When we have climbed the Mont Blanc 4810m I have used my Garmin Forerunner 910XT to keep a track of each GPS position during all the course. This has allowed me using Google Earth to design the path used
Aiguille du Midi starting point for many routes like Pointe Lachenal, Arete des Cosmiques.
In order to get an other overview of the Mont Blanc and Aiguille du midi, we took the cable car from Argentière (1252m) to the Lognan plateau (1972m) then the Aiguille des Grands Montets (3233m). From here you can see a spectacular panoramic view of the Drus, Aiguille Verte, Aiguilles de Chamonix and Argentière glacier.
