In the 1950s he pioneered new rock climbs, most notably Grillmair Chimneys (1952), Calgary Route (1953) - with Franz Dopf leading, and Diretissima (1957) on Yamnuska. He made the third (and first Canadian) ascents of both Mount Alberta (1958) and Brussels Peak (1960). He participated in what may have been the first ascent of Alaska's Mount Blackburn in 1958, and led very successful expeditions to Mount Logan (east ridge) in 1959, and to Mount McKinley (Wickersham Wall) in 1963. In 1961 he climbed a difficult new route on the south face of Mount Louis. He was described as a good leader. He always had plans and he did his darndest to make his dreams come true.
