The line starts down the glacier from the top of the Girose / 2nd Trifides drag lift. Follow the fall line heading almost directly under the Dome de la Lauze. Just before the small flattening, head skiers right to cross over before the rock face and seracs. Ski the tongue of the glacier to the right of a shoulder. Follow the series of bowls and gullies but make sure you catch the traverse off left to avoid the deep gorge below. When you reach the obvious square rock in the middle of an exposed slope, continue descending very slightly skiers left, until two larch trees. A rope can be useful for the traverse. A fall would almost certainly be fatal. Enjoy the final few turns before reaching the bridge to cross over to the main road.
