World-famous hydrothermal alteration landscape south of Goldfield where late Miocene acid-sulfate systems painted the hills in bright clays, alunite, and iron oxides. USGS and NASA remote-sensing programs (AVIRIS, ASTER, aircraft scanners) use Cuprite as a calibration field site; visitors see the multicolored waste and country rock from public desert tracks near the historic Cuprite camp on the Ralston quad.
