In reply to BlueTotem:
I recall I was at the foot of the Aiguille du Pouce, precariously balanced on the edge of the bergrshrund, kitting up along with lots of other parties there, all trying to be the first to kit up and get going.
Just as I was buckling my harness, I realised I had to go. I reckoned I had about 10 seconds warning. Dropped my harness, and my keks, and dumped into the bergschrund. There was no other option whatsoever.
At least it was now out of sight, but I'm sure, to many others, not out of mind.
