In reply to Bryan W: we were up there yesterday. We did one of the routes next to easy gully.
We thought it was generally pretty buried but there is stuff to do. I guess it week improve significantly when it cold later in the week.
The cornice at the top of the route we did was OK easily turned. I would not say the cornice were huge elsewhere in the corrie but you would need to work to turn or get through them. Some of the cornices were a bit saggy on the sunnier aspects.
