which involves proceeding on steep sections of blank ice with crampons and ice axes. This activity often requires progressing on steep and blank sections of ice. Most mountaineers have to rely on ice climbing skills to climb upon the higher peaks in the European Alps, Himalayas and Canadian ranges.
Rules and governance
Mountaineering lacks formal rules – though appropriately empowered bodies make many pertaining to specific use of mountains and practices on them. In theory, any person may climb a mountain and call themself a mountaineer. In practice, the sport is defined by the safe and necessary use of technical skills in mountainous terrain: in particular, roped climbing and snow travel abilities. A variety of techniques have been developed to help people climb mountains that are widely applied among practitioners of the sport.
Despite its lack of defined rules and non-competitive nature, certain aspects of mountaineering have much of the trappings of an organized sport, with recognition of specific climbing activities – including

Terrain and techniques

Mountaineering techniques vary greatly depending on location, season, terrain, and route. Both techniques and hazards vary by terrain, spanning trails, rock, snow, and ice. Mountaineers must possess adequate food, water, information, equipment, stamina, and skill to complete their tasks.
Walk-up terrain
The term "walk-up" or "trek" is used to describe terrain in which no technical equipment is needed.
To traverse this terrain, mountaineers
hike long distances to a base camp or the beginning of rough terrain, either following trails or using navigation techniques to travel cross-country. Hiking may be a strenuous activity, and adequate

involves technical skills including the ability to place anchors into the rock to safely ascend a mountain. In some cases, climbers may have to climb multiple
pitches of rock to reach the top. Typically, for any one pitch, there is a
belayer who is stationary and creates tension on the rope to catch a climber should he or she fall, and a climber who ascends the rock. The first climber, called the ''leader'', will reach a point on the rock and then build an
anchor

Once anchored, the leader will then belay the climber coming up from below. Once the follower reaches the leader, the leader will often transfer all necessary protection devices (known as a rack) to the follower. The follower then becomes the leader and will ascend the next pitch. This process will continue until the climbers either reach the top, or run into different terrain.
For extremely vertical rocks, or to overcome certain logistical challenges, climbers may use

techniques. This involves the use of equipment, such as ladders,
fixed lines, and
ascenders to help the climber push themself up the rock.
In alpine climbing, it is common for climbers to see routes of mixed terrain. This means climbers may need to move efficiently from climbing glacier, to rock, to ice, back and forth in a number of variations.

s, which are simply carved out of consolidated snow or ice, also sometimes serve as anchors. Alternatively, a roped team may choose not to use anchors; instead, all members of the team will prepare to use their ice axes to self-arrest in the event should a team member fall.
It is not always wise for climbers to form a rope team, since one falling climber may pull the entire team off the mountain. However, the risks of individual, unprotected travel are often so great that groups have no choice but to form a rope team.

or mixed climbing. Specialized tools such as
ice screws and
ice picks help climbers build anchors and move up the ice, as well as traditional rock climbing equipment for anchoring in mixed terrain. Often, mountaineers climbing steep snow or mixed snowy rock terrain will not use a fixed belay. Instead, each climber on the team will climb at the same time while attached to anchors, in groups of two. This allows for safety should the entire team be taken off their feet which also allows for greater speed than the traditional technique of belaying one climber at a time. This technique is known as ''simul-climbing'' or a ''running belay'' and is sometimes also used on ice, however, the risk of dropping frequently displaced ice on the lower team member(s) limits its usefulness on ice. Traditional belays are also used; in this case, this is sometimes necessary due to ice fall hazard, steepness, or other factors.
Shelter
Climbers use a few different forms of shelter depending on the situation and conditions; alpine shelters or arctic shelters. Shelter is a very important aspect of safety for the climber as weather in the mountains may be very unpredictable. Tall mountains may require many days of camping.
Short trips lasting less than a day generally do not require shelter, although for safety, most mountaineers will carry an emergency shelter, such as a light

s. The ability of these shelters to provide protection from the elements is dependent on their design. Mountaineers who climb in areas with cold weather or snow and ice will use more heavy-duty shelters than those who climb in more forgiving environments.
In remote locations, mountaineers will set up a "base camp", which is an area used for staging attempts at nearby summits. Base camps are positioned to be relatively safe from harsh terrain and weather. Where the summit cannot be reached from base camp in a single day, a mountain will have additional camps above base camp. For popular mountains, base camps may be at a fixed location and become famous. The
Everest base camps and
Camp Muir are among the most famous base camps.
Hut

