(Island Peak) in Nepal, 2004]]

Mountaineering or mountain climbing is the sport, hobby or profession of hiking, skiing, and climbing mountains. While mountaineering began as attempts to reach the highest point of unclimbed mountains, it has branched into specialisations that address different aspects of the mountain and consists of three areas: rock-craft, snow-craft and skiing, depending on whether the route chosen is over rock, snow or ice. All require experience, athletic ability, and technical knowledge to maintain safety. The UIAA or Union Internationale des Associations d'Alpinisme is the world governing body in mountaineering and climbing, addressing issues like access, medical, mountain protection, safety, youth and ice climbing.

Technique

Snow

Compacted snow conditions allow mountaineers to progress on foot. Frequently crampons are required to travel efficiently over snow and ice. Crampons have 8-14 spikes and are attached to a mountaineer's boots. They are used on hard snow (neve) and ice to provide additional traction and allow very steep ascents and descents. Varieties range from lightweight aluminium models intended for walking on snow covered glaciers, to aggressive steel models intended for vertical and overhanging ice and rock. Snowshoes can be used to walk through deep snow. Skis can be used everywhere snowshoes can and also in steeper, more alpine landscapes, although it takes considerable practice to develop strong skills for difficult terrain. Combining the techniques of alpine skiing and mountaineering to ascend and descend a mountain is a form of the sport by itself, called ski mountaineering. Ascending and descending a snow slope safely requires the use of an ice axe and many different footwork techniques that have been developed over the past century, mainly in Europe. The progression of footwork from the lowest angle slopes to the steepest terrain is first to splay the feet to a rising traverse, to kicking steps, to front pointing the crampons. The progression of ice axe technique from the lowest angle slopes to the steepest terrain is to use the ice axe first as a walking stick, then a stake, then to use the front pick as a dagger below the shoulders or above, and finally to swing the pick into the slope over the head. These various techniques may involve questions of differing ice-axe design depending on terrain, and even whether a mountaineer uses one or two ice axes. Anchors for the rope in snow are sometimes unreliable, and include snow stakes, called pickets, deadman devices called flukes which are fashioned from aluminium, or devised from buried objects that might include an ice axe, skis, rocks or other objects. Bollards, which are simply carved out of consolidated snow or ice, also sometimes serve as anchors.

Glaciers

When travelling over glaciers, crevasses pose a grave danger. 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. Climbers use a system of ropes to protect themselves from such hazards. Basic gear for glacier travel includes crampons and ice axes. Teams of two to five climbers tie into a rope equally spaced. If a climber begins to fall the other members of the team perform a self-arrest to stop the fall. The other members of the team enact a crevasse rescue to pull the fallen climber from the crevasse.

Ice

Multiple methods are used to safely travel over ice. If the terrain is steep but not vertical, then the lead climber can place ice screws in the ice and attach the rope for protection. Each climber on the team must clip past the anchor, and the last climber picks up the anchor itself. Occasionally, slinged icicles or bollards are also used. This allows for safety should the entire team be taken off their feet. This technique is known as Simul-climbing and is sometimes also used on steep snow and easy rock.

If the terrain becomes too steep, standard ice climbing techniques are used in which each climber is belayed, moving one at a time.

==Shelter==

Climbers use a few different forms of shelter depending on the situation and conditions. Shelter is a very important aspect of safety for the climber as the weather in the mountains may be very unpredictable. Tall mountains may require many days of camping on the mountain.

Base Camp

The "Base Camp" of a mountain is an area used for staging an attempt at the summit. Base camps are positioned to be safe from the harsher conditions above. There are base camps on many popular or dangerous mountains. Where the summit cannot be reached from base camp in a single day, a mountain will have additional camps above base camp. For example, the southeast ridge route on Mount Everest has Base Camp plus (normally) camps I through IV.

