96-762: Presanella is a mountain in the Adamello-Presanella range of the Italian Alps of northern Italy . Presanella has an elevation of 3,558 meters and is located in the Adamello Brenta National Park within the Trentino province of Italy. Presanella may have first been climbed by surveyors in 1854. Eduard Pechmann's 1865 Notizen zur Höhen- und Profilkarte has Presanella's height with two digits precision (1878.26 Viennese Klaster or 3,562.1 m), which in this list indicated that
192-601: A tourist activity. There are different activities associated with the sport. 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
288-409: 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
384-428: A biotemperature below 1.5 °C (34.7 °F). Mountain environments are particularly sensitive to anthropogenic climate change and are currently undergoing alterations unprecedented in last 10,000 years. The effect of global warming on mountain regions (relative to lowlands) is still an active area of study. Observational studies show that highlands are warming faster than nearby lowlands, but when compared globally,
480-407: A climber who ascends the rock. The first climber, called the leader , will reach a point on the rock and then build an anchor , which will secure subsequent climbers. Anchors could be created by using slings around a tree or boulder, or by using protection devices like cams and nuts . Once anchored, the leader will then belay the climber coming up from below. Once the follower reaches the leader,
576-426: 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
672-559: A large body of professional guides, equipment, and methodologies. In the early years of the " golden age ", scientific pursuits were intermixed with the sport, such as by the physicist John Tyndall . In the later years, it shifted to a more competitive orientation as pure sportsmen came to dominate the London-based Alpine Club and alpine mountaineering overall. The first president of the Alpine Club, John Ball ,
768-607: A large variety of techniques and philosophies (including grading and guidebooks ) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee -recognized world organization for mountaineering and climbing. The consequences of mountaineering on
864-401: A light bivouac sack . Typical shelters used for camping include tents and bivouac sacks . 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
960-707: 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. Where conditions permit, snow caves are another way to shelter high on
1056-525: A measurement was taken from the summit during the trigonometric survey, which for Presanella was done in 1854. This possible ascent is otherwise unrecorded. In 1862, the Viennese jurist de:Anton von Ruthner and the guides Kuenz from Martell and Delpero from Vermiglio ascended the 3043 m Passo di Cercen to the West of Presanella. They attempted the western summit (Cima di Vermiglio, 3458 m), then considered

#17327915691151152-464: A mountain is roughly equivalent to moving 80 kilometres (45 miles or 0.75° of latitude ) towards the nearest pole. This relationship is only approximate, however, since local factors such as proximity to oceans (such as the Arctic Ocean) can drastically modify the climate. As the altitude increases, the main form of precipitation becomes snow and the winds increase. The effect of
1248-481: A mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill , typically rising at least 300 metres (980 ft ) above the surrounding land. A few mountains are isolated summits , but most occur in mountain ranges . Mountains are formed through tectonic forces , erosion , or volcanism , which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through
1344-692: A period of 13 hours, they climbed over the Presanella glacier to the Bocca di Presanella and ascended the Northeast ridge. The first ascent over the 550 m North face was by the Aostan climbers Emilio Brocherel, Ugo Croux and P. Arici in 1906. Mountain A mountain is an elevated portion of the Earth's crust , generally with steep sides that show significant exposed bedrock . Although definitions vary,
1440-413: A rope team. For example, when traveling over glaciers , crevasses pose a grave danger to a climber who is not roped in. These giant cracks in the ice are not always visible as snow can be blown and freeze over the top to make a snowbridge . At times snowbridges can be as thin as a few inches and may collapse from people walking over them. Should a climber fall, being protected by a rope greatly reduces
1536-405: 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
1632-518: A second guide (either one Bertoldi or Giovanni Caturani, who gave up before the summit) had approached the mountain from the opposite side, starting in the Rocchetta valley, and climbing the Southeast ridge in a storm. The first people to ascend Presanella over the steep North side were Johann “Kederbacher” Grill and Bonifacio Nicolussi guiding Bruno Wagner and Edward Kratky. On 4 August 1881, over
1728-648: A significant role in religion. There are for example a number of sacred mountains within Greece such as Mount Olympus which was held to be the home of the gods. In Japanese culture, the 3,776.24 m (12,389.2 ft) volcano of Mount Fuji is also held to be sacred with tens of thousands of Japanese ascending it each year. Mount Kailash , in the Tibet Autonomous Region of China, is considered to be sacred in four religions: Hinduism, Bon , Buddhism, and Jainism . In Ireland, pilgrimages are made up
1824-495: A variety of hazards . 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 exposure , and other environmental conditions. Subjective hazards relate to a climber's poor judgement, poor planning, lack of skills, faulty analysis and conclusions, or inadequate conditioning. In terms of objective hazards,
1920-535: 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
2016-471: A whole, 24% of the Earth's land mass is mountainous. There are three main types of mountains: volcanic , fold , and block . All three types are formed from plate tectonics : when portions of the Earth's crust move, crumple, and dive. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of

