The new 1:25,000 geological map of Mont Salève (Haute Savoie, France), published in 2023, has revealed many secrets, including previously unknown faults, which are of particular interest for geothermal research in the Geneva region. The Petit and Grand Salève, which rise to a maximum height of 1,309 m, are part of a NE-SW «knee» anticline. The «Genevan mountain» is made up of the same rocks as those of the southern Jura, so geographically it belongs to the Jura.

During the hike, which begins at the top station of the cable car, you will discover, among other things, traces of shrimps that once lived in a lagoon, and coal seams that bear witness to marshes dating back 140 million years. Near the Rochers de Faverges, you can still find slag from iron extraction in the Middle Ages and Roman times.
