Name(s) in local language(s):
Alpe Sponda - Pizzo Forno, Val Chironico, Leventina, Ticino (Tessin), Svizzera (Schweiz; Suisse)


Classic locality for blue (Fe-bearing) kyanite in white mica (Na-bearing muscovite or paragonite).

Two closely related places, and actually only one locality. The Sponda Alp (Alpe Sponda) is located on the south slope of Pizzo Forno.
The grid reference marks the summit of Pizzo Forno (2907 m, Swiss coordinates: 702´860 / 143´285).
