Documentary featuring the ascent of the Matterhorn (Cervino) completed in 1911 by Mario Piacenza along the guides of Valtournenche Joseph Gaspard and Joseph Carrel . The ascent was filmed by Piacenza from the Italian side, by the Lion Ridge. In the film, a party of four climbers ascend from Cervinia to the Colle del Leone. From there they start the real rock climbing. The team ascend the chimney using a fixed rope with knots to reach the Luigi di Savoia Hut at 3830 meters and later, the snow covered Tyndall Peak. Finally the team arrive to the Italian summit and two men cross to the Swiss side. The film ends with a panoramic of the Matterhorn from Zermatt, suggesting the descent down the Swiss face.