#17327915691152112-464: A young generation of Norwegian mountaineers such as George Paus , Eilert Sundt and Kristian Tandberg appeared, and later founded Norsk Tindeklub , the third oldest mountaineering association in the world. By the turn of the 20th century, mountaineering had acquired a more international flavour. In 1897 Mount Saint Elias (18,008 ft (5,489 m)) on the Alaska - Yukon border was summitted by
2208-452: Is El Alto , Bolivia, at 4,150 metres (13,620 ft), which has a highly diverse service and manufacturing economy and a population of nearly 1 million. Traditional mountain societies rely on agriculture, with higher risk of crop failure than at lower elevations. Minerals often occur in mountains, with mining being an important component of the economics of some mountain-based societies. More recently, tourism has become more important to
2304-571: Is Mount Everest in the Himalayas of Asia , whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft). The tallest mountain including submarine terrain is Mauna Kea in Hawaii from its underwater base at 9,330 m (30,610 ft) and some scientists consider it to be
2400-478: Is a poor conductor of heat, so a parcel of air will rise and fall without exchanging heat. This is known as an adiabatic process , which has a characteristic pressure-temperature dependence. As the pressure gets lower, the temperature decreases. The rate of decrease of temperature with elevation is known as the adiabatic lapse rate , which is approximately 9.8 °C per kilometre (or 5.4 °F (3.0 °C) per 1000 feet) of altitude. The presence of water in

Mountaineering-related activities include traditional outdoor climbing , skiing , and traversing via ferratas that have become sports in their own right. Indoor climbing , sport climbing , and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports . Mountains often play
2592-520: Is a set of outdoor activities that involves ascending mountains . Mountaineering-related activities include traditional outdoor climbing , skiing , and traversing via ferratas that have become sports in their own right. Indoor climbing , sport climbing , and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports . Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to
2688-435: Is also a prerequisite of success in all aspects of mountaineering. Alpine rock climbing 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
2784-441: 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). Igloos are used by some climbers, but are deceptively difficult to build and require specific snow conditions. Mountaineers face
2880-510: Is considered to be the discoverer of the Dolomites , which for decades were the focus of climbers like Paul Grohmann and Angelo Dibona . At that time, the edelweiss also established itself as a symbol of alpinists and mountaineers. In the 19th century, the focus of mountaineering turned towards mountains beyond the Alps. One of the earliest mountain areas to be explored beyond the Alps in

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

3072-556: Is not enough oxygen to support human life. This is sometimes referred to as the " death zone ". The summits of Mount Everest and K2 are in the death zone. Mountains are generally less preferable for human habitation than lowlands, because of harsh weather and little level ground suitable for agriculture . While 7% of the land area of Earth is above 2,500 metres (8,200 ft), only 140 million people live above that altitude and only 20-30 million people above 3,000 metres (9,800 ft) elevation. About half of mountain dwellers live in
3168-508: Is the 1100 AD ascent of the Untersberg . The famous poet Petrarch describes his 26 April 1336 ascent of Mount Ventoux (1,912 m (6,273 ft)) in one of his epistolae familiares , claiming to be inspired by Philip V of Macedon 's ascent of Mount Haemo . For most of antiquity, climbing mountains was a practical or symbolic activity, usually undertaken for economic, political, or religious purposes. A commonly cited example
3264-456: Is the 1492 ascent of Mont Aiguille (2,085 m (6,841 ft)) by Antoine de Ville, a French military officer and lord of Domjulien and Beaupré. Because ropes, ladders and iron hooks were used, and because it was the first climb of any technical difficulty to be officially verified, this ascent is widely recognized as being the birth of mountaineering. Conrad Gessner , A mid-16th Century physician, botanist and naturalist from Switzerland,
3360-457: Is the highest mountain on Earth, at 8,848 metres (29,029 ft). There are at least 100 mountains with heights of over 7,200 metres (23,622 ft) above sea level, all of which are located in central and southern Asia. The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Denali , Mount Kilimanjaro and Nanga Parbat are possible candidates for
3456-525: Is the largest mountain on Earth in terms of base area (about 2,000 sq mi or 5,200 km ) and volume (about 18,000 cu mi or 75,000 km ). Mount Kilimanjaro is the largest non-shield volcano in terms of both base area (245 sq mi or 635 km ) and volume (1,150 cu mi or 4,793 km ). Mount Logan is the largest non-volcanic mountain in base area (120 sq mi or 311 km ). The highest mountains above sea level are also not those with peaks farthest from
3552-402: 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 physical fitness and familiarity with the wilderness is necessary to complete a hike; it
3648-650: Is widely recognized as being the first person to hike and climb for sheer pleasure. In the Andes , around the late 1400s and early 1500s many ascents were made of extremely high peaks by the Incas and their subjects. The highest they are known for certain to have climbed is 6739 m at the summit of Volcan Llullaillaco . The Age of Enlightenment and the Romantic era marked a change of attitudes towards high mountains. In 1757 Swiss scientist Horace-Bénédict de Saussure made

