Alpine style
Alpine style, or informal variations of it, is the most common form of mountaineering today. It involves a single, straightforward climb of the mountain, with no backtracking. This style is most suited for medium-sized mountain areas close to civilization with elevations of , such as the Alps or the Rocky Mountains. Alpine style ascents have been done throughout history on extreme altitude (above 5,000 m) peaks also, albeit in lower volume to expedition style ascents. Climbers generally carry their loads between camps without backtracking, in a single push for the summit. If the summit is reachable from the base camp or trailhead within one day, then alpine-style mountaineers will not change camps at all, and only carry the slightest of loads (necessary nourishment and equipment) up to the summit. "Light and fast" is the mantra of the alpine mountaineer.
