Alpine style
Alpine style is mountaineering in a self-sufficient manner, thereby carrying all of one's food, shelter and equipment 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 one's leisure. Additionally, alpine style climbing means the refusal of fixed ropes, mountain guides, high-altitude porters, supplemental oxygen and doping agents, and portable hyperbaric bags.
