In reply to mark hounslea: I guess it depends on the conditions when you get there. In Aug 2003, there was no snow so yes, we did it entirely in trainers + rock boots.
As a result, no axes were required.
We bivied 2/3 of the way to the foot of the North Ridge due to a lack of daylight but you can bivi there.
The N ridge was okay as a descent although not easy to find a couple of the abseil rings. We then downclimbed solo the lower section of the ridge. We left the col at about 6:30am ish and probably got back there at 7pm ish. The route took 6hrs, the descent 5hrs. However, it saved a night at the hut and a days walk back.