However, the highest mountains were rarely visited early on, and were often associated with supernatural or religious concepts. Nonetheless, there are many documented examples of people climbing mountains prior to the formal development of the sport in the 19th century, although many of these stories are sometimes considered fictional or legendary. A rare medieval example of mountaineering
3840-475: The Andes , Central Asia, and Africa. With limited access to infrastructure, only a handful of human communities exist above 4,000 metres (13,000 ft) of elevation. Many are small and have heavily specialized economies, often relying on industries such as agriculture, mining, and tourism. An example of such a specialized town is La Rinconada, Peru , a gold-mining town and the highest elevation human habitation at 5,100 metres (16,700 ft). A counterexample
3936-649: The Basin and Range Province of Western North America. These areas often occur when the regional stress is extensional and the crust is thinned. During and following uplift, mountains are subjected to the agents of erosion (water, wind, ice, and gravity) which gradually wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks , knife-edge arêtes , and bowl-shaped cirques that can contain lakes. Plateau mountains, such as

4032-468: The Catskills , are formed from the erosion of an uplifted plateau. Climate in the mountains becomes colder at high elevations , due to an interaction between radiation and convection. Sunlight in the visible spectrum hits the ground and heats it. The ground then heats the air at the surface. If radiation were the only way to transfer heat from the ground to space, the greenhouse effect of gases in
4128-770: The Duke of the Abruzzi and party. In 1879–1880 the exploration of the highest Andes in South America began when English mountaineer Edward Whymper climbed Chimborazo (20,549 ft (6,263 m)) and explored the mountains of Ecuador. It took until the late 19th century for European explorers to penetrate Africa. Mount Kilimanjaro in Africa was climbed in 1889 by Austrian mountaineer Ludwig Purtscheller and German geologist Hans Meyer , Mount Kenya in 1899 by Halford Mackinder . The greatest mountain range to be conquered
4224-794: The French Federation of Mountaineering and Climbing , remain independent. The premier award in mountaineering is the privately granted Piolet d'Or , which has expanded from a single recognition to multiple. While there are many competitions, particularly in toproped climbing wall disciplines, there are no "official" world championships or other similar competitions for mountaineering broadly. 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. The term "walk-up" or "trek"
4320-579: The Golden Age of Alpinism , with the first mountaineering club – the Alpine Club – being founded in 1857. One of the most dramatic events was the spectacular first ascent of the Matterhorn in 1865 by a party led by English illustrator Edward Whymper , in which four of the party members fell to their deaths. By this point the sport of mountaineering had largely reached its modern form, with
4416-895: The Grossglockner in 1800, the Ortler in 1804, the Jungfrau in 1811, the Finsteraarhorn in 1812, and the Breithorn in 1813. In 1808, Marie Paradis became the first woman to climb Mont Blanc, followed in 1838 by Henriette d'Angeville . The beginning of mountaineering as a sport in the UK is generally dated to the ascent of the Wetterhorn in 1854 by English mountaineer Sir Alfred Wills , who made mountaineering fashionable in Britain. This inaugurated what became known as
4512-521: The vasodilator padutin , and a stimulant tea made from coca leaves. K2 (8,611m), the second-highest peak in the world, was first scaled in 1954 by Lino Lacedelli and Achille Compagnoni . In 1964, the final eight-thousander to be climbed was Shishapangma (8,013m), the lowest of all the 8,000-metre peaks. Reinhold Messner from the Dolomites mountain range (Italy) was then the first to climb all eight-thousanders up to 1986, in addition to being
4608-525: The 19th century were the mountains of Norway —particularly Jotunheimen —where British mountaineers such as William Cecil Slingsby , Harold Raeburn and Howard Priestman were early pioneers. Slingsby's book Norway, the Northern Playground contributed greatly to the popularization of mountaineering in Norway among the international mountaineering community. Around the turn of the century,
4704-621: The 952 metres (3,123 ft) Mount Brandon by Irish Catholics . The Himalayan peak of Nanda Devi is associated with the Hindu goddesses Nanda and Sunanda; it has been off-limits to climbers since 1983. Mount Ararat is a sacred mountain, as it is believed to be the landing place of Noah's Ark . In Europe and especially in the Alps , summit crosses are often erected on the tops of prominent mountains. Heights of mountains are typically measured above sea level . Using this metric, Mount Everest

