FATMAP difficulty grade
This popular line - or rather bowl - is a large open area at a consistent gradient that offers excellent skiing and plenty of space for you to choose your own line.
Warning: The area is known for avalanches so be sure to check conditions.
From the Col de Chassoure, traverse high and right towards the ridge and the Col de la Mouche.
From here you can choose to continue traversing into the main bowl or ski directly down from the Col de la Mouche.
Follow the valley to Tortin.
