It's snowing
When in a group of snow fields, it is best to go goose bumps, close to each other; then no one gets lost in a snowstorm, and in the event of an accident, you can help quickly. He is often, that a thin layer of ice is covered with snow; you have to tread very carefully, you can lean on an ice ax.

Steep slopes and icefalls
Trees, Snow-covered slopes and icefalls must be traveled very carefully. Climbing equipment and appropriate skills are often required. You have to tie a rope with your partners and belay along the way. While negotiating an obstacle, you can help yourself with an ax; it is also used to inhibit skidding or belay. Never walk on ice covering water bodies. Even if there is no water under the ice layer, a layer of air of several meters remained there. If you lose your balance and fall on a slope covered with snow or ice, stick your pickaxe in them, this will reduce the slip rate.

CROSS COUNTRY SKIING
Cross country skis are long and narrow. Their slides are covered with grease, which allows both going downhill, as well as skipping step, without sliding downhill. Movement is done by pushing back with the rear ski and extending the front ski; besides that, there are other steps in cross-country skiing. This way of moving allows you to go deep, fresh snow, on which normal walking would be impossible.

Noiseless glides
Cross-country skiing is a way to quickly and quietly travel through the wild, snow-covered areas, often inaccessible to walkers.
