Many place names refer to the presence of the bear in the Vercors. The mountains thus preserve forever the memory of the plantigrade now disappeared. In the Trièves, the last of them was shot down in 1898 near the Pas de la Ville, in the territory of Gresse-en-Vercors. The "Tune de l'Ours" is on the eastern balcony of the Vercors. This shelter under rock is thus baptized because it was to serve as shelter to him.

The impressive east gate of the Vercors rises vertically above the Trièves.For nearly 50 km, this crest line, composed of relatively strong Eryonian limestone, extends from north to south at an altitude of about 2000 m (highest point 2341 m with the Grand Veymont).This barrier is difficult to cross, there are only a dozen of Pas to reach the plateau of Vercors.

The shelter of Peyrouse (Abri de la Peyrouse) located on the balconies East of the Vercors is an unguarded stone hut, 2 places are planned to sleep there, but you will not find there water nor stove to warm you.
