|Backcountry Alpine Touring ski mountaineering trips and equipment.|
Description: Mountaineering refers to mountain climbing. Ski mountaineering, also known as Alpine Touring (AT) or backcountry randonee, refers to climbing the mountain on/with skis. 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 skis, boots and equipment 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. Alpine Touring (AT) mountaineering skis 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 known as "Walk To Ride" (WTR). For snowboarders, a type of snowboard known as a splitboard is used which allows the boarder to move like a skier uphill but then attach them together as a single snowboard for the downhill run and are covered in our article on Snowboard Mountaineering and Splitboarding.
According to Snowsports Industries of America (SIA) sales stats gathered from the ski industry, the popularity of backcountry ski touring has increased significantly. It seems obvious to me that high resort ticket prices, the quest for powder and improved equipment, have pushed people to the backcountry.
The skis and boots used for ski mountaineering are typically lighter than their downhill alpine counterparts but still quite similar. Lower weight is desired to reduce the fatigue one would experience from carrying the gear uphill.It is the bindings which are most unique as they support two modes of operation:
There are two basic designs of touring bindings available:

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.
Marker/Volkl "Kingpin" AT binding:
Salomon "Guardian" AT binding:
Touring boots are very much like traditional alpine skiing boots except that they provide the dimpled toe inserts for the pure lightweight AT pin bindings, they support more fore-aft movement in the tongue to ease the hiking of alpine accents, and are made of lighter materials.

AT boots support features for mountain ascent such as:Alpine Touring (AT) pinned boots which require a compatible binding configuration are compliant with the Touring ski-boots for adults ISO 9523 standard. These boots tilt/pivot at the toe pin of the toe binding which is pinches the toe pin recess in the toe of the boot. The alternative is to use regular downhill Alpine ski boots which are ISO 5355 compliant and use a binding where the whole frame tilts to support "Walk To Ride" (WTR) mode.
Black Diamond: Backcountry mountaineering ski skins
Skins are pre-cut to the dimension of a specific ski with angled fibers to enable the ski to slide forward more easily than backward. The skins have a tacky but easily detachable adhesive which allow the skins to stick to the bottom of the skis even with wax. Newer designs use a very smooth rubbery surface which uses suction to enhance the grip. This is an improvement in design as the skins would typically lose tackiness over time and the adhesive is typically not replaceable. The tip and tail of the skins also typically have clips which help attach the skins. 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. The skins are mounted so that a forward sliding motion is enabled but a backward slide is not.
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. While the skins do allow forward travel, they are usually removed for the descent as the ski slides better on its own base material 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 which have "teeth" which can dig into the ice to maintain traction.

Alpine Touring Locations and Guides:
Stay warm with the appropriate clothing and be safe by bringing the appropriate backcountry AT gear, avalanche gear, food and water. Training helps and hire a guide if you are unfamiliar with the area.
