Swiss Air-Rescue (German: Schweizerische Rettungsflugwacht , French: Garde aérienne suisse de sauvetage , Italian: Guardia aerea svizzera di soccorso , Rega ) is a private, non-profit air rescue service that provides emergency medical assistance in Switzerland and Liechtenstein . Rega was founded on 27 April 1952 by Rudolf Bucher, who believed that the Swiss rescue service needed a specialized air branch. Rega mainly assists in mountain rescues, but also operates in other terrains when necessary, especially in life-threatening emergencies. Rega also provides a repatriation and medical advice service for members who experience a medical emergency while abroad and local treatment is not available.

68-558: Rega also aids alpine farmers during the summer months in rescuing livestock and retrieving dead animals. As a non-profit foundation, Rega does not receive financial assistance from any government. They are quite unusual within Europe, with the majority of their costs paid through the annual fees of private contributors (As of 2016: 3.2 million patrons, 38% of the population). In exchange, Rega does not charge its contributors for its search, rescue and repatriation costs. One other rare aspect of Rega

136-412: A rope team , particularly on large snow slopes or easier rock sections. Simultaneous climbing (or simul climbing ) is riskier but is necessary to ensure that the climbers can move quickly through what is often a very dangerous and exposed environment (e.g. rockfall on open ice fields), and complete the routes in a reasonable time. Alpine climbing can involve aid climbing , particularly if high up on

204-460: A "typical" range of rock and ice climbing grades for to each acronym: Note: A "+" (pronounced Sup for supérieur ) or a "−" (pronounced Inf for inférieur ) is placed after the acronym to indicate if a climb is at the lower or upper end of that grade (e.g., a climb slightly harder than "PD+" might be "AD−"). The term ABO for abominable is explicitly not recognized by the UIAA. The following are

272-600: A crescent shaped geographic feature of central Europe that ranges in an 800 km (500 mi) arc (curved line) from east to west and is 200 km (120 mi) in width. The mean height of the mountain peaks is 2.5 km (1.6 mi). The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble , and stretching eastward through mid and southern Switzerland. The range continues onward toward Vienna , Austria, and southeast to

340-410: A fight for the team's very survival (e.g. as extensively chronicled during the famous 1936 Eiger climbing disaster ). The derived term "alpine style" alludes to the fashion of alpine climbing to be in small fast-moving teams – or even solo – who carry all of their own equipment (e.g. no porters), and do all of the climbing (e.g. no sherpas or reserve teams laying down fixed ropes ). "Alpine-style"

408-716: A major commercial and military road between Western Europe and Italy. The pass was crossed by many troops on their way to the Italian peninsula. From Constantine I , Pepin the Short and Charlemagne to Henry IV , Napoléon and more recently the German Gebirgsjägers during World War II . Now the pass has been supplanted by the Fréjus Highway Tunnel (opened 1980) and Rail Tunnel (opened 1871). The Saint Gotthard Pass crosses from Central Switzerland to Ticino ; in 1882

476-687: A man was in 1788; the first ascent by a woman was in 1808. By the mid-1850s Swiss mountaineers had ascended most of the peaks and were eagerly sought as mountain guides. Edward Whymper reached the top of the Matterhorn in 1865 (after seven attempts), and in 1938 the last of the six great north faces of the Alps was climbed with the first ascent of the Eiger Nordwand (north face of the Eiger). Important geological concepts were established as naturalists began studying

544-450: A route, aid is needed to make progress and avoid a dangerous retreat. It can also involve multiple and complex abseils , either on the descent or in a retreat from a route. Classic alpine climbing routes often take at least a full day of climbing which necessitates the early " alpine start " (and helps to avoid the afternoon rockfalls), and may force a bivouac . It often involves traveling on glaciers and bergschrunds to get to and from

612-588: A specialist trained by the Swiss Alpine Club . In the Canton of Valais , helicopter search and rescue is carried out by Air Glaciers and Air Zermatt The name Rega was created by combining letters from the name "Swiss Air Rescue Guard" as it was written in German (Schweizerische Rettungsflugwacht), French (Garde Aérienne Suisse de Sauvetage), and Italian (Guardia Aerea Svizzera di Soccorso). The decision to change

