Another nice line for Aurelien Ducroz and his team of Doud's Charlet and Adri Coirier. The Chevalier couloir off the Petite Aiguille Verte. Access from the Grands Montets lift then a climb up the North-West ridge of the Petite Aiguille Verte visible from the cable car.
It's a 350 meter couloir, rated 5.2/E2, the start is steep, over 50° and narrow and may require a rope to get to the skiing. After that its 350 m at between 45 to 50°, you fall, you knock yourself around quite a bit.
