In reply to Suncream:
There is a major couloir on the South side but it is not super obvious from what is a tricky descent ridge from the top of the Chardonnet. That ridge also gets a lot of misty weather
I've skied the South Couloir in winter (climbing up it first) and i wouldn't want to be on it without skis (its both steep and avo prone), or there without significant snow (there's a huge amount of choss)....
Why not take the normal descent to the Alb Prem hut?
