The snow slope must not only pay attention to cracks, but also be careful not to collapse the snow. In places where ice and snow meet the slopes of snow-covered hills, snow is often deep and must be grouped when the action takes place. When passing through the snow bridge, the open-ended explored the snow bridge and made it through. If the snow is soft and you have to pass it, you should go ahead. When climbing a steep slope, be sure to stand on both feet before moving. To step forward, use the forefoot of your feet to step on the snow and step on the steps to move the rear feet. If you accidentally slip, you should immediately lie down and prevent it from falling.
If you climb a glacier and snow slope, you have to take a few cracks. In the snow, go up and pick the place where the snow is hard. Go hot, do not quench your thirst with ice and snow, suddenly devour ice and snow, easy to get throat inflammation. In fact, when the thirst is deteriorating, it can be melted with ice and sip. Try not to swallow it. The water will increase the burden on the body's circulatory organs and affect physical strength. When walking on soft snow for a long time, stride and shorten the time to walk in the snow. When you walk, you have to step back a little and then step up and step forward. Feet retreat is to make snow shoes before there is room for movement, when you take a step forward, you can also play a role in snow. To take a steep slope, use the slope of the inner edge of the snowshoe to avoid the body from reaching the outer edge. When the snow freezes very hard, take off the snow shoes and walk.
Travelling in the valley should be near the centerline of the valley to avoid rolling hillsides. Do not get close to snowballs, and do not walk under snowballs to avoid triggering an avalanche.
Snow sled, stretch to the ridgeline or cliff downwind. When the windward slope is slow, it is easy to form snowballs, and steep slopes around 45 degrees are not easily formed. In areas where the wind direction is indefinite and the slopes on the sides of the ridges are different, special attention is paid. Alpine action, avalanche is a huge disaster. In May 1957, Ding Xingyou, the first mountaineering martyr in New China, died of an avalanche in Gongga Mountain. In January 1991, the 17-member Sino-Switzerland united mountaineering met with avalanche between the Nu River and the Lancang River in northwestern Yunnan and was completely destroyed.
Avalanches are induced by acoustics, vibrations, rolling rocks or snow, and the effects of wind. Avalanches usually occur in slopes with small snowballs rolling down, slopes with cracks in snow, slopes with snow slopes of 36 to 42 degrees without trees, long slopes, convex slopes, slopes in the south and southwest, In order to cover the new snow above the old snow and soft snow and other places due to rising temperatures. Generally speaking, it is sunny after snow and snow avalanches occur at 9 to 10 o'clock in the morning. Abandoned by the risk of avalanche should pay attention to: pre-release the straps, in order to relieve the large backpack and other equipment, if necessary, to protect the freedom of movement. Remove blizzards that impair vision and hearing, and discover signs of avalanches as early as possible. Avoid crossing dangerously snowy slopes. Avoid shooting and other acoustic vibrations. Avoid falling and other impacts on the snow surface.
If you are involved in an avalanche, you should repeatedly do swimming in the moving snow stream and strive to float on the surface of the snow stream. Because the hands and feet are difficult to move after the avalanche stops, the snow surface should be floated as much as possible during the snow flow. When buried in the snow, let the saliva in your mouth flow out, look at the direction of the flow, determine if you are upside down, and then try to save yourself.

Climbing glaciers and snow slopes requires special care. There are many cracks on the glaciers, and the greatest threat to humans is the icefall area and cracks on the edge of the foothills, especially the hidden cracks covered by snow. When passing through a fissure, several people should act in groups and connect each other with a rope. The distance between two adjacent people is 10 to 12 meters. People who have opened the way in front of them must constantly detect the actual situation. The person behind must walk on the footprints of the person in front, so it is safer. When you pass through the ice bridge on the cracks, you must move forward.
