Snow skiing

Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS).

Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced as early as 600 BC in what is now China.

The word "ski" is one of a handful of words Norway has exported to the international community. It comes from the Old Norse word "skíð" which means "split piece of wood or firewood".

Asymmetrical skis were used at least in northern Finland and Sweden until the late 19th century. On one leg the skier wore a long straight non-arching ski for sliding, and on the other a shorter ski for kicking. The bottom of the short ski was either plain or covered with animal skin to aid this use, while the long ski supporting the weight of the skier was treated with animal fat in similar manner to modern ski waxing.

Early skiers used one long pole or spear. The first depiction of a skier with two ski poles dates to 1741.

Until the mid-19th century skiing was primarily used for transport, and since then has become a recreation and sport. Military ski races were held in Norway during the 18th century, and ski warfare was studied in the late 18th century. As equipment evolved and ski lifts were developed skiing evolved into two main genres during the late 19th and early 20th century, Alpine and Nordic.

Also called downhill skiing, alpine skiing typically takes place on a piste at a ski resort. It is characterized by fixed-heel bindings that attach at both the toe and the heel of the skier's boot. Because alpine equipment is somewhat difficult to walk in, ski lifts, including chairlifts, bring skiers up the slope. Backcountry skiing can be accessed by helicopter, snowcat, hiking and snowmobile. Facilities at resorts can include night skiing, après-ski, and glade skiing under the supervision of the ski patrol and the ski school. Alpine skiing branched off from the older Nordic skiing around the 1920s, when the advent of ski lifts meant that it was not necessary to walk any longer. Alpine equipment specialized to where it can only be used with the help of lifts.
