Mountain refuge Bergerie de Jasneuf

Map reading in the Vercors

The clear thing when planning the Bergerie de Jasneuf is its territorial role: it appears in the sector of Chichilianne, on the senier des rochers du parquet and within the massif of the Vercors 1627 meters. This combination places it in a range of medium-high calcareous mountain where the shelter works less as an isolated destination and more as a useful reference between crossing routes. In this environment they link long-distance routes such as Traversée du Vercors by the GR 93, the GR 91 of the North-South crossing and the GTV or Tour du Vercors à pied, so that its location can serve to divide day, reorganize a stage or resolve a withdrawal if weather, tiredness or orientation force to shorten.

Step point and withdrawal margin

The near relief helps to understand that practical use. Towards the immediate environment there are elevations such as Tourte-Barreaux the Rochers de Plautret or Tête de la Graille , modest summits at absolute altitude but sufficient to fit steps, create highlights and demand careful reading of the ground. In the area of Chichilianne the reference of Mont Aiguille , great milestone of the eastern edge of the Vercors, which gives context to a landscape of limestone walls, balconies and trails where it is not right to be trusted even if the shelter is located near the map. This is precisely why it can be valuable as an escape point: not so much as a basis for concrete ascension, but as a support in a network of roads where an orderly withdrawal is worth more than forcing the itinerary.

Reasonable autonomy is needed. The invented sources are several kilometres away, none particularly close, so it is not wise to take immediate water for granted in the shelter environment. Nor should we assume services or equipment beyond their existence as a mountain coat. For those who travel this sector of the Vercors, the key is to use it as a reference of navigation and safety: to place well their position with respect to the rochers du parquet, to contrast mapping and to anticipate alternatives before entering a long stage or exposed to the change of time.
