The old story of the Gorges

The Aiguebrun valley is distinguished by its high cliffs with limestone escarpments and its chaos of crumbled rocks. The valley grew hollow about 6 million years after the Mediterranean Sea dried out! The water level will be lowered to 1000m and the rivers that surround it will dig huge canyons which are then filled with sediment deposits. Under the action of erosion during glacial periods, the cliffs will no longer be steep.
