You can see tourists and climbers on the left for scale plus there's a group of climbers heading up the serac-strewn slopes that are down and to the left of the summit (which I think is the popular Three Monts route to the summit but the trail stops half-way up the slope. So if anyone can tell me why folk would be traversing under ice seracs at 11am when the sun is shining, I'm really curious to know - my understanding being that's just silly dangerous and folk usually summit Mont Blanc at dawn when the slopes are frozen).