Only three weeks later, on 17 September 1864, the Austrian explorer Julius Payer and his guide Girolamo Botteri stood on the summit, finding there to their surprise and disappointment a cairn built by Freshfield's party. Payer, Botteri and
4896-455: The US. Fold mountains occur when two plates collide: shortening occurs along thrust faults and the crust is overthickened. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume forced downward into the mantle. Thus

#17327915691154992-622: The action of weathering , through slumping and other forms of mass wasting , as well as through erosion by rivers and glaciers . High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction, such as mining and logging , along with recreation, such as mountain climbing and skiing . The highest mountain on Earth
5088-581: The adjacent elevation, is impressive or notable." Whether a landform is called a mountain may depend on local usage. John Whittow's Dictionary of Physical Geography states "Some authorities regard eminences above 600 metres (1,969 ft) as mountains, those below being referred to as hills." In the United Kingdom and the Republic of Ireland, a mountain is usually defined as any summit at least 2,000 feet (610 m) high, which accords with
5184-553: The atmosphere complicates the process of convection. Water vapor contains latent heat of vaporization . As air rises and cools, it eventually becomes saturated and cannot hold its quantity of water vapor. The water vapor condenses to form clouds and releases heat, which changes the lapse rate from the dry adiabatic lapse rate to the moist adiabatic lapse rate (5.5 °C per kilometre or 3 °F (1.7 °C) per 1000 feet) The actual lapse rate can vary by altitude and by location. Therefore, moving up 100 m (330 ft) on
5280-429: The atmosphere would keep the ground at roughly 333 K (60 °C; 140 °F), and the temperature would decay exponentially with height. However, when air is hot, it tends to expand, which lowers its density. Thus, hot air tends to rise and transfer heat upward. This is the process of convection . Convection comes to equilibrium when a parcel of air at a given altitude has the same density as its surroundings. Air

Using various techniques from alpine skiing to ascend/descend a mountain is a form of the sport by itself, called ski mountaineering . Ascending and descending a steep snow slope safely requires the use of an ice axe and different footwork techniques that have been developed over
5472-568: The centre of the Earth, because the figure of the Earth is not spherical. Sea level closer to the equator is several miles farther from the centre of the Earth. The summit of Chimborazo , Ecuador's tallest mountain, is usually considered to be the farthest point from the Earth's centre, although the southern summit of Peru's tallest mountain, Huascarán , is another contender. Both have elevations above sea level more than 2 kilometres (6,600 ft) less than that of Everest. Mountain climbing Mountaineering , mountain climbing , or alpinism
5568-459: The climate on the ecology at an elevation can be largely captured through a combination of amount of precipitation, and the biotemperature , as described by Leslie Holdridge in 1947. Biotemperature is the mean temperature; all temperatures below 0 °C (32 °F) are considered to be 0 °C. When the temperature is below 0 °C, plants are dormant, so the exact temperature is unimportant. The peaks of mountains with permanent snow can have
5664-534: The conditions above and below a particular zone will be inhospitable and thus constrain their movements or dispersal . These isolated ecological systems are known as sky islands . Altitudinal zones tend to follow a typical pattern. At the highest elevations, trees cannot grow, and whatever life may be present will be of the alpine type, resembling tundra . Just below the tree line , one may find subalpine forests of needleleaf trees, which can withstand cold, dry conditions. Below that, montane forests grow. In
5760-476: The continental crust is normally much thicker under mountains, compared to lower lying areas. Rock can fold either symmetrically or asymmetrically. The upfolds are anticlines and the downfolds are synclines : in asymmetric folding there may also be recumbent and overturned folds. The Balkan Mountains and the Jura Mountains are examples of fold mountains. Block mountains are caused by faults in
5856-513: The crust: a plane where rocks have moved past each other. When rocks on one side of a fault rise relative to the other, it can form a mountain. The uplifted blocks are block mountains or horsts . The intervening dropped blocks are termed graben : these can be small or form extensive rift valley systems. This kind of landscape can be seen in East Africa , the Vosges and Rhine valley, and

