|Backcountry ski and snowboard mountaineering trips and equipment.|
Description: Mountaineering refers to mountain climbing. Ski and Snowboard mountaineering, also known as Alpine Touring (AT) or backcountry randonee, refers to climbing the mountain on/with skis or on/with a snowboard. By definition, this endeavor is in the backcountry, outside of the boundaries of a resort.
The equipment one uses and carries is also much different from that used within a ski resort. Avalanche beacons, probes, shovels and rescue gear are essential in unpredictable conditions. The standard ski and snowboard are hardly suitable. Mountaineering skis, bindings and boots are typically much lighter as it is you who provides the energy to fight gravity and not the ski lift. A type of snowboard known as a splitboard is used which allows the boarder to move like a skier uphill. Both mountaineering skis and splitboards use a binding which allows the foot to articulate in an nordic ski (cross country ski) fashion where the toe is allowed to pivot and the heal is permitted to move up and down to allow one to travel in a natural human walking motion.
The skis and boots used for ski mountaineering are typically lighter than their downhill alpine counterparts but still quite similar. It is the bindings which are most unique as they support two modes of operation:
Diamir Mountaineering ski bindings
Skins with angled fibers are applied to the bottom of the skis so that a forward sliding motion is enabled but a backward slide is not. The skins are removed at the top of the mountain and one travels downhill on the regular ski or snowboard base.

Duke Pros: strength, rigidity and durability for alpine downhill.
Duke Cons: One must remove boot from binding in order to change modes which release/lock heel of binding.

Black Diamond: Backcountry mountaineering ski skins
Originally ski skins were made of seal fur but are now made of nylon fabric which allow the ski to slide forward but not backward. On the other side they have a tacky surface which sticks to the ski surface but is easily removable. A metal loop fits over the point at the front of the ski so that it will not work its way aft. There is usually a clip at the rear but this seems to be optional. While the skins do allow forward travel, they are usually removed for the descent as the ski slides better without the skins attached. This system is much more effective than the old "fish scale" surface found on cross country "Nordic" skis. For extreme terrain, ski crampons are also available.
Snowboarders can hike on snowshoes (lots of work) or use a splitboard. The splitboard is a snowboard split into two halves which can act as mountaineering skis to travel up the mountain and then assemble together into a single snowboard to travel down the mountain.
Bindings reattached in cross country ski configuration
Splitboards also require skins to be attached to travel up the mountain without sliding backwards.
