Pizzo dell'Arzo, Ghiacciaio dei Cavagnoli (Ghiacciaio dei Cavagnöö), Val Bavona, Valle Maggia, Ticino (Tessin), Svizzera (Schweiz; Suisse)


The area limited in the south by the watershed ridge Pizzo dei Matörgn (2903 m) - Pizzo dell'Arzo (2755 m, Swiss coordinates: 681'020 / 144'410), in the west by the ridge descending northeastwards from Pizzo dei Matörgn to Lake Cavagnoli, in the north by the same lake, and in the east by Cresta dell'Arzo (the ridge descending northeastwards from Pizzo dell'Arzo to Lake Cavagnoli) is extraordinarily rich in mineralised clefts.

Well-known mineral areas are:
- the so-called Fianca d'Arzo, which in the 1960s was still covered by a branch of Ghiacciaio dei Cavagnöö, located to the west of Pizzo dell'Arzo between Lake Cavagnoli and the newly formed glacial lake at 2450 m below the lower glacial cirque;
- the area to the west of Pizzo dell'Arzo between the lower and the upper glacial cirque;
- the so-called Mezzalingua, an already ice-free area in the 1960s, where in 1965 the "strahler" Gilberto Leonardi made an extraordinary find of quartz and adularia crystals;
- the north slope of Pizzo dell'Arzo between 2450 and 2750 m;
- thenortheast slope of Pizzo dell'Arzo with the euclase-bearing cleft system;
- the Cresta dell'Arzo ridge.
