The Brenva is a great place near Monte Bianco. In fact, the Brenva Glacier originates at this highest mountain of the Alpes! Alpine minerals like cabinet size Smokey Quartz, Iron Rose (Hematite), micro Anatase (a rare TiO2 mineral) and others can be found in the Murene. This is the edge of the Glacier, made out of rocks transported by the ice. There is a constant but slow movement downwards and by melting of ice. Murene tends to be dangerous and quite steep. The yellow Kasolite, an uranium mineral, is very rare.
