This photo makes me wonder whether you could climb Mont Blanc first and then descend the Peuterey Ridge to do the Aiguille Blanche. Is this a feasible idea do you think?
these days everything seems to be feasible...why should one do it this way? If you want to climb Aig. Blanche there are nice other routes such as the North Face which we did on our way to the Peuterey Ridge or the South Ridge via Aig. du Peuterey
