At the foot of the Black Combe, on the site of the fountain of Machiret, several thousands of objects in flint were discovered following the erosion of the path of the Col de l'Arc.The site was frequented during the Mesolithic period (9,500-6,500 BC). Some of the objects are shaped from the flint present on the slopes of the Cornafion. However, some of these pieces are made of flint from the south of the Vercors. Others are made of hyaline quartz and come from the crystalline Alps.This shows the great mobility of the last hunters of Prehistory, who found here a propitious place to stay during their hunting expeditions at altitude.