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
6048-548: The definition since the 1970s. Any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US. The UN Environmental Programme 's definition of "mountainous environment" includes any of the following: Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As
6144-460: The dry season and in semiarid areas such as in central Asia. Alpine ecosystems can be particularly climatically sensitive. Many mid-latitude mountains act as cold climate refugia, with the ecosystems occupying small environmental niches. As well as the direct influence that the change in climate can have on an ecosystem, there is also the indirect one on the soils from changes in stability and soil development. The colder climate on mountains affects
6240-523: The economies of mountain communities, with developments focused around attractions such as national parks and ski resorts . Approximately 80% of mountain people live below the poverty line. Most of the world's rivers are fed from mountain sources, with snow acting as a storage mechanism for downstream users. More than half of humanity depends on mountains for water. In geopolitics , mountains are often seen as natural boundaries between polities. Mountaineering , mountain climbing, or alpinism
6336-428: The effect disappears. Precipitation in highland areas is not increasing as quickly as in lowland areas. Climate modeling give mixed signals about whether a particular highland area will have increased or decreased precipitation. Climate change has started to affect the physical and ecological systems of mountains. In recent decades mountain ice caps and glaciers have experienced accelerating ice loss. The melting of

Volcanoes are formed when a plate is pushed below another plate , or at a mid-ocean ridge or hotspot . At a depth of around 100 km (60 mi), melting occurs in rock above the slab (due to the addition of water), and forms magma that reaches

He then offered a reward to anyone who could climb the mountain, which was claimed in 1786 by Jacques Balmat and Michel-Gabriel Paccard . The climb is usually considered an epochal event in the history of mountaineering, a symbolic mark of the birth of the sport. By the early 19th century, many of the alpine peaks were reached, including

A number of Gurkha sepoys were trained as expert mountaineers by Charles Granville Bruce , and a good deal of exploration was accomplished by them. In 1902 the Eckenstein–Crowley Expedition, led by English mountaineer Oscar Eckenstein and English occultist Aleister Crowley

