In reply to tcb:
Maybe too late with this reply but what the heck. I had some worries when I did the VF later in the season a couple of years ago, but the glacier descent was no problem. It was hard bare ice when I did it and I can tell you there is very, very little in the way of crevassing, so I wouldn't worry too much even if its a bit snowy. If it is snowy, there will probably be a trench. Great VF, especially solo, have a great ascent.
