Answer:
Snow in mountains means you will need shelter and a source of heat.
Travel in snow or blizzards is hazardous, on foot or by vehicle. Skiing can present dangers, either from rocks and trees, or from avalanches on steep slopes. In wilderness areas, there may also be predatory animals out in the snow. Mountain heights or bad weather can prevent normal communication, and complicate navigation. If a thaw occurs, paths and roads may be blocked or washed out by snowmelt, debris, or mudslides.
