Harding Pegmatite Mine is a preserved lithium-beryllium-tantalum pegmatite where UNM still allows small personal collecting under posted rules. New Mexico Geological Society and USGS-derived records document lepidolite, spodumene, beryl, microlite, apatite, muscovite, quartz, and related rare-element pegmatite minerals, making it the state's clearest public window into a classic complex pegmatite. Reported finds include blue apatite, bityite, eucryptite, purple lepidolite, rose muscovite, and more. Below: coordinates, access notes, nearby spots, and trip-planning links.