Hut

The European alpine regions, in particular, have a network of mountain huts (called "refuges" in France, "rifugi" in Italy, "cabanes" in Switzerland, "Hütten" in Germany and Austria, "koča" in Slovenia, "refugios" in Spain and "hytte" in Norway). 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 to use their own sleeping bag liner. 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 unmanned, a so-called winter hut. When open and manned, the huts are generally run by full-time employees, but some are staffed on a voluntary basis by members of Alpine clubs (such as Swiss Alpine Club and Club alpin français). 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 Mars and Snickers 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 planned to walk to next. Most huts may be contacted by telephone and most take credit cards as a means of payment.

Bivouac (bivy or bivvy)

In the mountaineering context, a bivouac or "biv(v)y" is a makeshift resting or sleeping arrangement in which the climber has less than the full complement of shelter, food and equipment that would normally be present at a conventional campsite. This may involve simply getting a sleeping bag and Bivouac sack/bivvy bag and lying down to sleep. Typically bivvy bags are made from breathable waterproof membranes which stop the user sweating too much, which in sub zero environments can be very dangerous. Many times small partially sheltered areas such as a bergschrund, cracks in rocks or a trench dug in the snow are used to provide additional shelter from wind. These techniques were originally used only in emergency; however some climbers steadfastly committed to alpine style climbing specifically plan for bivouacs in order to save the weight of a tent when suitable snow conditions or time is unavailable for construction of a snow cave. The principal hazard associated with bivouacs is the greater level of exposure to cold and the elements.

Tent

Tents are the most common form of shelter used on the mountain. These may vary from simple tarps to much heavier designs intended to withstand harsh mountain conditions. In exposed positions, windbreaks of snow or rock may be required to shelter the tent. One of the downsides to tenting is that high winds and snow loads can be dangerous and may ultimately lead to the tent's failure and collapse. In addition, the constant flapping of the tent fabric can hinder sleep and raise doubts about the security of the shelter. When choosing a tent, alpinists tend to rely on specialised mountaineering tents that are specifically designed for high winds and moderate to heavy snow loads. Tent stakes can be buried in the snow ("deadman") for extra security.

Snow cave

Where conditions permit snow caves 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. 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 bivvy 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.

Hazards

Dangers in mountaineering are sometimes divided into two categories: objective hazards that exist without regard to the climber's presence, like rockfall, avalanches and inclement weather, and subjective hazards that relate only to factors introduced by the climber. Equipment failure and falls due to inattention, fatigue or inadequate technique are examples of subjective hazards. A route continually swept by avalanches and storms is said to have a high level of objective danger, whereas a technically far more difficult route that is relatively safe from these dangers may be regarded as objectively safer.

In all, mountaineers must concern themselves with dangers: falling rocks, falling ice, snow-avalanches, the climber falling, falls from ice slopes, falls down snow slopes, falls into crevasses and the dangers from altitude and weather. To select and follow a route using one's skills and experience to mitigate these dangers is to exercise the climber's craft.

Falling rocks

Every rock mountain is slowly disintegrating due to erosion, the process being especially rapid above the snow-line. Rock faces are constantly swept by falling stones, which may be possible to dodge. Falling rocks tend to form furrows in a mountain face, and these furrows (couloirs) have to be ascended with caution, their sides often being safe when the middle is stoneswept. Rocks fall more frequently on some days than on others, according to the recent weather. Ice formed during the night may temporarily bind rocks to the face but warmth of the day or lubricating water from melting snow or rain may easily dislodge these rocks. Local experience is a valuable help on determining typical rock fall on such routes.

The direction of the dip of rock strata sometimes determines the degree of danger on a particular face; the character of the rock must also be considered. Where stones fall frequently debris will be found below, whilst on snow slopes falling stones cut furrows visible from a great distance. In planning an ascent of a new peak or an unfamiliar route, mountaineers must look for such traces. When falling stones get mixed in considerable quantity with slushy snow or water a mud avalanche is formed (common in the Himalayas). It is vital to avoid camping in their possible line of fall.

