Wednesday, 21st of May 1997:    Marvejols - Sainte Énimie - Millau

We now left the "Central Massif" behind and entered the region of the "Causses". The "Causses" are built up by limestone-layers of Jurassic age (208-144 million years old). The presence of limestone indicates that, during the Jurassic age, this area was a sea.

After the Jurassic age, the area was lifted upwards due to tectonics, creating a large limestone-plateau. Then rivers started to cut into the plateau and created up to 400 metres deep canyons ("gorges" in French) that divided the plateau into separate parts, called "Causses".

This picture below is taken near the village of "Sainte Énimie". You see the river "Tarn", that cut the deep "Gorges du Tarn", dividing the plateau into the "Causse de Sauveterre" on the right and the "Causse Méjean" on the left.
