The rules of behavior in the mountain were dictated by the International Ski Federation (ISF), an association created in 1924. Said rules should be followed by any person on the snow of any ski resort.
Respect others: the skier (or snowboarder) should not risk or cause damage to others.

Control speed and behavior: The skier (or snowboarder) should ski in a controlled manner. His/her ski speed and manner of skiing (or snowboarding) should adapt to his personal ability, general land conditions, snow, and weather and traffic density in the trails.

Chose the route: the skier (or snowboarder) who is ahead has priority above the one who comes at the back.


Overtaking: the overtake can be made on either side above or below, on the right or on the left but always in such a manner as to leave enough space to prevent the advanced skiers (or snowboarders) voluntary or involuntary evolutions.

Enter into a slope, starting gliding across and turning upwards: every skier (or snowboarder) who enters into a slope, restarts his/her way after stopping or evolves upwards, should look upwards and downwards the slope to ensure that he/she will not cause danger.

Stopping in the slope: every skier (or snowboarder) should avoid stopping in the middle of the slope, in narrow pass or with no visibility. In case of fall in one of these places, the skier (or snowboarder) should move to one side and leave the slope free as soon as possible.

Go up and down the slope on foot: the skier (or snowboarder) who goes up or down on foot should do it on the slope edge.

Respect the signals: every skier (or snowboarder) should respect the signal lighting and signaling.

Offer help: In case of accident, every skier (or snowboarder) should offer help.

Identify oneself: Every skier (or snowboarder) who has watched an accident, being or not responsible of such accident, should identify and exchange names and addresses.
The origin of the term ski is Norwegian (skidh) which means board, referring to the material which the first skis were made. The origins of the white sport are so remote as man himself, but with the passage of time, certain names where established for the different disciplines:

Andean (or Alpine) Skiing

Is the one practiced by most amateurs and is practiced in oppressed snow trails and in off-piste areas. At the moment of competing, there are five testing: slalom, giant slalom, descent, combined and super giant.


Carving (o parabolic)

It constitutes and evolution of the traditional Andean skis. The carving skis are shorter than traditional ones, which offer a better easiness to turn on the edges.

Cross-country Skiing (or High Mountain)

This discipline consists of a combination between Alpinism and Andean ski. The difference from traditional ski is that you always ski in different isolated places of virgin snow. Su prctica requiere saber esquiar bien sobre pistas y lo mejor es hacer esta clase de excursiones en grupo.

Freestyle Skiing

It can be practiced with conventional skis or with skis specially designed for this discipline. What attracts most in Freestyle skiing is the freedom of expression that each skier reaches when practicing it. Some ski resorts have parks for the practice of acrobatics.

Extreme Skiing

Though it is simple to learn, its practice is quite risky, as it consists of going downhill with obstacles in off-piste and non-patrolled areas. You not only need to know to ski very well but also on every type of snow and first- aid.

Nordic Skiing (or cross-country skiing)

SIt appeared in Nordic countries due to a transport and communication need. It is like a walk but on skis, almost as skating. As opposed to Alpine ski, the boots are flexible and the heel of the boot cannot be fixed to the ski.

Snowboard

Those who practice snowboard, look for vertigo while descending on the powder snow, deep snow and off-piste. It is practiced in every ski resort but the most advisable are those in the province of Neuqun. There are at least three different styles: freestyle, freeride and Alpine. While freestyle is the favorite style for those who like jumping and what is ideal is to practice is in a Snow-Park, freeride is practiced in virgin areas where there are no charts and no ski lifts. Finally, Alpine style is practiced with a narrower board which enables quick descents on groomed or hard snow.

Classifying snow is a less scientific task than sensorial. There are elements born in mind at the moment of naming the different types of snow, such as weather, snow accumulation on the slope, the passage of time since the moment it snowed, the grounds and footprints. Below there some of these type of snow:
Powder Snow: is the snow which falls dry and, once accumulated on the ground, continues dry. It flies away with wind. It is the best snow to ski, as it enables skier to glide across easily.

Humid Snow: is the snow which, when accumulating on the ground, has a high water percentage. It originates in rains or due to the fall of wintry mix (rain and snow mixed) on snow that has already accumulated. Often it complicates the skier movements, as it sticks to the ski base due to its dense solidity.

Marble Snow:is a mixture of accumulated snow, humid snow and some ice. Gliding across turns quite difficult for the skier, as it is humid and brakes the movements.
Deep Snow: is the snow accumulated in great amounts without being groomed. Usually you find deep snow in off-piste areas.

Hard Snow: is the groomed or iced snow. It is almost impossible skiing on this type of snow.

Groomed Snow: is the snow which has been compacted on the slope.

Virgin Snow: is that snow that hasnt been groomed yet, it has no tracks

Wintry Mix (Rain and Snow Mixed): is the snow that cannot solidify completely.

Spring Snow:is the kind of snow formed when high temperatures melt the snow. It is not so good as powder snow but it is also the skiers allied. It appears at the beginning of September, this is the reason why it has this name.

Carton Snow:it consists of various accumulated layers of snow and ice. It is not a good snow to glide across.

Salt Snow: it is the frozen snow just as hail which, once fallen, it looks like scattered salt grains.

Milling Snow: is the groomed snow that has already been compacted, which makes it more solid.

Artificial Snow: is the snow that is produced by the snowgun.
The difference between a slope and a path is that the first is sufficiently wide so that the skier establishes circuits within the space comprised by the trail. In order to interpret a trail map there are certain references at the bottom of the page in each map. Such references may set forth the slope degree in each trail, or indicate the difficulty in each length by means of colors or shapes.
There is an international convention which sets forth a correspondence of colors and difficulty degree of each trail. This is:

Green Slopes: Beginner Level

Blue Slopes: Advanced Beginner Level Intermediate Level

Red slopes: Intermediate Level Expert Level

Black slopes: Expert Level

Dotted Black Slopes (off-piste): Expert Level

These indications, apart from appearing in the trail maps, can be found at the beginning of each trail, in order to help the skier. There are ski resorts who also design their own signaling.
The slopes in the trails are measured in degrees, calculating such as if they were the side of a triangle. According to the difficulty level of the trail, a certain amount of degrees correspond to such trail

Green trails:slopes under 15

Blue trails: slopes up to 25

Red trails: slopes no greater than 45

Black trails: slopes of 45 or more.

Classification is based on the general difficulty may have in the way.