Falling ice

The places where ice may fall can always be determined beforehand. It falls in the broken parts of glaciers (seracs) and from overhanging cornices formed on the crests of narrow ridges. Large icicles are often formed on steep rock faces, and these fall frequently in fine weather following cold and stormy days. They have to be avoided like falling stones. Seracs are slow in formation, and slow in arriving (by glacier motion) at a condition of unstable equilibrium. They generally fall in or just after the hottest part of the day. A skillful and experienced ice-man will usually devise a safe route through a most intricate ice-fall, but such places should be avoided in the afternoon of a hot day. Hanging glaciers (i.e. glaciers perched on steep slopes) often discharge themselves over steep rock-faces, the snout breaking off at intervals. They can always be detected by their debris below. Their track should be avoided.

Falls from rocks

A rock climber's skill is shown by their choice of handhold and foothold, and their adhesion to the holds once chosen. Much depends on the ability to estimate the capability of the rock to support the weight placed on it. Many loose rocks are quite firm enough to bear a person's weight, but experience is needed to know which can be trusted, and skill is required in transferring the weight to them without jerking. On rotten rocks the rope must be handled with special care, lest it should dislodge loose stones on to those below. Similar care must be given to handholds and footholds, for the same reason. When a horizontal traverse has to be made across very difficult rocks, a dangerous situation may arise unless at both ends of the traverse there are firm positions. Mutual assistance on hard rocks takes all manner of forms: two, or even three, people climbing on one another's shoulders, or using an ice axe propped up by others for a foothold. The great principle is that of co-operation, all the members of the party climbing with reference to the others, and not as independent units; each when moving must know what the climber in front and the one behind are doing. After bad weather steep rocks are often found covered with a veneer of ice (verglas), which may even render them inaccessible. Crampons are useful on such occasions.

Avalanches

Every year, 120 to 150 people die in small avalanches in the Alps alone. The vast majority are reasonably experienced male skiers aged 20–35 but also include ski instructors and guides. There is always a lot of pressure to risk a snow crossing. Turning back takes a lot of extra time and effort, supreme leadership, and most importantly there is seldom an avalanche that proves the right decision was made. Making the decision to turn around is especially hard if others are crossing the slope, but any next person could become the trigger.

There are many types of avalanche, but two types are of the most concern:

#Slab avalanche #:This type of avalanche occurs when a plate of snow breaks loose and starts sliding downhill; these are the largest and most dangerous. ##Hard slab avalanche #::This type of avalanche is formed by hard-packed snow in a cohesive slab. The slab will not break up easily as it slides down the hill, resulting in large blocks tumbling down the mountain. ##Soft slab avalanche #::This type of avalanche is formed again by a cohesive layer of snow bonded together, the slab tends to break up more easily. #Loose snow avalanche #:This type of avalanche is triggered by a small amount of moving snow that accumulates into a big slide. Also known as a "wet slide or point release" avalanche. This type of avalanche is deceptively dangerous as it can still knock a climber or skier off their feet and bury them, or sweep them over a cliff into a terrain trap.

Dangerous slides are most likely to occur on the same slopes preferred by many skiers: long and wide open, few trees or large rocks, 30 to 45 degrees of angle, large load of fresh snow, soon after a big storm, on a slope "lee to the storm". Solar radiation can trigger slides as well. These will typically be a point release or wet slough type of avalanche. The added weight of the wet slide can trigger a slab avalanche. Ninety percent of reported victims are caught in avalanches triggered by themselves or others in their group.

When going off-piste or travelling in alpine terrain, parties are advised to always carry: #avalanche beacon #probe #shovel (retrieving victims with a shovel instead of hands is five times faster) They are also advised to have had avalanche training. Ironically, expert skiers who have avalanche training make up a large percentage of avalanche fatalities; perhaps because they are the ones more likely to ski in areas prone to avalanches, and certainly because most people do not practice enough with their equipment to be truly fast and efficient rescuers.

Even with proper rescue equipment and training, there is a one-in-five chance of dying if caught in a significant avalanche, and only a 50/50 chance of being found alive if buried more than a few minutes. The best solution is to learn how to avoid risky conditions.

