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 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.
