Ski mountaineering

There are many who find in the combination of skiing and mountaineering the finest of all sports, for whom no ski tour is perfect unless it includes the ascent of some big peak, or traverse of some great glacier pass, and also yields the ski-runner the unfettered joy of a perfect unhampered run down some great glacier. It is not merely skiing; it is not merely scenery that draws us to the glaciers on skis. It is rather the knowledge that the skiing motion seems to lend a new significance to mountain beauty, so that the impressions gained in some run down a glacier highway are deeper, more vivid and more enduring than those which reward the man on foot.
