FATMAP difficulty grade
Follow the itinerary for the Arare couloir, but once on the summit of the Hauts Forts descend via the western ridge that gradually tapers down towards the top of the Nant d'Ankerne (Encornette) couloir.
Pass by the entrance of the couloir and ascend the steep slope to the west summit (2,359m).
From this point you can ski as far along the ridge to the west as you like before dropping into the face and enjoying an excellent off-piste pitch with a multitude of lines all the way down to the forest.
There are often many tracks in the lower half of the face that are easy to follow through the woods to reach the piste down to Prodains.