680-582: A tunnel 1.6 km (1 mi) long was built along the route of the pass in the mid-19th century. With a summit of 2,469 m (8,100 ft), the Great St Bernard Pass is one of the highest in the Alps, crossing the Italian-Swiss border east of the Pennine Alps along the flanks of Mont Blanc. The pass was used by Napoleon Bonaparte to cross 40,000 troops in 1800. The Mont Cenis pass has been

748-629: Is sedimentary rock formed during mountain building. The Alpine orogeny occurred in ongoing cycles through to the Paleogene causing differences in folded structures, with a late-stage orogeny causing the development of the Jura Mountains . A series of tectonic events in the Triassic, Jurassic and Cretaceous periods caused different paleogeographic regions. The Alps are subdivided by different lithology (rock composition) and nappe structures according to

816-498: Is of continental European origin, above which are stacked marine sediment nappes, topped off by nappes derived from the African plate. The Matterhorn is an example of the ongoing orogeny and shows evidence of great folding. The tip of the mountain consists of gneisses from the African plate; the base of the peak, below the glaciated area, consists of European basement rock. The sequence of Tethyan marine sediments and their oceanic basement

884-608: Is sandwiched between rock derived from the African and European plates. The core regions of the Alpine orogenic belt have been folded and fractured in such a manner that erosion produced the characteristic steep vertical peaks of the Swiss Alps that rise seemingly straight out of the foreland areas. Peaks such as Mont Blanc, the Matterhorn, and high peaks in the Pennine Alps, the Briançonnais, and Hohe Tauern consist of layers of rock from

The annual Piolets d'Or are awarded for

1020-516: Is that people in distress can call for a helicopter rescue directly (phone number 1414). In case of insufficient mobile phone coverage, alpinists can also use emergency radio telephone (161.3 MHz). The head office, the Rega Centre, (home to the Rega operations center where all missions are coordinated) is a hangar located at the northeast section of Zurich Airport within the municipality of Kloten ;

1088-635: Is the opposite of expedition style (which is sometimes pejoratively called "siege style"), and is often considered a "purer" form of climbing. "Alpine style" also means being "lightly equipped" with for example no supplementary oxygen, no major tenting or overnight equipment, and limited food and fuel supplies. It also means having no fixed ropes on the route (an important safety feature of expedition-style mountaineering). While these attributes enable alpine climbers to move quickly and take advantage of good conditions and " weather windows ", it also makes alpine climbing far more dangerous. In situations where

1156-523: The Adriatic Sea and Slovenia . To the south it dips into northern Italy and to the north extends to the southern border of Bavaria in Germany. In areas like Chiasso , Switzerland, and Allgäu , Bavaria, the demarcation between the mountain range and the flatlands are clear; in other places such as Geneva , the demarcation is less clear. The Alps are found in the following countries: Austria (28.7% of

1224-892: The Colle della Maddalena , to the north. Upon reaching the Swiss border, the line of the main chain heads approximately east-northeast, a heading it follows until its end near Vienna. The northeast end of the Alpine arc, directly on the Danube , which flows into the Black Sea, is the Leopoldsberg near Vienna. In contrast, the southeastern part of the Alps ends on the Adriatic Sea in the area around Trieste towards Duino and Barcola . The Alps have been crossed for war and commerce, and by pilgrims, students and tourists. Crossing routes by road, train, or foot are known as passes , and usually consist of depressions in

1292-518: The European Alps , it is used to refer to climbing in any remote mountainous area, including in the Himalayas and Patagonia. The derived term alpine style refers to the fashion of alpine climbing to be in small lightly equipped teams who carry their equipment (e.g. no porters), and do all of the climbing (e.g. no sherpas or reserve teams). Alpinists face a wide range of serious risks in addition to

1360-502: The Gotthard Base Tunnel , was opened, which connects Erstfeld in canton of Uri with Bodio in canton of Ticino by two single tubes of 57.1 km (35.5 mi). It is the first tunnel that traverses the Alps on a flat route. From 11 December 2016, it has been part of the regular railway timetable and used hourly as standard ride between Basel / Lucerne / Zürich and Bellinzona / Lugano / Milan . The highest pass in

1428-585: The Oxford English Dictionary , the Latin Alpes might derive from a pre-Indo-European word * alb "hill"; "Albania" is a related derivation. Albania, a name not native to the region known as the country of Albania , has been used as a name for several mountainous areas across Europe. In Roman times , "Albania" was a name for the eastern Caucasus , while in the English languages "Albania" (or "Albany")

