Skiing is the activity of gliding over snow using skis (originally wooden planks, now usually made from fiberglass or related composites) strapped to the feet with ski bindings. Originally used primarily for transportation, skiing evolved into a popular recreational and competitive activity during the 20th century.

History

Main article: History of skiing

Although skiing probably evolved gradually from snowshoeing, Norwegian Sondre Norheim is often called the "father of modern skiing". In the 19th century, Sondre Norheim invented bindings that enabled the skier to do turns while skiing down hills. This form of skiing was called Slalom (sla låm, Norwegian dialect expression for a difficult track) by Norheim and his contemporaries. This form of skiing is now referred to as Telemark or Telemark skiing. Skiing originally was a practical activity that resembled today's Nordic, or cross-country, style. Skiing, or traveling over snow on wooden runners, has a recorded history of almost five millennia. ... A pair of modern showshoes Snowshoes, sometimes colloquially referred to as webs, are footwear for walking over snow. ...

Cross-country skiing (also known as XC skiing) is a winter sport popular in many countries with large snowfields, primarily Northern Europe and Canada. ...


The invention of firmer bindings to attach the skier's feet to the ski, likely by Austrian Matthias Zdarsky, enabled the skier to turn more effectively and led to the development of Alpine, or Downhill, skiing. Alpine skiing (or downhill skiing) is a recreational activity and sport involving sliding down snow-covered hills with long, thin skis attached to each foot. ...

Shortly thereafter, in the early 20th century, Austrian Hannes Schneider pioneered the idea of rotating the body to help steer the skis. Soon this Arlberg technique, named for his home region, spread around the world and helped make skiing a popular recreational activity.

Types of skiing

Many different types of skiing are popular, especially in colder climates, and many types of competitive skiing events are recognized by the International Olympic Committee (IOC), the International Ski Federation (FIS), and other sporting organizations. Skiing is most visible to the public during the Winter Olympic Games where it is a major sport. The International Olympic Committee is an organisation based in Lausanne, Switzerland, created by Pierre de Coubertin on June 23 1894 to reinstate the Ancient Olympic Games held in Greece between 776 BC to 396 AD.

For many people, "skiing" refers to recreational downhill skiing where one visits a ski resort, purchases a lift ticket, dons cold-weather clothing, skis, ski boots and ski poles, and embarks on a chairlift, gondola lift, or other means of mechanical uphill transport. Upon reaching the summit, the skier disembarks from the ski lift and travels downhill, propelled by gravity, usually along a marked run known as a piste. Ski routes are referred to as 'runs,' 'trails,' or 'slopes'. Most ski resorts use mechanical equipment to 'groom,' or pack down and smooth, the snow surface on certain ski trails. Grooming is normally associated with trails of lesser difficulty. Off-piste skiing includes skiing in unmarked or unpatrolled areas either within the ski resort's boundaries or in the backcountry, frequently amongst trees ("glade skiing"), usually in pursuit of fresh fallen snow, known as powder.

Skiing or snowboarding outside a ski resort's boundaries, also known as out of bounds skiing, is illegal in some ski resorts, due to the danger of avalanches on the un-patrolled areas; or the cost of search-and-rescue for lost or overdue skiers. France and Canada are some of the countries with no restrictions against off-piste skiing. In Canada, lost or overdue backcountry travellers are usually held responsible for the cost of search-and-rescue service. Backcountry skiers traveling in steep terrain prone to avalanches are encouraged to take avalanche training, travel with other experienced people, and carry special equipment for self-rescue.

Skiing technique is difficult to master, and accordingly there are ski schools that teach everything from the basics of turning and stopping safely to more advanced carving, racing, mogul or "bump" skiing and newer freestyle techniques. The venue, speed and technical difficulty associated with the sport can lead to collisions, accidents, hypothermia and other serious injury or illness, including death. Regional Ski Patrol organizations, such as the National Ski Patrol in the U.S., exist as a voluntary organization to provide guidance, help, medical assistance and emergency rescue to those in need of it.

