I also took some video, which I've turned into a stunning piece of cinematography set to the Top Gun anthem.
Aiguille du Midi Telepherique, a two-step lift to one of the Mont-Blanc peaks, around 3900m.
Montenvers railway to the Mer de Glace (sea of ice) Glacier.
We also watched some climbers appearing over a ridge, from where they were presumably returning either from one of the refuges, that seem to have been built on only the most precipitous cliffs of Mont-Blanc, or from summitting the mountain itself.
inside the glacier, from where you can see that in fact it is solid, blue, ice inside, and you can see bubbles of air, pebbles, and even some sizable rocks suspended within.
