Description:
From the parking cross the bridge and follow the tracks to the torrent Creuzet and then follow this in to its valley, as you go up the valley bottom you will see the steeper lines including this couloir on the east facing slope, as the trees clear head to the east face and climb the couloir. It’s not great to find on the map as its split between two maps, but easy to spot when there.
Descent:
Ski back down the line you took to get up.
