Redoubt Peak is a 3,109-metre summit in the Canadian Rockies on the Alberta-British Columbia border, dividing Jasper National Park from Mount Robson Provincial Park and separating drainage to the Athabasca and Fraser rivers. Part of the steep-walled Ramparts, it was named in 1920 for its resemblance to a fortified redoubt, and the name became official in 1935. The mountain is also linked to an early climbing tragedy. F. H. Slark and F. Rutishauser made the first ascent in 1927 but died during their descent. A year later, Douglas Busk, J. E. Johnson, and guide Hans Fuhrer completed the second ascent and found traces that suggested the two men had fallen from the south face.