Many non-skiers wonder why skiers are willing to risk such injury. Skiers have a variety of answers to this question, but a common explanation is that it simply feels good, rather like flying, and that, when done carefully, poses no greater risk of injury compared to other sports. Of course, there is some aspect of danger, but that is part of the appeal. Skiing is the fastest means of land transport possible without mechanical assistance other than skis. Many skiers have had experiences where they have achieved a union of the mind and the body by practising this sport; where the mind trusts the body to perform in an exceptional manner and the body trusts the mind not to lead it off an un-navigable cliff.

In addition to their role in recreation and sport, skiing is also used as a means of transport by the military, and many armies train troops for ski warfare. Ski troops played a key role in retaining Finnish independence from Russia during the Winter War, and from Germany during the Lapland War, although the use of ski troops was recorded by the Danish historian Saxo Grammaticus in the 13th century. The sport of Biathlon was developed from military skiing patrols. A troop is a military unit, originally a small force of cavalry, subordinate to a squadron and headed by the troop leader. ...

Skiing for people with disabilities

Downhill skiing for people with disabilities is a recreational pastime open to those with any manner of cognitive and/or physical disabilities. Adaptations include the use of outriggers, ski tip retention devices, ski sliders, sit skis (dual and mono), brightly colored guide bibs, ski guides, and inter-skier communication systems. Recreational skiing programs for people with disabilities exist at mountains across the globe. In the Northeastern part of the United States, Maine Handicapped Skiing is one of the largest, operating out of the Sunday River ski resort. In the western part of the United States, the National Sports Center for the Disabled at Winter Park Resort near Denver, Colorado attracts world-class disabled athletes from Europe, Asia, and North America. Currently the International Ski Federation (FIS) sanctions a number of regional, national, and international disabled skiing events.

The term "ski bum" has been used to classify skiers who want to spend the entire skiing season at the resort, engaging in their favorite sport and obtaining simple jobs, mainly in the local tourism industry to make a living; in reality, however, many different types of people engage in skiing. Some people take days off of work occasionally, go after work, after school, or on the weekends, for short trips if the ski resort is near their home. Recently, skiers and snowboarders have engaged in rivalry on and off the slopes, which is usually friendly and increases the notoriety of both sports; snowboarders often share hills with downhill skiers.

There is no governing body that assigns difficulty ratings to ski trails. Instead, resorts assign ratings to their own trails, marking a given trail according to its relative difficulty when compared with other trails at that resort. As a result, identically-pitched trails at different resorts can have different ratings.


Although slope angle is the primary consideration in assigning a trail rating, other factors come into play - including trail width, normal snow conditions and whether or not the resort normally grooms the trail.


The ratings are as follows:

  • Green circle: A green circle is used to indicate the easiest pistes at a mountain. Green circles are generally wide and groomed, and, although there is no standard, typically have slope angles ranging from 6% to 25%. A green circle indicates that the trail is 'easier' compared to other trails at the resort. As a result, these trails are typically the most popular trails among newer skiers and snowboarders. Skiers and snowboarders sometimes refer to green circle runs as "beginner trails."
  • Blue square: Often called an "intermediate slope," trails marked with a blue square are more difficult than those with a green circle. The slope angle of Blue squares commonly range from 25% to 40% and are usually groomed. Blue runs comprise the bulk of pistes at most ski areas, and are usually among the most heavily trafficked.
  • Black diamond: A black diamond indicates that a trail is among the most difficult at a given mountain. Black diamond trails are steep (often 40% and up) and may or may not be groomed, though the introduction of winch cats has made the grooming of steep slopes both possible and more frequent.
  • Double black diamond: Until the 1980s, by convention, North American ski resorts limited trail ratings to green circle/blue square/black diamond. But technological improvements in trail construction and maintenance, coupled with intense marketing competition, led to the creation of a new trail rating symbol: the double black diamond. Many North American resorts now use the double-black symbol, although some retain the old three-symbol system. In general, trails marked with a double black diamond are even more challenging than those marked with a single diamond. Usually, this is due to significantly increased slope angle, but other factors such as width, exposure, and the presence or proximity of obstacles such as steep dropoffs, trees or other potential hazards may result in a double-diamond rating. Although the double black diamond is subject to the same lack of standardization as the other three symbols, trails marked with double black diamonds should typically be attempted only by very skilled and experienced skiers and snowboarders.
  • Variations: Although the North American trail rating system is a convention used by most resorts, some ski areas have unilaterally made modifications to the system by using combinations of symbols. For example, you might see a trail rating with both a blue square and a black diamond at a given resort, indicating that the trail is more challenging than other blue square runs at the resort but less challenging than the black diamonds. Similarly, two green circles, indicate a trail that is more difficult than a single circle, but less difficult than a blue. Two blue square's also indicate that a trail is more difficult than a single blue, but not as difficult as a black diamond. Several ski areas have also designated trails with a triple black diamond. Most resorts, however, resist this type of symbol proliferation to avoid confusing their customers.
  • Terrain Parks: Terrain parks are small parts of trails, or sometimes their own, that have a variation of jumps, halfpipes, and other "extreme" sporting obstacles. The trails are represented by an orange horizontal oval-like shape. Usually, if you want to know how challenging the terrain park will be, notice what level trail it is on. If it is on a diamond or a double diamond, you can deduct that the obstacles will be more challenging than then others in places where the level is a square.

