I had spied this line I wanted to ski and with the good weather the west facing lines were turning into lush velvet corn so the day I had no one to ski a with I went on a training run from Le Buet to Col Cornes de Loriaz in 2.75 hrs on heavy AT kit (the cornices getting sun on the east face above motivate you!). I hung out on the col for 45 mins to allow the snow to soften then was able to join the couloirs on flat lush spring snow without taking my skis off.