Camping is not always an option, or may not be suitable if a mountain is close to civilization. Some regions may legally prohibit primitive camping due to concern for the environment, or due to issues with crowds. In lieu of camping, mountaineers may choose to stay in

s.
The European alpine regions, in particular, have a large network of huts. Such huts exist at many different heights, including in the high mountains themselves – in extremely remote areas, more rudimentary shelters may exist. The mountain huts are of varying size and quality, but each is typically centred on a communal dining room and have dormitories equipped with mattresses, blankets or duvets, and pillows; guests are expected to bring and use their own
sleeping bag liners. The facilities are usually rudimentary, but, given their locations, huts offer vital shelter, make routes more widely accessible (by allowing journeys to be broken and reducing the weight of equipment needing to be carried), and offer good value. In Europe, all huts are staffed during the summer (mid-June to mid-September) and some are staffed in the spring (mid-March to mid-May). Elsewhere, huts may also be open in the fall. Huts also may have a part that is always open, but unstaffed, a so-called winter hut.
When open and staffed, the huts are generally run by full-time employees, but some are staffed on a voluntary basis by members of alpine clubs. The manager of the hut, termed a guardian or warden in Europe, will usually also sell refreshments and meals, both to those visiting only for the day and to those staying overnight. The offering is surprisingly wide, given that most supplies, often including fresh water, must be flown in by helicopter, and may include glucose-based snacks (such as candy bars) on which climbers and walkers wish to stock up, cakes and pastries made at the hut, a variety of hot and cold drinks (including beer and wine), and high carbohydrate dinners in the evenings. Not all huts offer a catered service, though, and visitors may need to provide for themselves. Some huts offer facilities for both, enabling visitors wishing to keep costs down to bring their own food and cooking equipment and to cater using the facilities provided. Booking for overnight stays at huts is deemed obligatory, and in many cases is essential as some popular huts, even with more than 100 bed spaces, may be full during good weather and at weekends. Once made, the cancellation of a reservation is advised as a matter of courtesy – and, indeed, potentially of safety, as many huts keep a record of where climbers and walkers state they plan to walk to next. Most huts may be contacted by telephone and most take credit cards as a means of payment.
In the UK the term "hut" is used for any cottage or cabin used as a base for walkers or climbers. These are mostly owned by mountaineering clubs for use by members or visiting clubs and generally do not have wardens or permanent staff, but have cooking and washing facilities and heating. In the Scottish Highlands small simple unstaffed shelters without cooking facilities known as
"bothies" are maintained to break up cross country long routes and act as base camps to certain mountains.

s are another way to shelter high on the mountain. Some climbers do not use tents at high altitudes unless the snow conditions do not allow for snow caving, since snow caves are silent and much warmer than tents. They can be built relatively easily, given sufficient time, using a snow shovel. The temperature of a correctly made snow cave will hover around freezing, which relative to outside temperatures can be very warm. They can be dug anywhere where there is at least four feet of snow. The addition of a good quality bivouac bag and closed cell foam sleeping mat will also increase the warmth of the snow cave. Another shelter that works well is a
quinzee, which is excavated from a pile of snow that has been work hardened or sintered (typically by stomping).

s. When climbing mountains, there are two types of hazards, ''objective'' (mountain-based) and ''subjective (human-based)''. Objective hazards relate to the environment, and may include inclement weather conditions, dangerous terrain, duration of

In terms of objective hazards, the dangers mountaineers face include loose or falling rocks, falling ice, snow-

From 1947 to 2018 in the United States "2,799 people were reported to be involved in mountaineering accidents and 43% of these accidents resulted in death."
Climbers themselves are responsible for nearly all climbing accidents.
When planning and preparing for a trip, safe climbers know what hazards to look for and how to recognize them. In situations where hazards are not able to be avoided, the climber must use their decision-making skills to
mitigate those hazards. Climbers improve upon their ability to become a safe decision maker and recognize hazards by receiving proper education, training, practice, and experience as well as learning how to spot
personal bias.