Because of the lack of standardization in trail ratings, it's generally a good idea to start on a given resort's less challenging runs, as indicated by their trail ratings, to develop a sense of how difficult that resort's terrain actually is before moving on to more demanding terrain.


Europe

In Europe, pistes or slopes are classified by a similar, colour-coded system, although shapes are not used (all ratings are circles). The ratings are:

  • Green: Learning or 'baby' slopes. These are usually not marked trails, but tend to be large open, gently sloping areas at the base of the ski area.
  • Blue: An easy trail, similar to the North American Green Circle, and are almost always groomed, or on so shallow a slope as not to need it.
  • Red: An intermediate slope. Steeper, or narrower than a blue slope, these are usually groomed, unless the narrowness of the trail prohibits it.
  • Black: An expert slope. Steep, may or may not be groomed, or may be groomed for mogul. It is worth noting that 'Black' can be a very wide classification, ranging from a slope marginally more difficult than a 'Red' to very steep avalanche chutes like the infamous Couloirs of Courchevel.
  • Yellow: In recent years, many resorts reclassified some black slopes to yellow slopes. This signifies a skiroute, an ungroomed and unpatrolled slope which is actually off-piste skiing in a marked area. Famous examples are the Stockhorn area in Zermatt and the Tortin slopes in Verbier.

Courchevel is the name of a ski area located in the Savoie region of the French Alps, and part of Les Trois Vallées, the largest linked ski area in the world. ... In June, the Matterhorn is still snow-covered, while it is spring in Zermatt below. ... Verbier is a ski resort in the Swiss Alps, in the canton of Valais. ...

Japan

Japan uses a color-coded system, but shapes do not usually accompany them. Some resorts, mainly those catering to foreigners, use the North American or European color-coding system, adding to the confusion. When in doubt, check the map legend. The usual ratings are:

  • Green: Beginner slopes. These are usually near the base of the mountain, although some follow switchback routes down from the top.
  • Red: Intermediate slopes. At most ski areas in Japan, these constitute the majority of the slopes (40% to 60%, depending on how the slopes are accounted).
  • Black: Expert slopes. These are the steepest and most difficult slopes at the ski area. The difficulty of these compared to like-classified slopes at other ski areas is heavily dependent on the target audience.

Japan has more than 600 ski areas (108 in Nagano Prefecture alone), many of them small and family-oriented, so comparisons between the three slope classifications in Japan and "equivalent" slopes in Europe or North America should be taken with a grain of salt. Nagano Prefecture (長野県; Nagano-ken) is located on Honshu island, Japan. ...


Snow and weather

Skiers and snowboarders can encounter a wide range of snow and weather conditions, in part due to the location of specific resorts and global weather patterns at the time.


Natural snow ranges in consistency from very light and fluffy to dense and heavy, depending upon atmospheric conditions as it falls. Snow is often measured by moisture content, or the amount of water in a given volume of snow. Some areas of the United States' Rocky Mountains, for example, can receive considerable amounts of snow with a moisture content as low as three to five percent; in the Northeastern United States and the Alps, moisture content is more typically 15 percent or more. Snow made by mechanical snowmaking often has moisture content of 35 percent or more. Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes. ... Snow cannon at Mölltaler Gletscher, Austria A snow cannon is a device used to produce snow artificially. ...


