The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This prospect is on the west valley wall of the upper White River. It is at an elevation of about 4,900 feet in a small drainage 2,500 feet south of elevation 6337, in the southwest corner of section 5, T. 2 S., R. 20 E. of the Copper River Meridian. This is locality 155 of MacKevett (1976); the location is accurate to within about 1,000 feet.
Geology: At this prospect, thin malachite-, bornite-, and chalcocite-bearing veins occur along small faults cutting Triassic Nikolai Greenstone (Capps, 1916; MacKevett, 1976). Reticulating veins of calcite and malachite coat some fracture surfaces. Surface cuts to 18 feet long explored this deposit (Capps, 1916, p. 123). Copper mineralization is common in Nikolai Greenstone and is thought to have accompanied regional deformation and low-grade metamorphism in the Late Jurassic to Early Cretaceous (MacKevett and others, 1997).
