Diadem Peak

Diadem Peak rises in Jasper National Park’s Sunwapta River Valley as the high point of a ridge descending from Mount Woolley. In the Canadian Rockies, it holds an unusual place in mountaineering history as the first eleven-thousand-foot peak north of the Columbia Icefield to be climbed and one of the few summits in the range reached before 1900. J. Norman Collie, Hugh Stutfield, and Hermann Woolley first ascended it in 1898 after abandoning an attempt on Mount Woolley, naming it for the crownlike cap of snow they found on top. Later climbers opened additional routes, and the peak remains a noted climbing objective.
