2012 David Lama Cerro Torre First Free Ascent Expedition
On January 21, 2012, Austrian climbing prodigy David Lama, alongside Peter Ortner, achieved the historic first free ascent of the Southeast Ridge of Cerro Torre, climbing the sheer granite headwall without clipping a single artificial bolt from Cesare Maestri's compressor line.

Official Expedition Narrative & Archival Record
In January 2012, Austrian climber David Lama returned to Patagonia for his third season on Cerro Torre, determined to free climb the Southeast Ridge (3,128m). Days before their push, climbers Hayden Kennedy and Jason Kruk had made a fair-means ascent and chopped out approximately 120 of Cesare Maestri's bolts during their descent. Unfazed by the missing hardware, Lama and climbing partner Peter Ortner seized a pristine weather opening on January 19. Leaving the Col de la Paciencia, Lama led every technical pitch free, navigating blank granite slabs on microscopic crystal edges with numbed fingers. Reaching the upper headwall—where Maestri's bolts had once formed an artificial ladder—Lama traversed slightly left onto steep natural cracks and blank friction facets. Moving with supreme poise thousands of meters above the Patagonian icecap, Lama unlocked sequences up to 5.13b (8a) on cold mountain granite without pulling on or clipping any bolts. Passing the iconic abandoned compressor, Lama and Ortner scaled the summit rime mushroom and stood on the summit of Cerro Torre on January 21, 2012, accomplishing one of the greatest free climbing achievements in alpine history.

Ascent Route & Topography

Compressor Route (Southeast Ridge)
The Compressor Route along the Southeast Ridge of Cerro Torre is one of mountaineering history's most renowned and debated lines. Initiated in 1970 by Italian climber Cesare Maestri using an Atlas Copco gas-powered air compressor to install roughly 400 expansion bolts up blank headwalls, the route was completed to the true summit in January 1979 by American climbers Jim Bridwell and Steve Brewer in an audacious alpine-style push.

Southeast Ridge Free Line (Lama Route)
The Southeast Ridge Free Line on Cerro Torre is one of the crowning triumphs of modern free climbing. First envisioned and freed in January 2012 by Austrian prodigy David Lama, alongside Peter Ortner, the route free-climbs the sheer, exposed granite of the Southeast Ridge without using Cesare Maestri's artificial bolt ladders, establishing a pure line rated 5.13b (8a) up to the summit rime mushroom.
Target Objective Peak
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.
Featured Expedition Climber

David Lama
David Lama was born on August 4, 1990, in Innsbruck, Austria, to an Austrian mother and a Sherpa father from the Solukhumbu region of Nepal. Discovered at age five by legendary mountaineer Peter Habeler, who was astonished by the young boy's innate balance and climbing talent, Lama became the most decorated youth competition climber in history, winning multiple World Cup titles in both bouldering and lead climbing as a teenager. Transitioning from indoor plastic climbing to extreme alpine rock and ice, Lama set his sights on the supreme prize of big-wall climbing: the first free ascent of the Southeast Ridge (Compressor Route) of Cerro Torre (3,128m) in Patagonia. After initial controversial attempts in 2009 and 2010 where a film crew placed bolts, Lama matured as an alpine purist. On January 21, 2012, accompanied by Peter Ortner, Lama achieved the monumental first free ascent of the Southeast Ridge (5.13b / 8a), climbing the sheer, vertical headwall without clipping a single bolt from Maestri's compressor line and bypassing blank sections with delicate natural friction traverses. In the Himalayas, Lama pursued pure, unassisted exploration. In October 2018, having previously attempted the unclimbed 6,895-meter Lunag Ri on the Nepal-Tibet border with American veteran Conrad Anker, Lama returned to the mountain alone. In a continuous, solitary push in sub-zero cold, Lama made the historic first ascent of Lunag Ri via its knife-edge West Ridge, an ascent hailed worldwide as a masterpiece of modern solo alpinism. On April 16, 2019, while descending after completing the difficult M16 route on Howse Peak in the Canadian Rockies alongside Jess Roskelley and Hansjörg Auer, Lama was swept away by a colossal avalanche and killed at age twenty-eight. He was posthumously awarded the 2019 Piolet d'Or for his triumph on Lunag Ri.
