The folds of time : discovering the sea via mountains

This didactic itinerary mainly concerns the region of the small valley of Nant (Vaud Alps). It tells the extraordinary story of a tropical water sea which became the Muverans mountain chain. In order to show that our world is not immutable and that the Alps have not always existed, this hike speaks of ancient and present times and spaces of the landscape that have disappeared and those that still exist in order to be able to read the rocks the shapes that constitute it and give the landscape its beauty.

Another of his research themes is the theoretical scientific mediation and practice of the Sciences of the Earth.
