61-729: An Alpine river in character, its source lies in the Trenta Valley in the Julian Alps in northwestern Slovenia, at an elevation of 876 metres (2,874 ft). The river runs past the towns of Bovec , Kobarid , Tolmin , Kanal ob Soči , Nova Gorica (where it is crossed by the Solkan Bridge ), and Gorizia , entering the Adriatic Sea close to the town of Monfalcone . It has a nival-pluvial regime in its upper course and pluvial-nival in its lower course. Prior to

122-611: 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

183-519: A flumine Isontio (1028), in Lisonçum (1261), an die Ysnicz (1401), and an der Snicz (ca. 1440). The Slovene name Soča is derived from the form *Sǫťa , which was borrowed from Latin (and Romance) Sontius . In turn, this is probably based on the substrate name *Aisontia , presumably derived from the PIE root * Hei̯s- 'swift, rushing', referring to a quickly moving river. Another possible origin

244-743: 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

305-708: 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

366-722: A permanent laboratory exists inside a glacier under the Jungfraujoch , devoted exclusively to the study of Alpine glaciers. Battles of the Isonzo 1916 1917 1918 White War (1915–1918) The Battles of the Isonzo (known as the Isonzo Front by historians, Slovene : soška fronta ) were a series of twelve battles between the Austro-Hungarian and Italian armies in World War I mostly on

427-708: A staunch proponent of the frontal assault who claimed the Western Front proved the ineffectiveness of machine guns , initially planned breaking onto the Slovenian plateau, taking Ljubljana and threatening Vienna . The area between the northernmost part of the Adriatic Sea and the sources of the Isonzo River thus became the scene of twelve successive battles. . As a result, the Austro-Hungarians were forced to move some of their forces from

488-604: 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

549-646: 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

610-577: Is native to rivers of the northern Adriatic basin, and it lives in the upper course of the river. This species is endangered due to the introduction of other non-indigenous trout species sometime between World War I and World War II. The Soca Valley is a popular tourist destination due to its numerous natural attractions, including the Big Soča Gorge ( Velika korita Soče ), the Little Soča Gorge ( Mala korita Soče ), Kozjak Falls, Virje Falls, and

671-503: 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

732-624: 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

793-581: 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

854-630: Is the pre-Romance root * ai̯s- 'water, river'. The present course of the river is the result of several dramatic changes that occurred during the past 2,000 years. According to the Roman historian Strabo , the river named Aesontius, which in Roman times flowed past Aquileia to the Adriatic Sea, was essentially the Natisone and Torre River system. In 585, a landslide cut off the upper part of

915-474: 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

976-915: 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

1037-660: The First World War , the river ran parallel to the border between Kingdom of Italy and the Austro-Hungarian Empire . During World War I, it was the scene of bitter fighting between the two countries, culminating in the Battle of Caporetto in October and November 1917. The river was recorded in antiquity as Aesontius , Sontius , and Isontius . Later attestations include super Sontium (in 507–11),

1098-511: 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

1159-607: 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")

1220-764: 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

1281-580: The Pannonian Basin . 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 the French–Italian border, and at 4,809 m (15,778 ft)

1342-466: 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

1403-736: The Simplon Pass , and the Stelvio Pass . Crossing the Italian-Austrian border, the Brenner Pass separates the Ötztal Alps and Zillertal Alps and has been in use as a trading route since the 14th century. The lowest of the Alpine passes at 985 m (3,232 ft), the Semmering crosses from Lower Austria to Styria ; since the 12th century when a hospice was built there, it has seen continuous use. A railroad with

1464-532: The Soča (Isonzo) was the only practical area for Italian military operations during the war. The Austro-Hungarians had fortified the mountains ahead of the Italians' entry into the war on 23 May 1915. Italian Chief of Staff Luigi Cadorna judged that Italian gains (from Gorizia to Trieste ) were most feasible at the coastal plain east of the lower end of the Soča (Isonzo) River. Cadorna had not expected operations in

1525-711: The Tolmin Gorges ( Tolminska korita ). The valley was the stage of major military operations including the twelve battles of the Isonzo on the Italian front in World War I between May 1915 and November 1917, in which over half a million Austro-Hungarian and Italian soldiers lost their lives. The Isonzo campaign comprised the following battles: 45°59′40″N 13°38′29″E  /  45.99444°N 13.64139°E  / 45.99444; 13.64139 Alps The Alps ( / æ l p s / ) are one of

