The Graian Alps (French: Alpes grées [alp ɡʁe]; Italian: Alpi Graie [ˈalpi ˈɡraːje]) are a mountain range in the western part of the Alps.




Etymology


The name Graie comes from the Graioceli Celtic tribe, which dwelled in the area surrounding the Mont Cenis pass and the Viù valley.
Other sources claim that the name comes from the Celtic "Graig" meaning rock/stone, literally the Rocky Mountains




Geography


The Graian Alps are located in France (Auvergne-Rhône-Alpes), Italy (Piedmont and the Aosta Valley), and Switzerland (western Valais).
The French side of the Graian Alps is drained by the river Isère (Tarentaise valley) and its tributary Arc (Maurienne valley), and by the Arve. The Italian side is drained by the rivers Dora Riparia, Dora Baltea, Orco and Stura di Lanzo, tributaries of the Po.
The Graian Alps can also be divided into the following four groups:

the Mont Blanc group (north of the Little St Bernard Pass), including the Beaufortain Massif
the Central group (the watershed between the Little St Bernard Pass and the Col du Mont Cenis)
the Western or French group,
and the Eastern or Italian group, including the Gran Paradiso Massif.
