The Saut de la Saisse is a waterfall in France located in the Jura massif, at the point where the Ain river flows into the Vouglans reservoir at Pont-de-Poitte and Patornay, between Lons-le-Saunier and Clairvaux-les-Lacs. A "marmite du diable", "marmite de géant" or "marmite glaciaire" in Switzerland (or simply "marmite" or "chaudron") is a more or less cylindrical natural cavity carved into the rock by ancient, generally torrential watercourses, carrying pebbles or gravel, which promotes swirling erosion (a phenomenon called "marmitage").
