The Chavière accident

Ÿou are not witnessing a pile-up of vehicles but a pile-up of two geological formations of different ages. Looking north, on your left, is the coal-shale part of the Vanoise with dark rocky cliffs (rocks dating from -360 to -295 million years). To the left, beyond the summit of the Schwarzhorn is the “crystalline” Vanoise, which is not visible from this point. The Schwarzhorn is located between these two formations.
