Skiing



I have been doing Nordic and Alpine skiing, off and on, for about fifteen years. Due to my interest in hiking and backpacking, I wanted to do cross country skiing on hiking trails. This led me to explore alternative skiing equipment and techniques. To do backcountry skiing requires covering all types of terrain from climbing the mountain, traversing flat areas, and skiing down the mountain. 


Nordic or Cross Country (XC) Skiing

Cross country skis are long, skinny, straight without sidecut, lightweight, flexible skis, with a double camber, and without metal edges. They are extremely efficient for traversing flat or gently undulating terrain. They are very difficult to turn on even the easiest terrain. Skilled telemark skiers can make them turn. These skis are optimum for gentle uphills and flat terrain. Locomotion is via an efficient kick and glide. The double camber allows the unweighted ski to only touch the snow at the tip and tail. The center part of the ski is called the wax pocket and either contains wax or, on a no wax ski, a fish scale pattern. Either the wax or no wax pattern grips the snow under the weighted ski for kicking, while the unweighted ski glides forward.

XC skis are the most efficient way to traverse snow on foot as long as its not too deep. Three types of bindings are typically used. A three pin which is the traditional binding, a cable binding which is  preferred for backcountry use, and the New Nordic Norm (NNN) which consists of a horizontal pin molded into the toe of the boot which is then attached to the binding. All three binding styles lock the toe of the boot only, leaving the heel free to rise when touring. The foot pivots around the toe connection. Backcountry versions frequently have a cable that attaches around the back of the boot to increase the stiffness of the boot / ski connection. Touring boots are typically lightweight leather or fabric. Backcountry boots are very similar to heavy leather backpacking boots with the appropriate fixture at the toe to attach to the binding. Poles can either be fiberglass or aluminum.

Waxable XC skis provide better performance but require a commitment to learning which waxes to use, ski preparation, and possibly changing waxes during the day. In the Mid Atlantic states, no wax skis are preferred by many for their simplicity, and their relatively good performance around freezing temperatures. In my opinion, XC skis provide about 1-2% of the control of an alpine ski/boot/binding combination relative to turning the ski, particularly when going downhill. XC skiing is much easier to learn than Alpine skiing.

Ideal terrain: flat, gentle undulations, groomed trails at XC resorts, golf courses, parks, no significant downhill


Alpine or Downhill Skiing

Alpine or downhill skis are what most people are familiar with. They are single camber, heavy, torsionally stiff, metal edged skis with lots of side cut for easy turning. They are suitable only for downhill skiing, but are optimum for that type of skiing. They would be used with very high, stiff, plastic boots and a binding that locks the toe and heel in place. This provides an extremely rigid and torsionally stiff connection from the leg through the foot/boot/binding to the ski which results in excellent control of the ski in fast, steep, and icy conditions. They are extremely efficient at what they were designed to do, but not much good for anything else.

Ideal terrain: moderate to steep downhill only

Backcountry Skiing

The two ski regimes described above are the most popular and common, particularly on the East Coast. Both are very well suited to their specific ski regime. If you want to go into the backcountry, you need something else. Alpine skis/boots/bindings are useless at flat touring, and going uphill. XC skis are terrible at turning and downhill. We need a hybrid ski that does some of both. Unfortunately it will be a compromise because it's not possible to get a ski that does everything perfectly. The compromise is between turning and touring ability. A classic backcountry ski is a beefed up XC ski. It is a (usually) shorter, wider, slightly stiffer, double camber ski with metal edges, and some sidecut. Its flexibility and double camber still provide very good touring performance. The metal edges and sidecut make it somewhat easier to turn. You can ski uphill, tour the flats, and ski downhill with this ski as long as the downhill portions aren't too steep. Backcountry skis are available in wax or no wax styles.

Boots are high topped, and heavy leather - similar to backpacking boots. Bindings can be: three pin only, three pin and cable, or step in with a cable. The cable goes around the heel of the boot to increase the stiffness for turning. I really prefer the step in variety. Poles should be aluminum because of the metal edge of the skis. Fiberglass poles will break if they hit the ski edges too hard. This is probably the optimum ski for the northeast if you are doing about 70-80% touring and uphill and 20-30% downhill. I would estimate that backcountry skis/boots/bindings provide about 15-25% of the downhill and turning control of an alpine ski/boot/binding. Even though they are better than XC skis, they are still relatively hard to turn and use on the downhill portions (relative to Alpine gear). Backcountry skiing is much more difficult than alpine skiing. If your skill level is high enough, these skis will work well for most aspects of backcountry skiing.

Ideal terrain: flat, uphill, gentle to moderate downhill

Telemark Skiing

Telemark skiing is the most difficult and highest level of backcountry skiing. Some describe it as the downhill portion of XC skiing. Telemark skis are very similar to alpine skis. They are used with a touring binding that locks the toe and allows the heel to be free. You can use exactly the same binding and boot as for backcountry skiing. It's also possible to buy heavier, stiffer, plastic telemark boots which provide more control. These skis are intended for steep terrain where turning and downhill ability are more important than touring ability. They are typically what is used for backcountry skiing out west with their much steeper terrain. The steep uphill portions would be done with climbing skins on the bottom of the skis. Wax can be used for less steep uphill climbs. Telemark skis are normally not available in a waxless version. In the East, you would use them to ski steeper terrain or use at lift served ski areas.

Telemark really refers to a type of turn rather than a specific type of equipment, but most ski equipment manufacturers do make specific skis and boots for telemark skiing. This turn was invented many years ago by the inventor of XC skiing and it will work with any type of free heel ski. 

Ideal terrain: anything, flat touring performance average

Alpine Touring (AT) Skiing

Alpine touring (or Randonnee) is an attempt to short circuit the long learning curve of telemark skiing. It is attractive to people who already know how to do Alpine skiing and would like to use those skills for the downhill portion of backcountry skiing. The equipment consists of AT skis and AT boots with an AT binding that can be used in a heel lock position for downhill skiing, and a heel free position for uphill and touring. This is much more popular in Europe than here. AT skis are very similar to Alpine or Telemark skis. AT boots are multifunctional plastic boots  that can be used for Alpine skiing, Nordic skiing, backpacking, and mountaineering. The steep uphill portions would be done with climbing skins on the bottom of the skis or wax for less steep uphills. 

Ideal terrain: anything

Snowshoeing

If all else fails, go snowshoeing ! Its a lot of fun and a lot easier to learn than some of these ski techniques. Just strap them on and start walking. Get shoes that are large enough to support your weight plus backpack. Larger wood and gut or neoprene laced shoes are probably better in deep, fresh powder. The nylon reinforced neoprene is strongly preferred over natural gut for reduced maintenance. The smaller aluminum framed shoes with solid plastic decking are lighter and will provide more floatation in a smaller shoe. They would be better for backpacking where you are trying to cut weight. If you're going on somewhat steep or icy terrain you will want crampons, preferably at both the foot pivot point and the heel, and possibly along the sides. Poles help to keep your balance when traversing the side of a hill. Adjustable length poles work well for traversing hillsides on skis too.

Ideal terrain: anything that isn't too steep
