The Annot sandstone boulders

Covered with lichen, the Annot sandstone boulders have quite large grains; their rounded shape tells a story, that of a journey within a glacier 10000 years ago, from the mountain far upstream, which ended with the slow process of erosion by the waters of the mountain stream.Bare and with sharp edges, there are blocks of limestone that the freezing weather, increasing the size of the cracks, separated from the nearby cliff.
