Col de Crête Sèche
The Col de Crête Sèche is a mountain pass in the Alps, located between Switzerland and Italy. It lies at a height of above sea level, between the massifs of Mont Gelé and Bec d'Epicoune, in the Pennine Alps. It connects Fionnay in the Swiss canton of Valais on its northern side to Bionaz in the Italian region of the Aosta Valley on its southern side.