1496-733: The Pangaean supercontinent consisted of a single tectonic plate ; it broke into separate plates during the Mesozoic Era and the Tethys sea developed between Laurasia and Gondwana during the Jurassic Period. The Tethys was later squeezed between colliding plates causing the formation of mountain ranges called the Alpide belt , from Gibraltar through the Himalayas to Indonesia —a process that began at

1564-460: The Romanticists , followed by the golden age of alpinism as mountaineers began to ascend the peaks of the Alps. The Alpine region has a strong cultural identity. Traditional practices such as farming, cheesemaking, and woodworking still thrive in Alpine villages. However, the tourist industry began to grow early in the 20th century and expanded significantly after World War II, eventually becoming

For larger operations, Rega may request additional helicopters from the FOCA or the Swiss Accident Investigation Board (SAIB, German acronym SUST) (formerly Aircraft Accident Investigation Bureau ). Rega is a partner of the Swiss Air Force , which supports Rega with helicopters and personnel when necessary. For search-and-rescue flights in difficult conditions,

1768-597: The 15 km-long (9.3 mi) Saint Gotthard Railway Tunnel was opened connecting Lucerne in Switzerland, with Milan in Italy. 98 years later followed Gotthard Road Tunnel (16.9 km (10.5 mi) long) connecting the A2 motorway in Göschenen on the north side with Airolo on the south side, exactly like the railway tunnel. On 1 June 2016 the world's longest railway tunnel,

1836-651: The 20th century Robert Parker wrote a well-known work about the rock crystals of the Swiss Alps; at the same period a commission was established to control and standardize the naming of Alpine minerals. In the Miocene Epoch the mountains underwent severe erosion because of glaciation, which was noted in the mid-19th century by naturalist Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervals—a theory he formed when studying rocks near his Neuchâtel home which he believed originated to

1904-668: The 29 "four-thousanders" with at least 300 m (984 ft) of prominence. While Mont Blanc was first climbed in 1786 and the Jungfrau in 1811, most of the Alpine four-thousanders were climbed during the second half of the 19th century, notably Piz Bernina (1850), the Dom (1858), the Grand Combin (1859), the Weisshorn (1861) and the Barre des Écrins (1864); the ascent of the Matterhorn in 1865 marked

1972-522: The Air Force has a FLIR -equipped helicopter (usually Eurocopter AS332 Super Puma or Cougar) on call. The Air Force continually monitors the airspace and directs emergency signals immediately to Rega. Aircraft equipment of the Swiss Air Force is used to gain a rapid and precise location of an emergency signal that is transmitted to the Rega helicopter early in an emergency mission. Rega also has access to

Alpinist Alpine climbing ( German : Alpinklettern ) is a type of mountaineering that uses any of a broad range of advanced climbing skills, including rock climbing , ice climbing , and/or mixed climbing , to summit typically large routes (e.g. multi-pitch or big wall ) in an alpine environment. While alpine climbing began in

2108-481: The Alpine region. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments. Alpine crystals have been studied and collected for hundreds of years and began to be classified in the 18th century. Leonhard Euler studied the shapes of crystals, and by the 19th-century crystal hunting was common in Alpine regions. David Friedrich Wiser amassed a collection of 8000 crystals that he studied and documented. In

2176-689: The Alps are difficult to quantify and likely to vary significantly in space and time. The Alps are a source of minerals that have been mined for thousands of years. In the 8th to 6th centuries, BC during the Hallstatt culture , Celtic tribes mined copper; later the Romans mined gold for coins in the Bad Gastein area. Erzberg in Styria furnishes high-quality iron ore for the steel industry. Crystals, such as cinnabar , amethyst , and quartz , are found throughout much of

2244-754: The Alps goes back to the Palaeolithic era. A mummified man ("Ötzi") , determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established. Hannibal notably crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800, Napoleon crossed one of the mountain passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, and artists, in particular,

2312-762: The Austroalpine peaks underwent an event in the Cretaceous Period, the two areas show distinct differences in nappe formations. Flysch deposits in the Southern Alps of Lombardy probably occurred in the Cretaceous or later. Peaks in France, Italy and Switzerland lie in the "Houillière zone", which consists of basement with sediments from the Mesozoic Era. High "massifs" with external sedimentary cover are more common in

