Dauphiné Alps
The Vercors Massif is a range in France consisting of rugged plateaux and mountains straddling the "départements" of Isère and Drôme in the French Prealps. It lies west of the Dauphiné Alps, from which it is separated by the rivers Drac and Isère. The cliffs at the massif's eastern limit face the city of Grenoble.
