Anza (river)

The Anza is a 35 km Alpine torrent of the Ossola in northern Italy. It flows from the glaciers of Monte Rosa through the Valle Anzasca and into the river Toce, of which it is a right tributary.

Its own principal tributaries are the Pedriola, the Tambach, the Orlovono and the Quarazza near Macugnaga and the Olocchia at Bannio Anzino.
