Fitz Roy. In December of 1976 Ruedi Homberger, René Major, Paul Muggli and Jean Troillet, Swiss, climbed the American route on Fitz Roy in four days. In late January Mike Weiss and the Frenchman Jean Afanassief made a 19-hour ascent of the Super Couloir and descended in another twelve. South Africans, Dave Cheesmond and Phil Dawson, had nearly climbed the whole couloir when bad weather forced them back. The British climbers Alan Rouse and Rab Carrington made an attempt on the west face, climbing 5000 feet in two days, but doubtful weather and uncertainties for a retreat made them call off their try.
