Harding Pegmatite Mine: Blue Apatite & Bityite Rockhounding in Taos County, New Mexico

Updated June 2026

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.

This spot sits on metasedimentary rocks, mapped as pelitic schist, muscovite schist, and quartzite that formed roughly 2500 to 1600 million years ago. Metamorphic terrain like this typically carries quartz veins and sweats, and weathered crystals tend to end up in the soils and streams below.

Mapped unit: metasedimentary rocks
Age: 2500–1600 Ma (Paleoproterozoic)
Rock types: pelitic schist, muscovite schist, and quartzite
Elevation: 7,410 ft
