Photo prise à : Annot, Alpes-de-Haute-Provence

We walked for a 3-hour loop hike marked "Grès d'Annot" . The trail goes through shady woods and forests and, at one point, follows around the side of a sandstone (grès) cliff that dominates the Vaire river valley. The grès (in Grès d'Annot) is a sedimentary sandstone rock created about 60 million years ago when this area was under the sea. Grains of sand were pressed together under intense pressure and cemented together by a natural silicon or calcium cement. The sandstone cliffs were exposed by several million years of glacial and fluvial erosion. Source: www.beyond.fr
