Mount Cervandone, Devero Alp (Devero Valley; Val Devero), Baceno, Ossola Valley, Verbano-Cusio-Ossola Province, Piedmont, Italy

Italian side of Cherbadung, Wallis (Valais), Switzerland http://www.mindat.org/loc-3210.html).
In the rocks under the walls of the mountain often minerals are found coming from the Punta della Rossa etc. (see there).
So you can also take the minerals from the 'Ghiacciaio della Rossa' here. Although they should be cut off...
