Grands Charmoz and Aguille Sans Nom, French Alps. On October 19 and 20, Mark Twight and Scott Backes climbed a very difficult new 10-pitch route on the west face of the Grands Charmoz. It was mostly ice and mixed climbing with one pitch of A2. On October 27 and 28, the same pair made another difficult new route on the north face of the Aiguille Sans Nom. The 900-meter route had vertical ice, difficult mixed climbing and one A3 pitch on loose flakes. On both of these routes, much of the ice was very thin. These peaks rise above Chamonix in the Mont Blanc region.