2380-509: The Eastern and South-Western Alps. The underlying mechanisms that jointly drive the present-day uplift pattern are the isostatic rebound due to the melting of the last glacial maximum ice-cap or long-term erosion, detachment of the Western Alpine subducting slab, mantle convection as well as ongoing horizontal convergence between Africa and Europe, but their relative contributions to the uplift of

2448-649: The French–Italian border, and at 4,809 m (15,778 ft) is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than 4,000 m (13,000 ft) . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation levels vary greatly and climatic conditions consist of distinct zones. Wildlife such as ibex live in the higher peaks to elevations of 3,400 m (11,155 ft), and plants such as edelweiss grow in rocky areas in lower elevations as well as in higher elevations. Evidence of human habitation in

2516-619: The Greek goddess Alphito , whose name is related to alphita , the "white flour"; alphos , a dull white leprosy; and finally the Proto-Indo-European word *albʰós . Similarly, the river god Alpheus is also supposed to derive from the Greek alphos and means whitish. In his commentary on the Aeneid of Virgil , the late fourth-century grammarian Maurus Servius Honoratus says that all high mountains are called Alpes by Celts. According to

2584-591: The Western Alps and were affected by Neogene Period thin-skinned thrusting whereas the Eastern Alps have comparatively few high peaked massifs. Similarly the peaks in eastern Switzerland extending to western Austria (Helvetic nappes) consist of thin-skinned sedimentary folding that detached from former basement rock. In simple terms, the structure of the Alps consists of layers of rock of European, African, and oceanic (Tethyan) origin. The bottom nappe structure

2652-672: The alps is the Col de l'Iseran in Savoy (France) at 2,770 m (9,088 ft), followed by the Stelvio Pass in northern Italy at 2,756 m (9,042 ft); the road was built in the 1820s. The Union Internationale des Associations d'Alpinisme (UIAA) has defined a list of 82 "official" Alpine summits that reach at least 4,000 m (13,123 ft). The list includes not only mountains, but also subpeaks with little prominence that are considered important mountaineering objectives. Below are listed

2720-405: The best achievements in alpine climbing. Alpine climbing involves small unsupported teams tackling large multi-pitch (or big wall ) routes that can involve various combinations of rock climbing , ice climbing , and mixed climbing , in alpine-type mountain environments. Alpine routes are often long and require a full day of climbing or even several days. Because of the length of the routes, and

2788-852: The central and western portions. The variances in nomenclature in the region spanned by the Alps make classification of the mountains and subregions difficult, but a general classification is that of the Eastern Alps and Western Alps with the divide between the two occurring in eastern Switzerland according to geologist Stefan Schmid, near the Splügen Pass . The highest peaks of the Western Alps and Eastern Alps, respectively, are Mont Blanc, at 4,810 m (15,780 ft), and Piz Bernina , at 4,049 m (13,284 ft). The second-highest major peaks are Monte Rosa , at 4,634 m (15,203 ft), and Ortler , at 3,905 m (12,810 ft), respectively. A series of lower mountain ranges run parallel to

2856-462: The danger of alpine environments (e.g. rockfall, avalanche, altitude, weather, etc.), alpine climbers (or "alpinists") typically try routes that are well within their technical rock, ice, or mixed climbing capabilities. While parts of an alpine route will involve a lead climber tackling difficult rock, ice, or mixed sections while being belayed by a stationary second climber below, parts will involve both climbers moving simultaneously together as

2924-497: The diverse range of climbing techniques required on major alpine routes, and the harsh conditions encountered. Alpinists face a number of additional risks to the risks of rock climbing, ice climbing, and mixed climbing, making it one of the most dangerous forms of climbing. In 2019, Francis Sanzaro writing in the New York Times said of modern alpinism: "The routes are becoming more technically demanding, in more remote areas, and

2992-424: The dominant industry by the end of the century. The Winter Olympic Games have been hosted in the Swiss, French, Italian, Austrian and German Alps. As of 2010, the region is home to 14 million people and has 120 million annual visitors. The English word Alps comes from the Latin Alpes . The Latin word Alpes could possibly come from the adjective albus ("white"), or could possibly come from

3060-553: The end of the Mesozoic and continues into the present. The formation of the Alps was a segment of this orogenic process, caused by the collision between the African and the Eurasian plates that began in the late Cretaceous Period. Under extreme compressive stresses and pressure, marine sedimentary rocks were uplifted, forming characteristic recumbent folds , and thrust faults . As

