Gr. Hexenkopf, East Tyrol: Rock crystals from north face cleft

The Großer Hexenkopf (3.313 m) is a summit in the Eichham group situated southeast of the Großvenediger in the national park Hohe Tauern. The specimen offered below stem from a big cleft in its north face, which can be reached most conveniently from Prägraten a. G. (Virgental) via Timmeltal and Kleinitzalpe. The cleft is situated in an altitude of nearly 3.300 m and can only be accessed by climbing exposed terrain. The cleft was found and worked already in 1980, i.e. before the national park legislation set a strict prohibition of mineral collecting for Osttirol (East Tyrol). The cleft paragenesis comprises rock crystals of good luster and clarity with turquois schist inclusions on selected rhombohedron faces, calcite, minor titanite and some copper mineralisation in the surrounding quartz vein (see picture below). The latter is a smoking gun for the entire locale, compare e.g. the renowned find of huge bornite crystals in the nearby Firschnitzscharte.