), both of which can be fatal within 24 hours.
In high mountains, atmospheric pressure is lower and this means that less oxygen is available to breathe.[ This is the underlying cause of altitude sickness. Everyone needs to acclimatise, even exceptional mountaineers that have been to high altitude before.] Generally speaking, mountaineers start using bottled oxygen when they climb above 7,000 m. Exceptional mountaineers have climbed 8000-metre peaks (including Everest

This is a life-threatening illness that must be dealt with right away. While mountaineering, snow and ice can be used to cool the body and head.

The best treatment for hypothermia is to deal with it before it occurs, using preventative measures instead of waiting for symptoms to appear. Mountaineering requires a slower pace to avoid sweating and fatigue that could lead to these dangerous conditions. Other tips for preventing hypothermia include staying well fed and hydrated, putting on more clothes when feeling cold, and wearing adequate equipment to keep warm and dry.
Motivations and Spiritual Dimensions
Alpinism, beyond its physical and technical demands, serves as a deeply personal and often spiritual pursuit. Many climbers describe their experiences in the mountains as moments of transformation, transcendence, and profound meaning. The solitude of high altitude environments, the exposure to natural elements, and the life or death stakes frequently encountered can bring climbers face to face with existential questions, bringing a sense of connection to forces larger than themselves.
Research in psychology supports these claims of transcendence. Elite mountaineers and base jumpers score highly in traits related to self transcendence, personality features associated with spirituality, mindfulness, and a search for meaning. Specifically, they highlight three key character traits associated with self transcendence: self directedness or a sense of purpose, cooperativeness meaning empathy and a sense of connectedness with others, and self
In philosophy, the self is an individual's own being, knowledge, and values, and the relationship between these attributes.
The first-person perspective distinguishes selfhood from personal identity. Whereas "identity" is (literally) same ...
transcendence itself or the capacity to feel part of something greater than oneself, often expressed through spiritual or mystical experience.These traits help explain why some individuals are drawn to high-risk, high-reward experiences that facilitate altered states of consciousness and deep reflection.
The motivations behind seeking these high risk situations through mountaineering are often rooted in a sense of personal calling. Climbers articulate their drive not simply as thrill seeking but as a vocation, and pursuing a spiritually fulfilling, to feel something close to destiny, purpose, and alignment with one’s deeper self. This supports earlier work that revealed that climbers often experience spiritual growth, emotional release, and a stronger sense of self through their expeditions.
Much of this is due to the way mountains have long been regarded as sacred in numerous cultures, and seen as bridges between the earthly and the divine. This perception continues in modern mountaineering, where the act of climbing is sometimes likened to a pilgrimage
A pilgrimage is a travel, journey to a holy place, which can lead to a personal transformation, after which the pilgrim returns to their daily life. A pilgrim (from the Latin ''peregrinus'') is a traveler (literally one who has come from afar) w ...
. The experience is not solely about physical conquest but about spiritual engagement with the mountain landscape, often resulting in a reverent relationship with nature.
Flow states as periods of deep focus and loss of time awareness are commonly reported by climbers. These states are central to the appeal of alpinism, providing psychological clarity and a sense of unity with the environment. Such experiences can be transformative, allowing climbers to tap into a higher sense of presence and well-being.

Alpinism encompasses more than physical accomplishment, but is often a gateway to inner exploration, emotional catharsis, and spiritual insight. Whether understood through scientific studies or personal narratives, the motivations behind alpinism frequently include a desire for transcendence, connection, and meaning beyond the summit.
Styles of mountaineering

.
Expedition style
The alpine style contrasts with "expedition style". With this style, climbers will carry large amounts of equipment and provisions up and down the mountain, slowly making upward progress. Climbing in an expedition style is preferred if the summit is very high or distant from civilization. Mountaineers who use this style are usually, but not always, part of a large team of climbers and support staff (such as porters and guides). To cover large distances with their massive amounts of gear, sleds and pack animals are commonly used. Climbers will set up multiple camps along the mountain, and will haul their gear up the mountain multiple times, returning to a lower camp after each haul until all the gear is at a higher camp; and repeating this procedure until they reach the summit. This technique is also helpful for acclimatization. While it is the original style in which high mountains were climbed, expedition style is rare these days as more mountains have become accessible to the general public with air travel
Air travel is a form of travel in vehicles such as airplanes, jet aircraft, helicopters, hot air balloons, blimps, Glider (aircraft), gliders, Hang gliding, hang gliders, parachuting, parachutes, or anything else that can sustain flight. and the penetration of highways

. 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.