3128-495: The end of the golden age of alpinism . Karl Blodig (1859–1956) was among the first to successfully climb all the major 4,000 m peaks. He completed his series of ascents in 1911. Many of the big Alpine three-thousanders were climbed in the early 19th century, notably the Grossglockner (1800) and the Ortler (1804), although some of them were climbed only much later, such at Mont Pelvoux (1848), Monte Viso (1861) and La Meije (1877). The first British Mont Blanc ascent by

3196-443: The habitually unstable high-altitude weather turns, alpine climbers will not have the provisions to "sit out" the storm, and will not have the fixed ropes in place to retreat safely and quickly; such forced retreats in poor conditions are dangerous. While alpine climbers are "lightly equipped" due to the fact that they must carry all of their equipment while climbing, the range of climbing equipment needed can be considerable due to

3264-404: The hangar has direct access to the runways of the airport. All Rega helicopters carry a crew of three: a pilot, an emergency physician, and a paramedic who is also trained to assist the pilot for radio communication, navigation, terrain/object avoidance, and winch operations. In some situations, such as evacuating cable cars or retrieving injured climbers from a rock face, the crew also consists of

3332-431: The inclination of the main snow slopes encountered (e.g. 50–60 degrees), as these are often not graded ice climbs, but contribute significantly to the overall risk. The most widely used "overall" grades are the acronyms of the UIAA Scale of Overall Difficulty , also known as the International French Adjectival System (IFAS). The UIAA warns against aligning their acronyms with equivalent rock and ice climbing grades, as

3400-407: The main chain of the Alps, including the French Prealps in France and the Jura Mountains in Switzerland and France. The secondary chain of the Alps follows the watershed from the Mediterranean Sea to the Wienerwald , passing over many of the highest and most well-known peaks in the Alps. From the Colle di Cadibona to Col de Tende it runs westwards, before turning to the northwest and then, near

3468-455: The method of "light and fast" — minimal gear, no fixed ropes, doing the route in a single push — is now regarded as the best style. These trends, and others, have made the sport of alpine climbing very, very dangerous". In 2021, the New York Times called the Piolets d'Or, alpine climbing's most important award, "A Climbing Award That May Be a Winner’s Last", due to the number of fatalities of past winners. Additional risks faced by alpinists to

3536-598: The most notable milestones in alpine climbing (and latterly, alpine-style climbing as applied worldwide): A number of notable climbing films have been made about alpine climbing (and alpine climbing routes), including: Alps The Alps ( / æ l p s / ) are one of the highest and most extensive mountain ranges in Europe , stretching approximately 1,200 km (750 mi) across eight Alpine countries (from west to east): Monaco , France , Switzerland , Italy , Liechtenstein , Germany , Austria and Slovenia . The Alpine arch extends from Nice on

3604-419: The mountains in which a valley leads from the plains and hilly pre-mountainous zones. In the medieval period hospices were established by religious orders at the summits of many of the main passes. The most important passes are the Col de l'Iseran (the highest), the Col Agnel , the Brenner Pass , the Mont-Cenis , the Great St. Bernard Pass , the Col de Tende , the Gotthard Pass , the Semmering Pass ,

3672-456: The name was made in 1979, to create a uniform and more concise name for speakers of the three languages. Ursula Bühler Hedinger , first woman from Switzerland to hold a license to fly a jet and the first Swiss female flight instructor flew for REGA for over 25 years. Rega work closely with several organizations and emergency services including the police, fire and ambulance services. It assists in rescue efforts related to road accidents with

3740-419: The objective dangers can vary dramatically on routes with similar rock and ice climbing grades. For example, the famous 1,800-metre Eiger North Face 1938 Heckmair Route is graded ED2 even though the rock climbing is graded UIAA V− and the ice climbing is only at 60 degrees (i.e. both typically a D grade), due to the exceptional length and danger of the route. In spite of this, attempts have been made to ascribe

3808-407: The orogenic events that affected them. The geological subdivision differentiates the Western, Eastern Alps, and Southern Alps: the Helveticum in the north, the Penninicum and Austroalpine system in the centre and, south of the Periadriatic Seam, the Southern Alpine system . According to geologist Stefan Schmid, because the Western Alps underwent a metamorphic event in the Cenozoic Era while

