Alum Cave Bluff in the Great Smoky Mountains must be considered a classic locality, inasmuch as Dana's System (Palache et al., 1951; Dana, 1892) lists four unusual minerals (potash alum, epsomite, melanterite and apjohnite) from "Alum Cave." The locality was studied during the 1800's (Brown, 1884); however, the authors have found no record of any studies during this century, and a revisit for a modern investigation is therefore long overdue.
