The prospect is in the Wrangell-St. Elias National Preserve.
Location: This prospect is on lower Dry Gulch at an elevation of approximately 3,800 feet. The prospect is near the center of the south boundary of section 18, T. 4 N., R. 19 E. of the Copper River Meridian. This is National Park Service locality WRST-54 (unpublished data) and the coordinates for this prospect were provided by the National Park Service.
Geology: An unpublished National Park Service map and accompanying database identify this as a placer gold prospect that was active as early as 1914. Most of the bedrock in Dry Gulch varies from clinopyroxene diorite to monzonite of the mid-Cretaceous, Chisana pluton (Richter, 1976). The site is near the northwest contact of this pluton with Cretaceous volcanic and volcaniclastic rocks, which in turn overlie Jurassic or Cretaceous siliciclastic rocks to the north (Richter and Jones, 1973; Richter, 1976).
Workings: Some placer prospecting probably took place along this creek.
Age: Quaternary.
Commodities (Major) - Au
Development Status: Undetermined.
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a)
