A blog about the geology that each stage of TdF passes through.
Stage 16 | Carcassonne – Foix / The vineyard dinosaur
During the stage from Carcassonne to the south, the first part will come through the valley of the Aude. Close to Limoux, the route heads west, and as they progress, the first foothills of the Pyrenees come into sight. The Pyrenees form the crumple zone that formed because Iberia shoved below Europe. Because of erosion of the uplifted southern margin of Europe in the south of France, rocks that formed tens of millions of years ago are now exposed at the surface, and these tell us a story of the Cretaceous and the vineyard dinosaur.