Temperatures play a critical role in snow moisture content, but other atmospheric conditions are also relevant. Air currents and other factors determine snow crystal shape; obviously, the farther apart given snow crystals are, the more air is contained in the newly settled snow, resulting in lower net moisture content in a given volume of snow. Snow produced mechanically typically has high relative moisture content and low amounts of loft because the crystal structure resembles small, dense pellets.


Even the fluffiest snow has mass, and snow typically settles under its own weight after time. This is one reason why untouched snow measuring 20 cm on the day it falls might be measured at 15 cm the day following. Snow is also subject to sublimation - a process by which water can go directly from a frozen state to a gaseous state without first melting. It's the same process that ultimately makes ice cubes shrink in your freezer. Sublimation of an element or substance is a conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. ...


There are other factors that impact snow beyond its moisture content and crystal shape, however. Snow is impacted by wind, sunlight, skier traffic, ambient air temperature, relative humidity and grooming equipment; all of these factors combine to change snow crystal shape and density over time.


Thus, skiers and snowboarders typically encounter a wide range of snow conditions over the course of a season. Some of the more common conditions include:

  • Powder: Light, fluffy snow, found during and immediately after a snowstorm. Skiing and snowboarding in deep powder snow is a favorite among skilled, experienced skiers and snowboarders; sometimes know as powderhounds.
  • Packed Powder: Packed Powder is powder snow that has been compressed, either by means of mechanical snow grooming apparatus or skier traffic. The term can also be used to describe snow that has been properly made with adequate control over snowmaking apparatus. This snow condition is favored by beginners and the majority of recreational skiers, in that it tends to be relatively forgiving, easy to turn upon, and requires less skill to negotiate than powder snow.
  • Granular snow: Granular snow crystals are small pellets. Depending on sun and temperature conditions, it may be wet granular snow - meaning that there is a considerable amount of unfrozen water in it, or loose granular snow, which has no unfrozen water. Wet granular snow will form a snowball; loose granular snow will not. Wet granular conditions are often found in the springtime. Loose granular conditions are generally produced when wet granular snow has re-frozen and then been broken up by snowgrooming apparatus.
  • Corn snow: Corn snow is the result of repeated daily thaws and nightly re-freezing of the surface. Because of the thaw-refreeze cycle, snow crystal shapes change over time, producing crystal shapes somewhat akin to wet granular, but larger. True corn snow is a delight to ski or ride.
  • Ice: skiers and snowboarders typically regard any snow condition that is very hard as 'ice.' In fact, true ice conditions are comparatively rare. Much of what is perceived to be ice is actually a frozen granular condition - wet granular snow that has refrozen to form a very dense surface. Telling the difference is comparatively easy; if one can get a ski pole to stand up in it, the surface is likely to be more of a frozen granular surface than an icy one - and while it's certainly not as enjoyable as many other snow conditions, skilled skiers and snowboarders can successfully negotiate it. In fact, it's a preferred condition among racers, in that the surface tends to be quite fast and race course conditions tend to remain more consistent during the race, with fewer ruts developing on the course. Another form of icy condition can be found at higher elevation resorts in the Rocky Mountains and in Europe; direct sunlight can melt the top layers of snow crystals and subsequent freezing and produce a very shiny, slick surface.
  • Crust: Crusts are extremely challenging conditions. A crust condition exists when soft snow is covered by a harder upper layer upon the surface. This crust can be created by freezing rain (precipitation formed in warmer upper levels of the atmosphere, falling into a temperature inversion at which surface temperatures are below freezing, and freezing on contact with the ground), by direct sunlight, and by wind loading which packs down the upper layers of the snowpack but leaves lower layers more or less unaffected.
  • Spring Conditions: a catch-all term ski areas use to describe conditions when numerous different surface types can be found on the mountain - usually in the later part of the season, although the term is sometimes used during an extended midwinter thaw. The term also generally reflects the presence of bare spots and/or areas of thin cover. With spring conditions, the snow is usually firm in early morning (even reaching frozen granular status if left ungroomed), breaking a softer corn or wet granular surface mid-day, and is often very soft and mushy in afternoon (many skiers refer to this type of snow condition as 'mashed potatoes," due to its heaviness). The speed with which conditions change on a given spring day is directly related to the exposure of the slope relative to the sun.