Long the domain of the wealthy elite and their agents, the emergence of the middle-class in the 19th and 20th centuries resulted in mass interest in mountaineering. It became a popular pastime and hobby of many people. Some have come to criticize the sport as becoming too much of
6816-498: The glaciers, permafrost and snow has caused underlying surfaces to become increasingly unstable. Landslip hazards have increased in both number and magnitude due to climate change. Patterns of river discharge will also be significantly affected by climate change, which in turn will have significant impacts on communities that rely on water fed from alpine sources. Nearly half of mountain areas provide essential or supportive water resources for mainly urban populations, in particular during
6912-534: 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
7008-464: The highest by the people from Vermiglio, but failed to reach the summit, partly because Delpero did not have glacier experience. The first well-recorded ascent was two years later by François Devouassoud accompanied by Delpero and guiding the English gentlemen R. Melville Beachcroft, James Douglas Walker, and Douglas William Freshfield . Like Ruthner, the party approached Presanella from Vermiglio from
7104-418: 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
7200-401: 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
7296-404: 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 aid climbing techniques. This involves
7392-448: The most famous base camps. 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 mountain huts . The European alpine regions, in particular, have a large network of huts. Such huts exist at many different heights, including in
7488-424: 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
7584-535: The natural environment can be seen in terms of individual components of the environment (land relief, soil, vegetation, fauna, and landscape) and the location/zone of mountaineering activity (hiking, trekking, or climbing zone). Mountaineering impacts communities on economic, political, social and cultural levels, often leading to changes in people's worldviews influenced by globalization, specifically foreign cultures and lifestyles. Humans have been present in mountains since prehistory. The remains of Ötzi , who lived in
7680-520: The official UK government's definition that a mountain, for the purposes of access, is a summit of 2,000 feet (610 m) or higher. In addition, some definitions also include a topographical prominence requirement, such as that the mountain rises 300 metres (984 ft) above the surrounding terrain. At one time, the United States Board on Geographic Names defined a mountain as being 1,000 feet (305 m) or taller, but has abandoned
7776-542: The past century, such as the French technique and German technique . Teams of climbers may choose to attach everyone together with a rope, to form a rope team. The team may then secure themselves by attaching the rope to anchors. These anchors are sometimes unreliable and include snow stakes or pickets, deadman devices called flukes , or buried equipment or rocks. Bollards , which are simply carved out of consolidated snow or ice, also sometimes serve as anchors. Alternatively,
7872-527: The plants and animals residing on mountains. A particular set of plants and animals tend to be adapted to a relatively narrow range of climate. Thus, ecosystems tend to lie along elevation bands of roughly constant climate. This is called altitudinal zonation . In regions with dry climates, the tendency of mountains to have higher precipitation as well as lower temperatures also provides for varying conditions, which enhances zonation. Some plants and animals found in altitudinal zones tend to become isolated since
7968-403: The risk of injury or death. The other members of the rope team may proceed with a crevasse rescue to pull the fallen climber from the crevasse. For extremely slippery or steep snow, ice, and mixed rock and ice terrain climbers must use more advanced techniques, called ice climbing or mixed climbing. Specialized tools such as ice screws and ice picks help climbers build anchors and move up
8064-536: 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 climbing wall -based competition – by the International Olympic Committee ; on a club level, the prominent international sport federation the UIAA counts numerous national alpine clubs as its members, while others, such as The Mountaineers and
8160-514: The surface. When the magma reaches the surface, it often builds a volcanic mountain, such as a shield volcano or a stratovolcano . Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines. The magma does not have to reach the surface in order to create a mountain: magma that solidifies below ground can still form dome mountains , such as Navajo Mountain in
8256-477: The tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Ocean floor. The highest mountains are not generally the most voluminous. Mauna Loa (4,169 m or 13,678 ft)
8352-481: The tallest on earth. There is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain. In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which, relatively to
8448-473: The temperate portions of the earth, those forests tend to be needleleaf trees, while in the tropics, they can be broadleaf trees growing in a rainforest . The highest known permanently tolerable altitude is at 5,950 metres (19,520 ft). At very high altitudes, the decreasing atmospheric pressure means that less oxygen is available for breathing, and there is less protection against solar radiation ( UV ). Above 8,000 metres (26,000 ft) elevation, there
8544-418: 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. Climbers use
8640-503: 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. Compacted snow conditions allow mountaineers to progress on foot. Frequently crampons are required to travel efficiently and safely over snow and ice. Crampons attach to
8736-439: 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
8832-463: Was also a pioneer in developing new equipment and climbing methods. He started using shorter ice axes that could be used single-handedly, designed the modern crampons , and improved on the nail patterns used for the climbing boots. By the 1950s, all the eight-thousanders but two had been climbed starting with Annapurna in 1950 by Maurice Herzog and Louis Lachenal on the 1950 French Annapurna expedition . The highest of these peaks Mount Everest
8928-481: Was climbed in 1953 after the British had made several attempts in the 1920s; the 1922 expedition reached 8,320 metres (27,300 ft) before being aborted on the third summit attempt after an avalanche killed seven porters. The 1924 expedition saw another height record achieved but still failed to reach the summit with confirmation when George Mallory and Andrew Irvine disappeared on the final attempt. The summit
9024-477: Was finally reached on 29 May 1953 by Sir Edmund Hillary and Tenzing Norgay from the south side in Nepal . Just a few months later, Hermann Buhl made the first ascent of Nanga Parbat (8,125 m), on the 1953 German–Austrian Nanga Parbat expedition , completing the last 1,300 meters walking alone, self-medicating with pervitin (based on the stimulant methamphetamine used by soldiers during World War II),
9120-737: Was the Himalayas in South Asia. They had initially been surveyed by the British Empire for military and strategic reasons. In 1892 Sir William Martin Conway explored the Karakoram Himalayas, and climbed a peak of 23,000 ft (7,000 m). In 1895 Albert F. Mummery died while attempting Nanga Parbat , while in 1899 Douglas Freshfield took an expedition to the snowy regions of Sikkim . In 1899, 1903, 1906, and 1908 American mountaineer Fanny Bullock Workman (one of
9216-413: Was the first to attempt to scale K2 . They reached 22,000 feet (6,700 m) before turning back due to weather and other mishaps. Undaunted, in 1905 Crowley led the first expedition to Kangchenjunga , the third highest mountain in the world, in an attempt which Isserman, Angas Weaver and Molenaar describe as "misguided" and "lamentable" due to Crowley's many failings as an expedition leader.
