In 1977, the first
Alpine style ascent was completed by Dave Carman, John Bragg and Jay Wilson (USA). They took a week to summit Cerro Torre, which had taken the Italian group two months to summit. In 2010, Austrian climber
David Lama was held responsible for around 30 new bolts and hundreds of meters of fixed rope added to the Compressor Route on the mountain (due to bad weather conditions, much of the gear was left on the mountain and later removed by local climbers). Although the bolts were drilled by Austrian guide Markus Pucher, and not by Lama himself, it was done as part of his trip sponsored by Red Bull, and many climbers regard Lama and
Red Bull as responsible. Many of the bolts were drilled next to cracks, which are usually used by climbers for protection on the route. This has caused a large controversy in certain climbers' circles, as his actions are unethical according to climbing purists. Although Lama was not aware of the sheer number of bolts that were drilled, he took full responsibility for the actions. In the upcoming years, he publicly regretted what happened. ascent of the Southeast Ridge, near the controversial Compressor Route, using only two of Maestri's original belay anchors on the headwall. After summiting, Kennedy and Kruk removed 125 of the bolt-ladder bolts during their descent. Colin Haley, who watched the ascent from Norwegos, estimated the climb took them thirteen hours from their bivy on the shoulder to the summit. "The speed with which they navigated virgin ground on the upper headwall is certainly testament to Hayden's great skills on rock", Haley reported. There has been much discussion concerning the removal of bolts from the compressor route by Kennedy and Kruk. However, the consensus amongst the climbing community is that of agreement for removing the bolts and it has embraced their actions as having "restored Cerro Torre's southeast ridge to the realm of genuine adventure". In contrast to David Lama's free ascent (also "fair-means"; January 2012, together with Peter Ortner), Kennedy and Kruk used bolts, although not Maestri's, during their ascent. Lama estimated the difficulties of his free ascent, which followed a new line circumventing the bolt traverse and in the upper headwall, as grade X− (hard 8a but mentally highly demanding; e.g., climbing on loose flakes, long runouts). Lama stated that a free repetition of the original Compressor Route is virtually impossible, in particular as the rock of the last pitches comprise no climbable features. ==Notable ascents and attempts==
