Ski touring is a form of backcountry skiing where both uphill and downhill travel are possible without needing to remove skis. Typically touring is done off-piste and outside of ski resorts, and may extend over a period of more than one day.
Ski touring cuts across both Nordic and Alpine forms and embraces such sub-disciplines as Telemark and randonnée. A defining characteristic is the skiers' heel being free to allow a natural gliding motion while traversing and ascending terrain which may range from perfectly flat to extremely steep.
Ski touring has been adopted by skiers seeking new snow, by alpinists, and by those wishing to avoid the high costs of traditional alpine skiing at resorts. Touring requires independent navigation skills and may involve route finding through potential avalanche terrain.
Ski touring has parallels with hiking and wilderness backpacking. Ski mountaineering is a form of ski touring which variously combines the sports of Telemark, Alpine, and backcountry skiing with that of mountaineering.
The history of ski touring is unwritten. Among the sport's pioneers are:
- John "Snowshoe" Thompson, perhaps the earliest modern ski mountaineer, a prolific traveler who used skis to deliver the mail at least twice a month up and over the steep eastern scarp of the Sierra Nevada to remote California mining camps and settlements. His deliveries began in 1855 and continued for at least 20 years. Thompson's route of 90 miles (140 km) took 3 days in and 48 hours back out with a pack that eventually exceeded 100 pounds of mail.
- Cecil Slingsby, one of the earliest European practitioners, who crossed the 1,550 m (5,090 ft) high Keiser Pass, Norway, on skis in 1880.
- Adolfo Kind
- Arnold Lunn
- Ottorino Mezzalama
- Patrick Vallençant
- Kilian Jornet Burgada
Ski touring requires the ability to ski off-piste, good navigation skills, and good awareness of the risks of the mountain environment in winter. In particular it requires the knowledge to assess and test snow conditions to minimise the risk of avalanche.
As the slope angles increase, the climbing ski-tourer will make switchbacks, using kick turns to change direction, typically resulting in a line that climbs at a moderate angle of 20-30 degrees. Skin tracks can be seen as zig-zags heading up a snowy mountain. Ski-tourers try to maintain the up-tracks in avalanche-safe zones as they head up the mountain, staying out from under dangerous cornices or slide paths. Setting a proper and safe skin track requires a great deal of skill and avalanche knowledge as the tourer spends most of their time climbing. Traveling quickly up potential avalanche terrain is important for safety as well. Thus physical fitness is a crucial element of safe mountain travel.
Styles of equipment
- Nordic ski touring is skiing with bindings that leave the heels free all the time. Thus, Nordic skiers do not have to change back and forth between uphill and downhill modes, which can be advantageous in rolling terrain. At the lighter, simpler end of the scale, Nordic skis may be narrow and edgeless cross-country types for groomed trails or ideal snow conditions, used with boots that resemble soft shoes or low boots.
- Backcountry Nordic: heavier than a traditional Nordic setup, but not as big and heavy as a full Telemark setup.
- Telemark: at the heavier end of the Nordic skiing equipment spectrum, for steep backcountry terrain or ski-area use.
- Alpine Touring (AT) or randonnée equipment is specifically designed for ski touring in steep terrain. A special alpine touring binding, otherwise very similar to a downhill binding, allows the heel to be raised for ease in ascending but locked down for full support when skiing downhill
- Alpine skiing equipment can be used for ski touring with the addition of a removable binding insert that allows for free heel swing on ascents.
- Climbing skins are used when either "fish scale" pattern friction aids embossed on the bottom of skis or sticky ski wax fail to provide sufficient grip for skiing uphill.
- Ski crampons (also called Harscheisen (German), couteau (French), or rampant (Italian) may be attached when conditions are particularly icy or the grade too steep for skins.
Ski Touring Regions
Ski touring can take place anywhere that has suitable snow and terrain. Some examples include
- Iceland: Activities center on the Troll Peninsula in northern Iceland.
- Norway: touring in Norway has a long tradition. Skiing was originally a practical means of winter transportation. Ski touring formed the basis of the polar expeditions of Norwegian explorers like Fridtjof Nansen and Roald Amundsen. There are thousands of kilometers of marked ski routes, both in the forested areas and the mountain areas above the tree-line. The trails are maintained by organizations like Skiforeningen in the Oslomarka area and Norwegian Trekking Association nationally including Hardangervidda, Rondane and Jotunheimen. The Norwegian Trekking Association (Norwegian: Den norske turistforening, DNT) maintains mountain trails and cabins in Norway. The association was founded in 1868. DNT has more than 200,000 members.
- The European Alps: including the Haute Route
- Canada: including Rogers Pass, Wapta, Revelstoke, Golden: in the southeast of the province at the confluence of the Columbia and Kicking Horse Rivers. Surrounded by the Rocky Mountains to the east and the Purcell Mountains and Selkirk Mountains to the west., Kananaskis Country, and Gros Morne National Park
- U.S.: touring takes place anywhere there is snow in the U.S., for example Jackson Hole,Loveland Pass, and Berthoud Pass
- Ski areas of New Zealand include Arthur's Pass National Park, Central Otago, Fiordland, Aoraki-Mount Cook National Park, Mount Ruapehu, Nelson, Ohau, Wanaka, and the Arrowsmith Range.
