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 1980, Bill Denz (New Zealand) attempted the first solo of the Compressor Route. Over a five-month period, he made 13 concerted attempts but was driven back by storms on every occasion. On his last attempt, in November 1980, he got to within of the summit. In January 2008, Rolando Garibotti and Colin Haley made the first complete traverse of the entire massif, climbing Aguja Standhardt, Punta Herron, Torre Egger and Cerro Torre together. They rate their route at Grade VI 5.11 A1 WI6 Mushroom Ice 6, with total vertical gain. This had been "one of the world's most iconic, unclimbed lines", first attempted by Ermanno Salvaterra. 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. On 16 January 2012, American Hayden Kennedy and Canadian Jason Kruk made the first "fair-means" (a term used to describe a reasonable use of bolts for safety and aesthetics, "a long-accepted practice in [the Patagonian] mountain range") 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
