In reply to DougG:
This is a tragic story and one that could have easily happened to me and from the sounds of another posting to some others that very same day.
We were climbing as a rope of 3 and when we got to the Eastern traverse there was 6 folks ahead of us with the leader of the first rope practically stuck through nerves/lack of bottle exactly half way across.
After half an hour of waiting we decided that if we didn't descend we would be benighted. However during the day the snow had softened so even the easier sections were treacherous and we abseiled most of the ridge. (comments on how dumb this is appreciated). Because the ridge is so long and there was 3 of us and it was dark, it took ages, with the ropes jamming repeately. Then it started to snow.
I remember sitting on a ledge after one abseil in the pitch and freezing darkness waiting for the other two to join me, they took ages as it later turned out due to rope jams. I got so cold that I started to hallicinate that I was in a nice warm bed with my wife...
Anyway, we finally got off and back to the car for about 1am all safe and well.
So what lessons can we learn from this? I am sure my fellow posters will have a few.
For me, it was early in my climbing, I realised that our skills were not sufficient, our knowledge of retreat and any other options was none existant... and even if all of that was fine, sometimes, on a route, you are dependent on the actions or inactions of others.
Also, for any novices out there do not underestimate Tower Ridge.
Cheers