3876-454: The range's area), Italy (27.2%), France (21.4%), Switzerland (13.2%), Germany (5.8%), Slovenia (3.6%), Liechtenstein (0.08%) and Monaco (0.001%). The highest portion of the range is divided by the glacial trough of the Rhône valley, from Mont Blanc to the Matterhorn and Monte Rosa on the southern side, and the Bernese Alps on the northern. The peaks in the easterly portion of the range, in Austria and Slovenia, are smaller than those in

3944-456: The remote setting. Due to the scale of the routes, alpine climbers need to be able to move together for speed (e.g. simul climbing or as rope teams ), which is another source of specific risk. The first "golden age" of modern alpine climbing was the first free ascents –in summer, in winter, and as solo –of the great north faces of the Alps by pioneers such as Walter Bonatti , Riccardo Cassin and Gaston Rebuffat . The subsequent era, which

4012-413: The rising peaks underwent erosion, a layer of marine flysch sediments was deposited in the foreland basin , and the sediments became involved in younger folds as the orogeny progressed. Coarse sediments from the continual uplift and erosion were later deposited in foreland areas north of the Alps. These regions in Switzerland and Bavaria are well-developed, containing classic examples of flysch , which

4080-492: The risks of rock climbing, ice climbing, and mixed climbing, are: Due to the complexity of routes in alpine climbing, the "overall" grade denotes the general level of seriousness of the route to which is added additional specific grade(s) for any rock climbing (usually the French , American , or UIAA grades for free climbing , and the A-grade for aid climbing ), ice climbing (the WI-grade ), and mixed climbing (the M-grade ) involved. In addition, alpine grades will quote

4148-408: The rock formations of the Alps in the 18th century. In the mid-19th century, the now-defunct idea of geosynclines was used to explain the presence of "folded" mountain chains. This theory was replaced in the mid-20th century by the theory of plate tectonics . The formation of the Alps (the Alpine orogeny ) was an episodic process that began about 300 million years ago. In the Paleozoic Era

4216-450: The route (and in the dark for "alpine starts"). Due to the greater complexity and risks of alpine climbing, alpinists need to be much more familiar with and confident in each team member's abilities and skill level. Alpine climbing involves exercising judgment and decision-making to adapt to the constantly changing alpine weather and route conditions (e.g. changing snow and ice levels), and where good initial progress can quickly turn into

4284-419: The specific risks of rock, ice, and mixed climbing. This includes the risks of rockfalls (common with rock faces in alpine environments), avalanches (especially in couloirs ), seracs and crevasses, violent storms hitting climbers on exposed mountain faces, altitude effects (dehydration, edema , frostbite ), complex navigation and route finding, long abseils , and the difficulty of rescue and/or retreat due to

4352-555: The summer months and where huts and hay barns can be found, sometimes constituting tiny hamlets. Therefore, the term "the Alps", as a reference to the mountains, is a misnomer. The term for the mountain peaks varies by nation and language: words such as Horn , Kogel , Kopf , Gipfel , Spitze , Stock , and Berg are used in German-speaking regions; Mont , Pic , Tête , Pointe , Dent , Roche , and Aiguille in French-speaking regions; and Monte , Picco , Corno , Punta , Pizzo , or Cima in Italian-speaking regions. The Alps are

4420-432: The various orogenies including exposures of basement rock. Due to the ever-present geologic instability, earthquakes continue in the Alps to this day. Typically, the largest earthquakes in the alps have been between magnitude 6 and 7 on the Richter scale. Geodetic measurements show ongoing topographic uplift at rates of up to about 2.5 mm per year in the North, Western and Central Alps, and at ~1 mm per year in

4488-415: The west in the Bernese Oberland. Because of his work he came to be known as the "father of the ice-age concept" although other naturalists before him put forth similar ideas. Agassiz studied glacier movement in the 1840s at the Unteraar Glacier where he found the glacier moved 100 m (328 ft) per year, more rapidly in the middle than at the edges. His work was continued by other scientists and now

The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn . Mont Blanc spans

In modern languages the term alp , alm , albe or alpe refers to a grazing pastures in the alpine regions below the glaciers, not the peaks. An alp refers to a high mountain pasture, typically near or above the tree line , where cows and other livestock are taken to be grazed during
