Alpinism is the ascent to high peaks via unprotected, unmarked routes.
Winter alpinism includes climbing snow-ice and mixed routes, ice climbing, alpine skiing, and snowboarding.
Partially included are also backcountry skiing and approaches to peaks in winter.
For such exploits, appropriate mountaineering equipment is essential; therefore, items like ice axes, crampons, snowshoes, shovels, and safety ropes are usually a must.
Safety first!
Many, even experienced mountaineers, have lost their lives in the heart of the mountains.
The greatest danger in winter comes from avalanches, which are most common after fresh snowfall. Weather is generally one of the factors that mountaineers always consider before heading into the mountains.
