Between the rocks of Ranc des Agnelons and the rock of the Cornafion (2,049 m), at the foot of the Vert pass, is the site of Roybon, frequented by the hunters of the Mesolithic towards 7,000 years before. J-C.More than 500 flakes, tools and armor of flint arrows were found near the creek. The raw material is essentially local. The presence of a quartz shard from the Alpine crystalline massifs shows the mobility of these human groups.Thus, the presence of water in Roybon certainly favored the stay of prehistoric men on the site during their ibex hunting expeditions.
