In reply to Euge:
Saw the team in No. 5 just as they headed to the massive cornice. They bypassed it to the left but still seemed a bit risky being up there.
We did Vanishing Gully which was ok going, good ice on all the moves but it wont be there long. Tower ridge was a lot firmer, good placements throughout. There were two guys at Tower Gap who kindly let us go ahead. Would be good to know if they made it before it got dark. Also we've got some photos of them on the gap and I think they got some of us so would be good to hear from them.
Also noticed some large cracks in the snow slope between Tower ridge and Observatory gully. A lot of movement on the entire slope.
