Ballade à Devil's Tower: At the peak of her career as a rock climber, Catherine Destivelle goes to the United States to get away from the competitions and to recharge batteries. There, Destivelle travels by car through Utah and Wyoming to make spectacular free solo ascents in Indian Creek, where she soloes 'Supercrack' (5.10d), in Dead Horse Point State Park, and on the iconic Devil's Tower, where she climbs unroped the second half of the classic 130-foot route 'El Matador' (5.10d).
