From the top of the Aiguille chair, hike or skin 45 minutes up the ridge to your left to the highest point. The huge north face reveals itself only once you reach the top. The face is often guarded by huge cornices which dictate a variety of different entry points. The upper pitch is wide, steep, and can be prone to huge avalanches, so be extra sure of snow conditions before you set off. It is this same breadth, altitude and northerly aspect though that means the snow can still be cold, powdery and untracked many days after a storm. The whole descent offers 1500m vertical of skiing in an away-from it all backcountry environment.
