  Gresse-en-Vercors is a small ski resort of 400 inhabitants, nestled between the eastern border of the Vercors and the Serpaton mountain pasture. The village church was built in the traditional style of the old mountain chapels. It is the oldest monument in the Gothic style of the region. Its construction goes back to the 13th century for its lower part. A great quantity of its very beautiful stones were carved on the high plateaux of the Vercors at about 1800 meters of altitude.

• Murgers

  The name would come from a Burgundian word. It is true that from Bourgogne to the Ardèche, the stones grow well in limestone fields! These piles of pebbles at the edge of the field are the result of the stoning patient, over time, realized by generations of obstinate peasants to gain arable land. Sometimes, they are mounted in low walls to delimit enclosures and plots.It is also a beautiful refuge for rampant wildlife in search of shelter.

• Life in the rock

  In scree slopes, life conditions are difficult for plants, and the fallen rock debris can become unstable and migrate slowly downslope by solifluxion. Many different strategies can be adopted by plants to survive. 
  
  Studies conducted in the Pyrenees have shown there are two strategies:
  1/ Immigrant lithophilic plants can anchor and extend their roots even while the rockslides are moving,
  2/ Some trees such as hook pine are able to stretch
  their trunks while remaining anchored far upslope.

• Mont Aiguille

  The Mont Aiguille, from its 2087 meters, is a mound of the eastern barrier of the Vercors. Indeed, the Mount is composed of the same materials as the rest of the plateau (limestones and marls deposited by the sea before the rising of the Alps) to which it was formerly attached. The most tender limestones and the presence of numerous faults facilitated the dissolution of the limestone over time, leading to the isolation of Mount.

• Chapel of Trézanne

  Nestled at the foot of Mount Aiguille, the Chapel of Trézanne offers a magnificent view of this majestic mountain, overlooking it more than 1000 m. This small Romanesque chapel is characterized by its thatched roof which was rehabilitated in 2001 and recently renovated. Before the eighteenth century, the thatched roofs were numerous in the Trièves: they were gradually replaced by tile roofing, notably because of the fires.

• A giant with feet of clay

  The foot of Mont Aiguille is carved out of marl, a rock sensitive to gullying and scouring. One day, a whole section of this face will collapse due to recession of the gullies. In this way, the Mont Aiguille will gradually disappear through successive rock falls.
