Mountaineering is the sport, hobby or profession of walking, hiking, trekking and climbing up mountains. It is also sometimes known as alpinism, particularly in Europe. It may be said to consist of three aspects: rock-craft, snow-craft and skiing, depending on whether the route chosen is over rock, snow or ice. All require great athletic and technical ability, and experience is also a very important part of the latter.

[edit] Technique

[edit] Snow

Snowshoes can be used to walk through deep snow approaching the mountain or on lesser slopes up the mountain. Skis can be used when conditions allow, and can be a form of the sport by itself, called Ski Mountaineering. Crampons can be used on hard snow (neve) and ice.

[edit] Glaciers

When traveling 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.

[edit] Ice

Multiple methods are used to safely travel over ice. If the terrain is steep but not vertical protection in the form of pickets or ice screws can be driven into the snow or ice and attached to the rope by the lead climber. Each climber on the team must clip past the anchor, and the last climber picks up the picket. This allows for safety should the entire team be taken off their feet. This technique is known as Simul-climbing.

If the terrain becomes vertical then standard ice climbing techniques are used.

[edit] 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 is very unpredictable. Tall mountains require many days of camping on the mountain.

[edit] Bivy

A bivy or Bivouac is simply getting a sleeping bag and Bivouac sack and laying down to sleep. Many times small half sheltered areas like cracks in rocks or simply a trench dug in the snow are used to provide a basic means of shelter as well. This technique is performed by most people only in cases of emergency, however in good weather this can be pleasant. Some climbers steadfastly committed to Alpine Style climbing plan on bivying in order to save the weight of a tent when snow conditions are not suitable for a snow cave.

[edit] Tent

Tents are the most common form of shelter used on the mountain. A four season tent is required for any camp high in the mountains. Many climbers do not use tents at high altitudes unless the snow conditions do not allow for snow caving. One of the downsides to tenting is that storm winds can be very unnerving and can cause the tent to collapse, however modern mountaineering tents are usually tested for wind speeds up to 125mph. Even so, very intense flapping of the tent fabric can hinder sleep and raise doubts about the security of the shelter in windy conditions.

[edit] Snow cave

Snow caves are the preferred way for many climbers to shelter high on the mountain. Unlike tents snow caves are silent and are actually much warmer than a tent. A correctly made snow cave will hover around freezing, which relative to outside temperatures can be very warm. Igloos are used by some climbers, but are deceptively difficult to build and require specific snow conditions.

[edit] Hazards

The craft of climbing has been developed to avoid three main types of danger: the danger of things falling on the climber (objective danger), the danger of the climber falling and inclement weather. The things that may fall include rocks, ice, snow, other climbers or their gear; the mountaineer may fall from rocks, ice or snow, or into a crevasse. In all, there are eight chief dangers: falling rocks, falling ice, snow-avalanches, falls,the climber falling, falls from ice slopes, falls down snow slopes, falls into crevasses and dangers from weather. To select and follow a route using one's skills and experience to mitigate these dangers is to exercise the climber's craft.

[edit] 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 are generally 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 direct sun exposure may easily dislodge these rocks. Local experience is a valuable help on determining typical rockfall on such routes.

The direction of the dip of rock strata often 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 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 Himalaya). It is vital to avoid camping in their possible line of fall.

[edit] 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 rockfaces, 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, and their debris seldom goes far. 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.

[edit] Avalanches

Main article: Avalanche

The avalanche is the most underestimated danger in the mountains. People generally think that they will be able to recognise the hazards and survive being caught. The truth is a somewhat different story. Every year, 120 - 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.[citation needed] 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 seldom is an avalanche to prove 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 two types of avalanche:

  1. The slab avalanche: This type of avalanche occurs when a plate of snow breaks loose and starts sliding down; these are the largest and most dangerous.
    1. Hard slab avalanche - 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.
    2. Soft slab avalanche - formed again by a cohesive layer of snow bonded together, the slab tends to break up more easily.
  2. The 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 have a moral responsibility to always carry:

  1. avalanche beacons
  2. probes
  3. shovels (retrieving victims with a shovel instead of your hands is five times faster)

and to have had avalanche training! Paradoxically, 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.

