Virgin Valley — Rockhounding in Humboldt County, Nevada

Virgin Valley is the United States' classic black-opal district, with USGS and Mindat both placing the opal field near the Oregon line in the Sheldon refuge country. Its strongest geologic feature is opal replacing mid-Miocene wood, including petrified wood and rare plant material, although most precious-opal ground is claimed and any collecting has to respect mining and refuge restrictions. Reported finds include agate, chalcedony, chert, flint, jasper, and more. Below: coordinates, access notes, nearby spots, and trip-planning links.
