Ski Touring - Techniques

Techniques

Going uphill or across a flat also requires grip, so that the ski will glide forward but not slide backwards when weighted. Dedicated cross-country touring skis may have a fish-scale pattern engraved into the base of the ski to enable the ski to grip, but most types of ski require the use of sticky wax or climbing skins for their smooth surface to grip. Skins are removable pieces of nylon fabric whose nap runs at an oblique angle, allowing the ski to glide forward, but not back. Originally, these skins were actually made of furry seal skin.

If the snow is particularly icy or the skin track very steep, then the ski tourer may choose to attach ski crampons, sometimes called Harscheisen (German), couteau (French), or ramponi (Italian). Crampons are like knives that cut deeper into the snow.

As the slope angles increase, the climbing ski-tourer will make switchbacks, using so-called "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 the hill is important for safety as well. Thus physical fitness is one of the most important elements of safe mountain travel in potential avalanche terrain.

On reaching the summit or other intermediate destination, skins (if used) are removed and the skiers prepare to descend. In traditional cross-country skiing equipment and more robust telemark equipment, the skier's heel is also free on the descent, while AT skiers lock down their heels for the descent in typical alpine skiing style.

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. Avalanche rescue equipment including radio transceiver, probe and shovel should be carried, and the ability to use them quickly and efficiently is required.

Additionally, ski mountaineering implies climbing a mountain with the intent of skiing it, often from the summit and/or down an elegant "line." Ski mountaineering blurs the line between mountaineering and skiing, as advocates typically choose peaks that are both worthy climbs and challenging descents. Ski mountaineering may require kicking in steps up steep sections while carrying the skis on a backpack. Ski mountaineers may also use ropes, ice axes and crampons for ascending slopes too steep for skinning or kicking steps. In some areas, ski mountaineering involves glacier travel, a whole subject unto itself. When skiing on glaciers it is wise for the party to wear harnesses, carry crevasse-rescue gear, and sometimes rope together to allow crevasse rescue techniques to be employed.
