SW Ridge from Cab. de Arpitettaz Date Climbed: Sep 17, 2014
Had a bit of an adventure, I wouldn't recommend the route in "Mud Season" unless all climbers in the party are super confident, there was a lot of loose crap on the the north side of the arete for most of the way. The 4th class stuff on the arete was actually pretty good, there are a couple of pins in place but it could be nice to have a small rack from .4 - 2 camalot or so.
We descended north towards the cabane de tracuit and then took a scree run and glissade down the west face and snowfield, which was very efficient but beware of potential rock fall from the ridge.
There is a good trail towards Zinal the runs parallel to the river so no reason to climb back up to join the trail from the cabane de tracuit.
