Colossus with a foot of clay

The foot of Mont Aiguille is shaped from marl, a sedimentary rock that is prone to gully erosion and scouring. These numerous ravines are clearly visible on the south-eastern side. At the foot of the rock wall, the keen eye can make out huge blocks that come from the mighty limestone wall of Mont Aiguille. An entire portion of this wall collapsed one day due to the retreating ravines. This is how Mont Aiguille disappeared little by little following one collapse after another.
