Geology: An unpublished National Park Service map and accompanying database identify this locality as a copper vein prospect. Bedrock in the area is Triassic Nikolai Greenstone (MacKevett, 1974). 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).
