble contain pyrite, pyrrhotite, and chalcopyrite. A representative sample collected by MacKevett and others (1971, p. 50) contained 1000 ppm copper and 300 ppm each of cobalt and nickel.
Workings: Representative surface sample of veins contained 1000 ppm copper, and 300 ppm each of cobalt and nickel (MacKevett and others, 1971). Trace of gold, no silver detected. Wright and Wright (1937) reported claims staked for copper at or near this locality.
Age: Probably Cretaceous.

Commodities (Major) - Cu; (Minor) - Co, Ni
Development Status: No
Deposit Model: Contact deposit in marble near quartz diorite. Sulfide veins in marble.