Ice slopes

.]] For travel on slopes consisting of ice or hard snow, crampons are a standard part of a mountaineer's equipment. While step-cutting can sometimes be used on snow slopes of moderate angle, this can be a slow and tiring process, which does not provide the higher security of crampons. However, in soft snow or powder, crampons are easily hampered by balling of snow, which reduces their effectiveness. In either case, an ice axe not only assists with balance but provides the climber with the possibility of self-arrest in case of a slip or fall. On a true ice slope however, an ice axe is rarely able to effect a self-arrest. As an additional safety precaution on steep ice slopes, the climbing rope is attached to ice screws buried into the ice.

True ice slopes are rare in Europe, though common in mountains in the tropics, where newly-fallen snow quickly thaws on the surface and becomes sodden below, so that the next night's frost turns the whole mass into a sheet of semi-solid ice.

Snow slopes

between France and Switzerland; two alpinists can be seen following the trail in the snow.]] Snow slopes are very common, and usually easy to ascend. At the foot of a snow or ice slope is generally a big crevasse, called a bergschrund, where the final slope of the mountain rises from a snow-field or glacier. Such bergschrunds are generally too wide to be stepped across, and must be crossed by a snow bridge, which needs careful testing and a painstaking use of the rope. A steep snow slope in bad condition may be dangerous, as the whole body of snow may start as an avalanche. Such slopes are less dangerous if ascended directly, rather than obliquely, for an oblique or horizontal track cuts them across and facilitates movement of the mass. New snow lying on ice is especially dangerous. Experience is needed for determining the feasibility of advancement over snow in doubtful condition. Snow on rocks is usually rotten unless it is thick; snow on snow is likely to be sound. A day or two of fine weather will usually bring new snow into sound condition. Snow cannot lie at a very steep angle, though it often deceives the eye as to its slope. Snow slopes seldom exceed 40°. Ice slopes may be much steeper. Snow slopes in early morning are usually hard and safe, but the same in the afternoon are quite soft and possibly dangerous; hence the advantage of an early start.

Crevasses

Crevasses are the slits or deep chasms formed in the substance of a glacier as it passes over an uneven bed. They may be open or hidden. In the lower part of a glacier the crevasses are open. Above the snow-line they are frequently hidden by arched-over accumulations of winter snow. The detection of hidden crevasses requires care and experience. After a fresh fall of snow they can only be detected by sounding with the pole of the ice axe, or by looking to right and left where the open extension of a partially hidden crevasse may be obvious. The safeguard against accident is the rope, and no one should ever cross a snow-covered glacier unless roped to one, or even better to two companions. Anyone venturing onto crevasses should be trained in crevasse rescue.

Weather

The primary dangers caused by bad weather centre around the changes it causes in snow and rock conditions, making movement suddenly much more arduous and hazardous than under normal circumstances. Whiteouts make it difficult to retrace a route while rain may prevent taking the easiest line only determined as such under dry conditions. In a storm the mountaineer who uses a compass for guidance has a great advantage over a merely empirical observer. In large snow-fields it is, of course, easier to go wrong than on rocks, but intelligence and experience are the best guides in safely navigating objective hazards.

Summer thunderstorms may produce intense lightning. If a climber happens to be standing on or near the summit, they risk being struck. There are many cases where people have been struck by lightning while climbing mountains. In most mountainous regions, local storms develop by late morning and early afternoon. Many climbers will get an "alpine start"; that is before or by first light so as to be on the way down when storms are intensifying in activity and lightning and other weather hazards are a distinct threat to safety. High winds can speed the onset of hypothermia, as well as damage equipment such as tents used for shelter. Under certain conditions, storms can also create waterfalls which can slow or stop climbing progress. A notable example is the Fohn wind acting upon the Eiger.

