description Compressor Route Overview
The Compressor Route remains one of Patagonia’s most challenging and controversial climbs on Cerro Torre. Cesare Maestri established this alpine route in 1970 by employing a compressor for placement, a technique rarely used today. It demands exceptional technical skill, physical fitness, and experience with fixed lines and ice protection. The route is primarily intended for advanced climbers familiar with extreme conditions and demanding multi-pitch ascents seeking a historic and exceptionally difficult Patagonia challenge.
help Compressor Route FAQ
Why was Cerro Torre's Compressor Route so controversial?
Cesare Maestri's 1970 expedition used a gasoline-powered compressor to drill hundreds of bolts into the mountain's upper rock. Critics argued that this level of mechanical alteration violated the self-reliant ethics associated with alpinism.
Did Cesare Maestri reach the true summit of Cerro Torre in 1970?
No. Maestri stopped below the summit's overhanging ice mushroom and declared that feature not part of the mountain. Later climbers continued through the ice formation to stand on the accepted summit.
Why were bolts removed from the Compressor Route?
In 2012, Hayden Kennedy and Jason Kruk climbed much of the southeast ridge while avoiding many of Maestri's bolts, then removed a large number during their descent. The action triggered an intense debate about whether later climbers had the right to erase part of a historically significant route.
Can climbers still follow the original Compressor Route today?
The southeast ridge remains climbable, but the 2012 bolt removal changed the original bolt-dependent line. Modern ascents require serious Patagonian alpinism skills, including rock, ice, route-finding, and the ability to cope with Cerro Torre's severe weather.
