The Passo dei Salati (2,980 m) is a mountain pass that lies between the Valsesia (Piedmont) and the Valley of Lys (Val de Aosta).[1] It connects the villages of Alagna Valsesia and Gressoney-La-Trinité. The pass has also been known as the Colle Inferiore de Pisse. The term salati recalls an ancient passage of Roman soldiers.[citation needed]
