Official Expedition Narrative & Archival Record

In June 1975, fresh off his triumph on Cerro Torre, Casimiro Ferrari journeyed to Peru's Cordillera Blanca at the head of a Ragni di Lecco expedition targeting the legendary Southwest Face of Nevado Alpamayo (5,947 m). Rising in a flawless trapezoid of fluted ice runnels, the face was widely regarded as too steep and prone to ice avalanches for direct climbing. Operating from a high glacial col camp at 5,400 metres between Alpamayo and Quitaraju, Ferrari, Danilo Borgonovo, Angelo Zoia, and Pinuccio Castelnuovo attacked the central ice fluting. Negotiating a cavernous bergschrund, the climbers front-pointed up 450 vertical metres of 60° to 80° bullet-hard water ice, placing tubular ice screws and chopping delicate belay platforms in the flutings. In the final pitches, Ferrari led through fragile rime mushrooms to break through the razor-thin summit ridge cornice. Reaching the narrow apex on June 23, 1975, their line—christened the Ferrari Route—instantly became the global benchmark for steep Andean ice climbing.

Born on June 18, 1940, in Lecco, Italy, Casimiro Ferrari joined the elite Ragni della Grignetta at age eighteen. Endowed with fierce determination, extraordinary ice-climbing technique, and exceptional mountain leadership, Ferrari turned his attention to the wind-scoured granite spires of Patagonia. In January 1974, leading a formidable team comprising Daniele Chiappa, Mario Conti, and Pino Negri, Ferrari spearheaded the monumental first undisputed ascent of the West Face of Cerro Torre, braving horrific ice mushrooms and weeks of Patagonian storms to reach the summit rim. Two years later, in February 1976, Ferrari returned to Patagonia to make the historic first ascent of the towering East Pillar of Fitz Roy with Vittorio Meles. His exploratory vision extended to the Peruvian Andes as well, where in June 1975 he led the first ascent of the steep, fluted Southwest Face of Nevado Alpamayo, opening what became known as the Ferrari Route. Ferrari spent his later years managing an estancia in Patagonia, where he passed away in September 2001, celebrated across the alpine world as one of the fiercest and most devoted Patagonian pioneers in mountaineering history.