Altitude

Rapid ascent can lead to altitude sickness. The best treatment is to descend immediately. The climber's motto at high altitude is "climb high, sleep low", referring to the regimen of climbing higher to acclimatise but returning to lower elevation to sleep. In the South American Andes, the chewing of coca leaves has been traditionally used to treat altitude sickness symptoms.

Common symptoms of altitude sickness include severe headache, sleep problems, nausea, lack of appetite, lethargy and body ache. Mountain sickness may progress to HACE (High Altitude Cerebral Edema) and HAPE (High Altitude Pulmonary Edema), 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) without oxygen, almost always with a carefully planned program of acclimatisation.

Solar radiation

Solar radiation increases significantly as the atmosphere gets thinner with increasing altitude thereby absorbing less ultraviolet radiation. Snow cover reflecting the radiation can amplify the effects by up to 75% increasing the risks and damage from sunburn and snow blindness.

In 2005, researcher and mountaineer John Semple established that above-average ozone concentrations on the Tibetan plateau may pose an additional risk to climbers.

Volcanic activity

Some mountains are active volcanoes as in the case of the many stratovolcanoes that form the highest peaks in island arcs and in parts of the Andes. Some of these volcanic mountains may cause several hazards if they erupt, such as lahars, pyroclastic flows, rockfalls, lava flows, heavy tephra fall, volcanic bomb ejections and toxic gases.

Styles of mountaineering

There are two main styles of mountaineering: expedition climbing and alpinism.

In Europe mountaineering is referred to as alpinism. In the Americas this term refers to a particular style of mountain climbing that involves a mixture of ice climbing, rock climbing, and mixed climbing where climbers carry all their loads with them at all times. The term alpinism as used in the Americas contrasts with expedition style climbing (as commonly undertaken in the Himalayan region) where climbers use porters, pack animals, cooks, etc. to carry their loads and cook meals. 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 are necessary. 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 the expedition style as mountains can often be easily accessed by car or air, are at a lower altitude and can be climbed in a day or two.

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

Expedition climbing

uses multiple trips between camps to carry supplies up to higher camps

group sizes are 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

more time is spent on the mountain and this means climbers are exposed to objective hazards for a longer period of time

supplemental oxygen is frequently used

Alpinism

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

alpinism does 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

Locations

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 Carpathian Mountains. In North America climbers frequent the Rocky Mountains, the Sierra Nevada of California, the Cascades of the Pacific Northwest and the high peaks of Alaska. 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 Himalaya, Karakoram, Pamirs and Tien Shan. 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 Japanese Alps, the South Korean mountains, the Coast Mountains of British Columbia, the Scottish Highlands, and the mountains of Scandinavia, especially Norway.

History

made ascents into the Himalayas at the turn of the 20th century.]] Though it is unknown whether his intention was to reach a summit, "Ötzi" ascended at least in the Alps about 5,300 years ago. His remains were found at that altitude, preserved in a glacier.

The first recorded mountain ascent in the Common Era is Roman Emperor Hadrian's ascent of Etna (3,350 m) to see the sun rise in 121.

Peter III of Aragon climbed Canigou in the Pyrenees in the last quarter of the 13th century.

The first ascent of the Popocatépetl (5,426 m in Mexico) was reported in 1289 by members of a local tribe (Tecanuapas) Jean Buridan climbed Mont Ventoux around 1316. The Italian poet Petrarch wrote that on April 26, 1336 he, together with his brother and two servants, climbed to the top of Mont Ventoux (1,909 m). His account of the trip was composed later as a letter to his friend Dionigi di Borgo San Sepolcro.

The Rochemelon (3,538 m) in the Italian Alps was climbed in 1358.

In the late 15th and early 16th centuries, ascents were made of numerous high peaks in the Andes, for religious purposes by the citizens of the Inca Empire and their subjects. They constructed platforms, houses and altars on many summits and carried out sacrifices, including human sacrifices. The highest peak they are known for certain to have climbed is Llullaillaco (6,739 m). They may also have ascended the highest peak in the Andes, Aconcagua (6,962 m) as a sacrifice victim has been found at over 5,000 m on this peak.

