The Jura massif provides a long geological history. The limestone rocks formed during the Mesozoic era, between -170 million years and -90 million years. Much later, the pushing of the Alpes led these rocks to fold, between -11 million years and -3 million years. Lastly, the erosion caused by the icebergs, the freezing, the water and the wind, have progressively shaped the landscape.
And Man has made the final contribution through farming and development.
