Cesare Maestri demonstrates rock climbing technique by making an ascent in the Sella Group in the Dolomites. Maestri starts by climbing a fourth and fifth grade route. Then he progresses through a sixth grade rock face, and ends climbing a roof using aid climbing techniques. Maestri, nicknamed the 'Spider of the Dolomites' is known for his solo repeats in the Dolomites, as the first climber in the world to ascend the sixty-year walls, and for the controversial first ascent of Cerro Torre in Patagonia.
