Archeotrail: the hunters of Prehistory
The outcrops of flint of Plâtres
The north of the Vercors is characterized by the abundance of the lodgings in the Quatre-Montagnes area, to which the outcrop of the Plâtres Senonian flint belongs.
The search for the geographical origin of flints carved by men during Prehistory can make it possible to understand the circulation of human groups within the territories they frequented.
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.
Point of view of the Côtes
This landscape is marked by the presence of external lateral moraines forming parallel cords, originating from rocks torn off and transported by the glacier that occupied the valley of Fauge 20 000 years ago.
Some erratic blocks, which are found in the center of the village of Villard-de-Lans, have been transported by this glacier and come from the ridge between Pas de l'Œille (1960 m) and Pré Achard .
Clos de Lans area
More than 1,000 objects in flint were discovered as a result of work carried out for the capture of the nearby fountain. Most of these objects were fashioned on flint found at the foot of the slopes of the Cornafion.
It is the presence of water and flint, as well as the good exhibition of the site that attracted the hunters of Prehistory on this place, which presents a small flint-sized workshop.
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.

Staying on marked trails also means respecting private property.
Beware of rain or fog, some passages can be slippery and technical.
You will be going through the summer pastures, maybe you will meet protective dogs and herd guards.
Always be sure to bypass the animals while remaining calm while the dog identifies you. Do not pet him or threaten him.
If you have a dog, keep it on a leash!
