In reply to ScraggyGoat:
Thanks again for the heads up about the how's. Wasn't fairly easy to find in the end. Glad I took your advice as the wind really picked up in the night, very gusty.
Had a cracking day yesterday, took the easier ground left of Dividing Buttress that you mentioned as it looked a bit more interesting that Main Rake, just what I was after, so thanks for recommending that. I've put a couple of photos up in my gallery.
For anyone thinking of heading in there, the track has large sections of ice from the end of the tarmac bit, so very sketchy on a bike. It's a looong walk in without a bike!