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.

[edit] Falls from rocks

The skill of a rock climber is shown by one's choice of handhold and foothold, and his adhesion to those one has chosen. Much depends on a correct estimate of the firmness of the rock where weight is to be thrown upon 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 start loose stones on to the heads of 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 be 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 for foothold an ice axe propped up by others. 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.

[edit] 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 reduce 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 located 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 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 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 deciding on the advisability of advancing 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.

[edit] 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.

[edit] 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 which are attracted to the highest points on the ground. If a climber happens to be standing on or near the summit, they may now in fact be the highest point. 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 often begin ascents "alpine style"; 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.

[edit] 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 acclimatize 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 acclimatize, 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-meter peaks (including Everest) without oxygen, almost always with a carefully planned program of acclimatization.

In 2005, researcher and mountaineer John Semple established that above-average ozone concentrations on the Tibetan plateau may pose an additional risk to climbers.[1]

[edit] Locations

Mountaineering has become a popular sport throughout the world. In Europe the sport largely originated in the Alps, and is still immensely popular here. Other notable mountain ranges frequented by climbers include the Caucasus, the Pyrenees and the Tatra mountains. In North America climbers frequent the Rockies and Sierra Nevada of California, the Cascades of Washington 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, 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 popular mountaineering areas of more local interest include the Southern Alps of New Zealand, the Japanese Alps the Scottish Highlands and the mountains of Scandinavia.

[edit] History

  • Though it is unknown whether his intention was to reach a summit, Ötzi ascended at least 3,000 m in the Alps about 5300 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 (5426 m in Mexico) was reported in 1289 by members of a local tribe (Tecanuapas)
  • 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).[1] His account of the trip was composed later as a letter to his friend Francesco Dionigi. Subsequently, April 26, 1336 came to be regarded as the "birthday of alpinism", and Petrarch (Petrarca alpinista) as the "father of alpinism". However, some believe the account to have been a fictional device in an autobiographical reflection; it is not known if any climb actually occurred.[citation needed]
  • The Rochemelon (3,538 m) in the Italian Alps was climbed in 1358.
  • In the late 1400's and early 1500's 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 6739m. They probably also ascended the highest peak in the Andes, Aconcagua 6962m as a sacrifice victim has been found at over 5000m 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 the Val Sesia and made scientific observations.
  • 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.
  • In 1744 the Titus was climbed, the first true ascent of a snow-mountain.
  • 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 Mountain in 1798, part of the Jotunheimen Range in Southern Norway. The same year he lead 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 Jungfrau was climbed 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.
  • Citlatépetl (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, 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 2 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 (18,024 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 (17,752 ft.) and attempted Aconcagua (23,393 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 Spitzbergen 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 1889 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 23,000 ft. 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 Rucksack Club was founded in Manchester, England in 1902.
  • The American Alpine Club was founded in 1902.
  • In 1902, the Eckenstein-Crowley Expedition, lead by mountaineer Oscar Eckenstein and occultist Aleister Crowley, was the first to attempt to scale Chogo Ri (now known as K2 in the west). They reached 22,000 feet before turning back due to weather and other mishaps.
  • In 1905, Aleister Crowley led the first expedition to Kanchenjunga, the third highest mountain in the world. Four members of that party were killed in an avalanche. Some claims say they reached around 21,300 feet before turning back, however Crowley's autobiography claims they reached about 25,000 feet.
  • 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 (8,850m) 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 (8,125m), a remarkable solo climb, the only eight-thousander to be solo'd on the first ascent. K2 (8,611m), the second highest peak in the world was first scaled in 1954. In 1964, the final eight-thousander to be climbed was Shishapangma (8,013m), the lowest of all the 8,000 metre peaks.
