The first attempted ascent was at the Alpine Club of Canada’s special mountaineering camp at Mount Robson in 1913. The Swiss guide Walter Schauffelberger [1881–1915] led Basil Stewart Darling [1885–1962] and Harley H. Prouty [ca. 1857-1916] to within 400 feet of the summit, but they were turned back by lack of time in an approaching storm.
The first ascent was in 1955, by Don Claunch, Harvey Firestone, and Mike Sherrick