1586-665: The Vipava Valley and the relatively low north-eastern edge of the Postojna Gate to Inner Carniola and Ljubljana. Italian troops did not reach the port of Trieste , the Italian General Luigi Cadorna's initial target, until after the Armistice . With the rest of the mountainous 640-kilometre (400 mi) length of the front being almost everywhere dominated by Austro-Hungarian forces,

1647-615: 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,

1708-664: 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

1769-691: 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

1830-486: 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

1891-708: 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

1952-771: 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,

2013-434: 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

2074-436: The Eastern Front and a war in the mountains around the Isonzo River began. The 138 kilometres (86 mi) long Soča River at the time ran entirely inside Austria-Hungary in parallel to the border with Italy, from the Vršič pass in the Julian Alps to the Adriatic Sea , widening dramatically a few kilometers north of Gorizia , thus opening a narrow corridor between Northern Italy and Central Europe, which goes through

2135-402: 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

2196-462: 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

2257-401: The Isonzo now discharges into the Adriatic Sea. The former estuary (of the Aesontius, and the early Isonzo) in the newly formed lagoon of Grado became an independent coastal rivulet. Due to its emerald -green water, the river is marketed as "The Emerald Beauty." It is said to be one of the rare rivers in the world that retain such a colour throughout their length. Giuseppe Ungaretti , one of

2318-422: The Isonzo sector to be easy. He was well aware that the river was prone to flooding—and indeed there were record rainfalls during 1914–1918. Further, when attacking further north the Italian army was faced with something of a dilemma: in order to cross the Isonzo safely it needed to neutralise the Austro-Hungarian defenders on the mountains above, yet to neutralise these forces the Italian forces needed first to cross

2379-437: The Natisone riverbed, causing its avulsion and subsequent stream capture by the Bontius River. The original subterranean discharge of the Bontius into the Timavo River became obstructed, and another avulsion returned the new watercourse into the bed of the lower Natisone. During the next centuries the estuary of this new river—the Soča—moved eastward until it captured the short coastal Sdobba River, through which

2440-601: The Soča River. Austro-Hungarian losses, while by no means as numerous, were nevertheless high at around 200,000 (of an overall total of around 1.2 million casualties). More than 30,000 casualties were ethnic Slovenes, the majority of them being drafted into the Austro-Hungarian Army , while Slovene civilian inhabitants from the Gorizia and Gradisca region also suffered in many thousands because they were resettled in refugee camps where Slovene refugees were treated as state enemies in Italian refugee camps, where thousands died of malnutrition. With almost continuous combat in

2501-481: 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

2562-525: 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

2623-408: The area, the precise number of battles forming the Isonzo campaign is debatable. Some historians have assigned distinct names to a couple of the Isonzo struggles, most notably at Kobarid ( Caporetto , Karfreit ) in October 1917, which would otherwise form the Twelfth Battle of the Isonzo. The fact that the battles were always named after the Isonzo River, even in Italy, was considered by some

2684-744: 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

2745-424: 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

2806-404: 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

2867-495: 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

2928-411: The greatest Italian poets, describes the Isonzo in the poem "The Rivers". The river inspired the poet Simon Gregorčič to write his best-known poem Soči ( To the Soča ), one of the masterpieces of Slovene poetry. This region served as a location for the 2008 Disney film Chronicles of Narnia: Prince Caspian . The river is also well known for the marble trout ( Salmo marmoratus ); this species

2989-402: 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 the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of

3050-407: 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

3111-419: 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 ,

3172-407: 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

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

3294-413: 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

3355-423: The river. Despite the huge effort and resources poured into the continuing Isonzo struggle, the results were invariably disappointing and without real tactical merit, particularly given the geographical difficulties that were inherent in the campaign. Cumulative casualties of the numerous battles of the Isonzo were enormous. Half of the entire Italian war death total — some 300,000 of 600,000 — were suffered along

3416-408: 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

3477-555: 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

3538-423: The territory of present-day Slovenia , and the remainder in Italy along the Isonzo River on the eastern sector of the Italian Front between June 1915 and November 1917. In April 1915, in the secret Treaty of London , Italy was promised by the Allies some of the territories of Austro-Hungarian Empire which were mainly inhabited by ethnic Slovenes, Croats and Austrian Germans. Italian commander Luigi Cadorna ,

3599-432: 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

3660-415: 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

3721-432: Was occasionally used as a name for Scotland , although it is more likely derived from the Latin word albus , the colour white. 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
