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").

Climbed it today (17-8-25); it's open, and there are signs along the road showing your progress. Traffic is quiet, and a beautiful green climb, especially further on.
