Black Rock Desert belongs on the list because the collecting context is an enormous BLM-managed volcanic and basin landscape rather than a single small pit. Local rockhounding guidance for Black Rock-High Rock country highlights minerals, common fossils, and petrified wood rules, while BLM documents the area's national conservation status and broad public-land recreation framework. Reported finds include opalized wood, petrified wood, agate, fire opal, geode, and more. Below: coordinates, access notes, nearby spots, and trip-planning links.
