In reply to asdf123:
I've only been there once and it was in summer. We climbed over the top and then down the west ridge to an in-situ anchor from where we abseiled to the foot of the wall. Then we traversed along the foot of the wall to our route. From what I can remember (this was about 10 years ago) the traverse was pretty exposed. Also if you were to do it this way, there's a chance the anchor would be buried under snow.
I think there might be a better option for the approach, but in any case it could well be the most challenging part of the day. The descent via the normal route is very polished and slippery.
