Congrats Luka Lindic and Luka Krajnc for the first free ascent of the Rolling Stones on the north face of the Grandes Jorasses, Chamonix, France.
This time weather was on your side.
Once again we were able to climb a superb route in our preferred style – simple with minimal gear. We made a first free ascent and managed to on-sight every pitch. We estimate that the hardest pitch is M8, with a scary section climbing over big loose blocks. At least three other pitches are in the M7 range, and several others around M6. However, and as always, numbers do not tell the whole story.
