Mont Blanc Massif
The
Mont Blanc massif; ; ) is a mountain range in the
Alps, located mostly in
France (
Haute-Savoie and
Savoie) and
Italy (
Aosta Valley), but also straddling
Switzerland (western
Valais) at its north-easterly end. It is named after
Mont Blanc which, at 4,810 m, is regarded as the highest point in western Europe. Not only does the massif form a
watershed between the vast catchment areas of the
Rhône and
Po rivers, but it also marks a border between two climate regions by separating the northern/western Alps from the southern Alps.
