Watch on 123Movies. In 1971, a year after Maestri's ascent to Cerro Torre, filmmaker Leo Dickinson climbed and filmed an attempt on the Compressor Route. Dickinson left only a few pieces of clean protection at his highpoint (the headwall ice towers) and no additional fixed gear. While he and the rest of the team did not reach the summit, his reaction to the bolts on the Compressor Route compelled him to travel to Italy to interview Maestri. The result was this documentary.
