An approach to climbing peaks in which the ascent is made in one push, usually by traveling as light as possible.
lightweight climbing that emphasizes the role of speed in taking advantage of good conditions that might prevail only a short time
a method of big wall climbing that does not involve fixed ropes; the opposite of sieging. Alpine style means climbing in a single push as opposed to fixing ropes, going to the Mountain Room bar (famous Yosemite watering hole), climbing fixed ropes up to a high point, climbing another pitch or two and returning to the Mountain Room bar, and then repeating the process.
An ultra-lightweight method of climbing in which equipment and food rations (i.e., comfort and security) are trimmed to the barest essentials in order to facilitate a swift ascent to the summit.
Alpine style refers to mountaineering in a self-sufficient manner, thereby carrying all of one's food, shelter, equipment etc. as one climbs, as opposed to expedition style (or siege style) mountaineering which involves setting up a fixed line of stocked camps on the mountain which can be accessed at ones leisure. Many consider Alpine style to be the purest form of mountaineering, setting a standard to which all mountaineers should aspire. This style became well-known and popular with Reinhold Messner, when he climbed Mount Everest without oxygen equipment in 1978, together with Peter Habeler.
