Styles of mountaineering

There are two main styles of mountaineering: Expedition style and Alpine style.

A mountaineer who adopts Alpine style is referred to as an Alpine Mountaineer. Alpine Mountaineers are typically found climbing in medium-sized glaciated mountain areas such as the Alps or Rocky Mountains. Medium-sized generally refers to altitudes in the intermediate altitude (7,000' to 12,000') and first half of high altitude (12,000' to 18,000') ranges. However, alpine style ascents have been done throughout history on extreme altitude (18,000' to 29,000') peaks also, albeit in lower volume to expedition style ascents. Alpine style refers to a particular style of mountain climbing that involves a mixture of snow climbing, ice climbing, rock climbing, and glacier travel, where climbers generally single carry their loads between camps, in a single push for the summit. Light and fast is the mantra of the Alpine Mountaineer.

The term alpine style contrasts with expedition style (as commonly undertaken in the Himalayan region or other large ranges of the world), which could be viewed as slow and heavy, where climbers may use porters, pack animals, glacier airplanes, cooks, multiple carries between camps, usage of fixed lines etc. A mountaineer who adopts this style of climbing is referred to as an Expedition Mountaineer. Expedition mountaineers still employ the skill sets of the alpine mountaineer, except they have to deal with expanded time scale, more severe weather exposure, and additional skills unique to expeditionary climbing. The prevalence of expedition style climbing in the Himalaya is largely a function of the nature of the mountains in the region. Because Himalayan base camps can take days or weeks to trek to, and Himalayan mountains can take weeks or perhaps even months to climb, a large number of personnel and amount of supplies may be helpful. This is why expedition style climbing is frequently used on large and isolated peaks in the Himalaya. In Europe and North America there is less of a need for expedition style climbing on most medium-sized mountains. These mountains can often be easily accessed by car or air, are at a lower altitude and can be climbed in a shorter time scale. Expedition style mountaineering can be found in the larger high altitude and extreme altitude North American ranges such as the Alaska Range and Saint Elias Mountains. These remote mountaineering destinations can require up to a 2-week trek by foot, just to make it to base camp. Most expeditions in these regions choose a glacier flight to basecamp. Route length in days from basecamp can vary in these regions, typically from 10 days to 1 month during the climbing season. Winter mountaineering on major peaks in these ranges can generally consume between 30 to 60 days depending on the route, and can generally only be tackled via expedition style mountaineering during this season.

The differences between, and advantages and disadvantages of, the two kinds of climbing are as follows:
Expedition style

uses multiple trips between camps to carry supplies up to higher camps
group sizes are often larger than alpine style climbs because more supplies are carried between camps

fixed lines are often used to minimize the danger involved in continually moving between camps
   
supplemental oxygen is frequently used
   
higher margin of safety in relation to equipment, food, time, and ability to wait out storms at high camps
   
avoidance of being trapped in storms at high altitudes and being forced to descend in treacherous avalanche conditions
   
possible higher exposure to objective hazards such as avalanches or rockfall, due to slower travel times between camps
   
higher capital expenditures
   
longer time scale

Alpine style

   
climbers only climb the route once because they do not continually climb up and down between camps with supplies
   
fewer supplies are used on the climb therefore fewer personnel are needed
   
alpine style ascents do not leave the climber exposed to objective hazards as long as an expedition style climb does; however, because of the speed of the ascent relative to an expedition style climb there is less time for acclimatization
   
supplemental oxygen is not used
   
danger of being trapped at high altitude due to storms, potentially being exposed to HAPE or HACE
   
lower capital expenditures
   
shorter time scale

Mountaineering has become a popular sport throughout the world. In Europe the sport largely originated in the Alps, and is still immensely popular there. Other notable mountain ranges frequented by climbers include the Caucasus, the Pyrenees, Rila mountains, the Tatra Mountains and the rest of the Carpathian Mountains, as well the Sudetes. In North America climbers frequent the Rocky Mountains, the Sierra Nevada of California, the Cascades of the Pacific Northwest, the high peaks of The Alaska Range and Saint Elias Mountains.

There has been a long tradition of climbers going on expeditions to the Greater Ranges, a term generally used for the Andes and the high peaks of Asia including the Himalayas, Karakoram, Hindu Kush, Pamir Mountains, Tien Shan and Kunlun Mountains. In the past this was often on exploratory trips or to make first ascents. With the advent of cheaper, long-haul air travel, mountaineering holidays in the Greater Ranges are now undertaken much more frequently and ascents of even Everest and Vinson Massif (the highest mountain in Antarctica) are offered as a "package holiday".

Other mountaineering areas of interest include the Southern Alps of New Zealand, the Coast Mountains of British Columbia, the Scottish Highlands, and the mountains of Scandinavia, especially Norway.
