After our attempt at the Tour Rond the previous day, Ragnar and I stayed at the Cosmiques Refuge and then headed up Mont Blanc the following day.
The slog up got hard for about the last 200m of climbing, but other than that it was all good. The descent was awesome straight down the North Face. Its not particularly steep of challenging. Just a case of not hanging around when in serac danger areas.
If you look carefully you can see a little black dot in the center, which is Ragnar, and our tracks.
