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.

Tactical & Camp Notes
Requires world-class 8a technical free climbing mastery on cold mountain granite, micro-footwork on bare crystals, rapid alpine movement, and rime-ice technique.
Identified Objective Hazards
- •Numbing sub-zero rock temperatures making 5.13b friction climbing brutally painful on bare fingers
- •Massive chunks of collapsing rime ice falling from the summit overhang during afternoon warming
- •Rapidly approaching Patagonian gales that can trap climbers on extreme free pitches
- •Severe exposure with thousands of meters of sheer void directly beneath the climbing feet
Historical Context
First freed on January 21, 2012, by David Lama and Peter Ortner in a historic 24-hour push, redefining what is possible in pure alpine style.

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.
