The run down the couloir was enjoyable but not quite what we had worked for. The bottom half was severely rutted but the previous day's avalanche. In places there were 3 foot deep ruts carved into the hard snow base with plenty of rocks pointing through. And as is usual, just as we stated the descent the clouds closed in heavily and all contrast was lost, making the rutted hard packed descent a little bit more difficult and less fun.
Once at the base of the couloir we rode unfortunately heavy spring snow down the very long Saliena Glacier to Praz de Four in Switzerland where we had a beer and then paid €170 for a taxi-van ride back to Argentiere, which by this stage was a long way away from where we were.
All up it was a great two day and one of the longest descents I have made. Once you reach the summit of Aiguille de Argentiere and look east into Switzerland you enjoy quite a remote aspect of descent with no lifts or ski resorts. It is a less trampled section of the massif and worth the effort to get there.
