Scientists from the CNRS, Université Savoie Mont Blanc, and the Muséum National d’Histoire Naturelle now know the answer. By studying the landform of the area and making novel use of applied mathematics to date sand transported by the Ardèche River, they determined that the Pont d’Arc was formed about 124,000 years ago.
This study, published in Scientific Reports, reports that these past communities were therefore familiar with the same landmarks we know today: the gorge entrance, a natural archway, and a ledge leading directly to the cave entrance, which was then wide open.
