Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Ruby is a remarkably intact early-20th-century mining camp in the Oro Blanco Mountains near the Mexican border. Schoolhouse, jail, homes, and mill ruins survive in dry oak-grassland country. Public access has been intermittent and fee- or tour-based through private caretakers—confirm current entry rules before driving the long dirt roads.
