TThe Aravis mountain range looks like an imposing wall of limestone (it peaks at 2752 m at the Pointe Percée), a veritable mineral monolith defined by a very uniform pattern of glacial cirques. It is composed of several sets of rocks formed in an ancient seabed. Due to Alpine tectonic compression, the mountains were split apart by several faults, compressing one on top of the other to create several groups of cliffs separated by overlaps.
