Cerro Torre West Face (Via dei Ragni)
The Via dei Ragni (Ragni Route) on the West Face of Cerro Torre is widely regarded as one of the world's most aesthetic, difficult, and prestigious mixed alpine ice climbs. Pioneered in January 1974 by Casimiro Ferrari, Daniele Chiappa, Mario Conti, and Pino Negri of the Ragni di Lecco, the route ascends 600 metres of vertical granite, sheer mixed gullies, and towering vertical rime-ice mushrooms (graded AI5+ M4).

Tactical & Camp Notes
Approached across the Southern Patagonian Icefield through the Circo de los Altares, climbers establish high camps beneath the colossal west face. The climb tackles mixed granite runnels, the steep Col de la Esperanza, the Elmo ice mushroom, and vertical rime towers where climbers must hollow out tunnels through unprotectable frost feathers to attain the summit rime plateau.

Mountain Ascended
Cerro Torre
Cerro Torre is a world-famous granite spire rising to 3,128 meters in the Southern Patagonian Icefield on the Argentina-Chile border. Renowned for vertical sheer granite walls topped by monstrous rime-ice mushrooms formed by relentless Pacific winds, it is widely considered one of mountaineering's supreme technical challenges. Following fierce international debate over Cesare Maestri's disputed 1959 climb, Maestri returned in 1970 to drill hundreds of bolts using a gasoline compressor on the Southeast Ridge. In 1979, American pioneers Jim Bridwell and Steve Brewer completed the historic first definitive ascent of the Compressor Route to the summit.
