almost every horizon. Collie later wrote: In 1900, former British clergyman James Outram came to the Canadian Rockies to recover his health after a nervous breakdown. The following year he made the first ascent of Mount Assiniboine (), then considered the "Matterhorn of the Rockies". In 1902, Outram made ten first ascents of peaks over and discovered four new mountain passes in the Columbia Icefield area. Two of his first ascents in 1902 were Mount Columbia () and Mount Bryce (), one of the most dangerous and difficult summits in the Rocky Mountains. Following World War I, other mountaineering firsts occurred. In 1923, American climbers James Munroe Thorington and W. S. Ladd joined Austrian guide Conrad Kain to summit the daunting North Twin Peak (), Mount Columbia, and Mount Saskatchewan () in five days. The following year, another American expedition led by William O. Field and guide Edward Feuz climbed both the North Twin Peak and the South Twin Peak () in twenty-four hours—a combined distance of about . In 1927, A. J. Ostheimer discovered a new route to the North Peak Summit, made first ascents of Stutfield Peak () and Mount Kitchener (), and became the first climber to traverse the Snow Dome () in 36 hours. During his 63-day visit to the Columbia Icefield, Ostheimer and his two companions walked over a and climbed thirty peaks—twenty-five of which were first ascents. In March 1932, three men undertook a remarkable skiing journey from Jasper to Banff that covered about . When Cliff White, Joe Weiss, and Russell Bennet reached the Columbia Icefield, they climbed to the summit of Snow Dome, and then made a downhill run descent of almost which lasted for —the longest continuous ski run in Canadian history up to that point. Their accomplishment played a major role in generating worldwide interest in the Canadian Rockies. Today, mountaineers and skiers from around the world come to the Columbia Icefield to explore some of the classic routes discovered by these early pioneers of mountaineering. Glaciers The icefield feeds six major glaciers: Athabasca Glacier Castleguard Glacier Columbia Glacier Dome Glacier Stutfield Glacier Saskatchewan Glacier Parts of the Columbia Icefield and part of other icefields and glaciers are visible from the Icefields Parkway. The icefield was first reported in 1898 by J. Norman Collie and Hermann Woolley after they had completed the first ascent of Mount Athabasca. The Athabasca River
