L'Adroit des Muletiers is a huge dam behind which ice accumulated. As it moved slowly, the ice broke through it and came out as a huge frozen waterfall. Because it was probably not carrying much matter which could cause erosion, the ice joined with the resisting obstacle rather than forcing against it. Then, the rock emerged from the ice tongue. A great scree clogged up the foot of the cliff, showing the importance of frost wedging, a process which is still currently ongoing.