In 1492 the ascent of Mont Aiguille was made by order of Charles VIII of France. The Humanists of the 16th century adopted a new attitude towards mountains, but the disturbed state of Europe nipped in the bud the nascent mountaineering of the Zurich school.

Leonardo da Vinci climbed to a snow-field in the neighborhood of Monte Rosa and made scientific observations.

in 1573, Francesco De Marchi reached the summit of Gran Sasso (2912m) in central Italy.

In 1642 Darby Field made the first recorded ascent of Mount Washington, then known as Agiocochook, in New Hampshire.

Konrad Gesner and Josias Simler of Zurich visited and described mountains, and made regular ascents. The use of ice axe and rope were locally invented at this time. No mountain expeditions of note are recorded in the 17th century.

Richard Pococke and William Windham's historic visit to Chamonix was made in 1741, and set the trend for visiting glaciers.

The first attempt to ascend Mont Blanc was made in 1775 by a party of natives. In 1786 Dr Michel Paccard and Jacques Balmat gained the summit for the first time. Horace-Bénédict de Saussure, the initiator of the first ascent followed next year.

The Norwegian mountain climber, Jens Esmark was the first person to ascend Snøhetta in 1798, part of the Dovrefjell range in Southern Norway. The same year he led the first expedition to Bitihorn, a small mountain in the southernmost outskirts of Jotunheimen, Norway. In 1810 he was the first person to ascend Mount Gaustatoppen in Telemark, Norway.

The Grossglockner was climbed in 1800, the Ortler in 1804, the Jungfrau in 1811, the Finsteraarhorn in 1812, and the Breithorn in 1813. Thereafter, tourists showed a tendency to climb, and the body of Alpine guides began to come into existence as a consequence.

The British scientist, Sir John Herschel, makes an ascent in 1824 where on July 23 he carries out a barometric determination of the height of Mount Etna.

Aconcagua (22,831 feet), the highest peak of the Andes was first climbed in 1897 and the Grand Teton (13,747 feet)in North America's Rocky Mountains was ascended in 1898.

The Italian Duke of the Abruzzi in 1897 made the first ascent on Mount St.Elias (18,009 feet) which stands at the boundary of Alaska and Canada and in 1906 successfully climbed Margherita in the Ruwenzori group (16,795 feet) in East Africa. In 1913, an American,Hudson Stuck ascended Mount Mckinley (20,320 feet) in Alaska, the highest peak in North America.

Citlaltépetl (5720 m in Mexico) was first climbed in 1848 by F. Maynard & G. Reynolds.

Systematic mountaineering, as a sport, is usually dated from Sir Alfred Wills's ascent of the Wetterhorn in 1854. The first ascent of Monte Rosa was made in 1855.

The Alpine Club was founded in London in 1857, and was soon imitated in most European countries. Edward Whymper's ascent of the Matterhorn in 1865 marked the close of the main period of Alpine conquest, the Golden age of alpinism, during which the craft of climbing was invented and "perfected", the body of professional guides formed and their traditions fixed.

Passing to other ranges, the exploration of the Pyrenees was concurrent with that of the Alps. The Caucasus followed, mainly owing to the initiative of D. W. Freshfield; it was first visited by exploring climbers in 1868, and most of its great peaks were climbed by 1888.

The Edelweiss Club Salzburg was founded in Salzburg in 1881, and had 3 members make the first ascent on two Eight-thousanders, Broad Peak (1957) and Dhaulagiri (1960).

Trained climbers turned their attention to the mountains of North America in 1888, when the Rev. W. S. Green made an expedition to the Selkirk Mountains. From that time exploration has gone on apace, and many English and American climbing parties have surveyed most of the highest peaks; Pikes Peak (14,110 ft) having been climbed by Mr. E. James and party in 1820, and Mt. Saint Elias (18,008 ft) by the Duke of the Abruzzi and party in 1897. The exploration of the highest Andes was begun in 1879-1880, when Whymper climbed Chimborazo and explored the mountains of Ecuador. The Cordillera between Chile and Argentina was visited by Dr. Gussfeldt in 1883, who ascended Maipo (17,270 ft) and attempted Aconcagua (22,841 ft). That peak was first climbed by the Fitzgerald expedition in 1897.

