Grésivaudan

Etymologically, Graisivaudan comes from roots meaning "Grenoble" (Gratianopolis) and "valley".

[1] It comprises the alluvial plain of the river Isère from Grenoble to the confluence of the Arc; or, more recently, the entire valley of the Isère from Tullins to Albertville.

Under the Köppen system, the Grésivaudan valley is on the boundary between the humid continental and the oceanic climates.

Winters are cold and moderately snowy, while summers are hot and slightly drier.
