In 1961, Tullio Rigacci filmed a mountaineering excursion on Gran Zebrù, a symbolic peak of the Ortles-Cevedale group (3,857 m). The footage shows a group of friends at high altitude, immersed in a landscape of abundant snow, as they prepare for the ascent. They proceed roped together along the white slopes, advancing with ice axes and period equipment, across snowy ridges and steeper sections of the glacier. The camera alternates close-ups of the companions marching with panoramic views of the surrounding mountains, dominated by the elegant, pyramidal profile of Gran Zebrù, known for its steep slopes and characteristic snowy summit ridge.