The Andes of Bolivia were first explored by Sir William Martin Conway in 1898. Chilean and Argentine expeditions revealed the structure of the southern Cordillera in the years 1885-1898. Conway visited the mountains of Tierra del Fuego.

New Zealand's Southern Alps were first visited in 1882 by the Rev. W. S. Green, and shortly afterwards a New Zealand Alpine Club was founded, and by their activities the exploration of the range was pushed forward. In 1895, Major Edward Arthur Fitzgerald, made an important journey in this range. Tom Fyfe and party climbed Aoraki/Mount Cook on Christmas Day 1894, denying Fitzgerald the first ascent. Fitzgerald was en route from Britain with Swiss guide Matthias Zurbriggen to claim the peak. So piqued at being beaten to the top of Mount Cook, he refused to climb it and concentrated on other peaks in the area. Later in the trip Zubriggen soloed Mount Cook up a ridge that now bears his name.

The first mountains of the arctic region explored were those of Spitsbergen by Sir W. M. Conway's expeditions in 1896 and 1897.

Of the high African peaks, Kilimanjaro was climbed in 1889 by Dr. Hans Meyer, Mt. Kenya in 1899 by Halford John Mackinder, and a peak of Ruwenzori by H. J. Moore in 1900. The Asiatic mountains were initially surveyed on orders of the British Empire. In 1892 Sir William Martin Conway explored the Karakoram Himalaya, and climbed a peak of In 1895 Albert F. Mummery died while attempting Nanga Parbat, while in 1899 D. W. Freshfield took an expedition to the snowy regions of Sikkim. In 1899, 1903, 1906 and 1908 Mrs Fannie Bullock Workman made ascents in the Himalayas, including one of the Nun Kun peaks (23,300 ft). A number of Gurkha sepoys were trained as expert mountaineers by Major the Hon. C. G. Bruce, and a good deal of exploration was accomplished by them. The Sierra Club was founded by John Muir in San Francisco, California in 1892.

The Rucksack Club was founded in Manchester, England in 1902.

The American Alpine Club was founded in 1902.

In 1902, the Eckenstein-Crowley Expedition, led by mountaineer Oscar Eckenstein and author and occultist Aleister Crowley, was the first to attempt to scale Chogo Ri (now known as K2 in the west). They reached before turning back due to weather and other mishaps. In 1905, Aleister Crowley led the first expedition to Kangchenjunga, the third highest mountain in the world. Four members of that party were killed in an avalanche. Some claims say they reached around before turning back, however Crowley's autobiography claims they reached about . A few Olympics in the 1920s included prizes for alpinism, but these were discontinued after World War II. The British made several attempts in the 1920s to climb Mount Everest. The first in 1921 was more of an exploratory expedition but the 1922 expedition reached before being aborted on the third summit attempt after seven porters were killed in an avalanche. The 1924 expedition saw another height record achieved but still failed to reach the summit when George Mallory and Andrew Irvine disappeared on the final attempt.

1938 saw the first ascent of the North Face of the Eiger by Andreas Heckmair, Wiggerl Vorg, Fritz Kasparek and Heinrich Harrer. This route was feted as the "last great problem of the Alps" (one of several).

The 1950s saw the first ascents of all the eight-thousanders but two, starting with Annapurna in 1950 by Maurice Herzog and Louis Lachenal. The world's highest mountain (above mean sea level), Mount Everest (8,848 m) was first climbed on May 29, 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), a siege style expedition culminating in a remarkable solo push for the summit, it's the only eight-thousander to be summited solo on the first ascent. K2 (8,611 m), 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 (8,013 m), the lowest of all the 8,000 metre peaks.
