48-579: The Cordillera Darwin is an extensive mountain range mantled by an ice field that is located in Chile . Cordillera Darwin is located in the southwestern portion of Isla Grande de Tierra del Fuego , entirely within the Chilean territory. It is part of the longest Andes range and includes the highest mountains in Tierra del Fuego , with elevations reaching over 2,000 m (6,600 ft); The ice field of

96-597: A mountain range in Central and East Asia , where Russia , China , Mongolia , and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert . It spans from about 45° to 52° N and from about 84° to 99° E. The region

144-754: A big bend, the river (600 km (370 mi) long) pierces the Katun Belki , and enters a wider valley, lying at an elevation of 600–1,100 m (2,000–3,600 ft), which it follows until it emerges from the Altai highlands to join the Biya River . Here, the two rivers merge together to form the Ob River . The next valley is that of the Charysh , which has the Korgon and Tigeretsk Range on one side and

192-531: A grotto in this glacier bursts tumultuously the Katun river. The middle and lower parts of the Bukhtarma valley have been colonized since the 18th century by runaway Russian peasants, serfs, and religious schismatics ( Raskolniks ), who created a free republic there on Chinese territory ; and after this part of the valley was annexed to Russia in 1869, it was rapidly colonized. The high valleys farther north, on

240-633: A number of well-known glaciers including the Marinelli Glacier , which is now under prolonged retreat as of 2008. In October 2011, a team of French mountaineers from the French Army's Groupe Militaire de Haute Montagne announced the first crossing of the Cordillera Darwin in a 29-day trip which included an ascent of Mount Darwin , the highest peak in the range. This Magallanes and Antártica Chilena Region location article

288-502: A system of remote mountains in central Asia that cover an area of 845,000 km (326,000 sq mi). The mountains stretch for 2,525 km (1,569 mi) from northwest to southeast. In the north of the region is the Sailughem Mountains , also known as Kolyvan Altai , which stretch northeast from 49° N and 86° E towards the western extremity of the Sayan Mountains in 51° 60' N and 89° E. Their mean elevation

336-843: A variety of rock types . Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide belt . The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera , the Aleutian Range , on through Kamchatka Peninsula , Japan , Taiwan , the Philippines , Papua New Guinea , to New Zealand . The Andes

384-489: Is 1,500–1,750 m (4,920–5,740 ft). The snow-line runs at 2,000 m (6,600 ft) on the northern side and at 2,400 m (7,900 ft) on the southern, and above it the rugged peaks tower some 1,000 m (3,300 ft) higher. Mountain passes across the range are few and difficult, the chief being the Ulan-daban at 2,827 m (9,275 ft) (or 2,879 m (9,446 ft) according to Kozlov), and

432-722: Is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system. The Alpide belt stretches 15,000 km across southern Eurasia , from Java in Maritime Southeast Asia to the Iberian Peninsula in Western Europe , including the ranges of the Himalayas , Karakoram , Hindu Kush , Alborz , Caucasus , and the Alps . The Himalayas contain the highest mountains in

Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology . They may be a mix of different orogenic expressions and terranes , for example thrust sheets , uplifted blocks , fold mountains, and volcanic landforms resulting in

528-546: Is a small herd in a nursery in the Altai Republic . Moor frogs are near bodies of water as high up as 2,000 m (6,600 ft) in the Altai mountains. The Altai mountains have retained a remarkably stable climate, changing little since the last ice age. In addition the mix of mammals has remained largely the same, with a few exceptions such as extinct mammoths, making it one of the few places on earth to retain an ice age fauna. The Altai mountains were home to

576-531: Is also a protected site. Violations of the protection status of Argali sheep and other species have been alleged, together with accusations of corruption, in the Altaigate Scandal . The incident arose from the death of several Russian VIPs in a helicopter crash early in 2009, purportedly on a poaching excursion. The Siberian Altai represents the northernmost region affected by the tectonic collision of India into Asia. Extensive fault systems run through

624-671: Is also called Uch-Sumer. The second highest peak of the range is in Mongolian part named Khüiten Peak . This massive peak reaches 4,374 m (14,350 ft). Numerous spurs, striking in all directions from the Sailughem mountains, fill up the space between that range and the lowlands of Tomsk . Such are the Chuya Belki , having an average elevation of 2,700 m (8,900 ft), with summits from 3,500–4,177 m (11,483–13,704 ft) and several glaciers on their northern slope;

672-538: Is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet (3,000 m) of mostly Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to

720-622: Is derived from underlying form * altañ "gold, golden" (compare Old Turkic 𐰞𐱃𐰆𐰣 altun "gold, golden") with coda -ñ underlying the -n & -y correspondence among cognates in different Turkic languages & dialects (e.g. qōñ ~ qoy "sheep", Qitan ~ Qitay "Khitans", etc.), as well as in Mongolian. The mountains are called Altain nuruu ( Алтайн нуруу ) in Khalkha Mongolian , altai-yin niruɣu in Chakhar Mongolian , and Altay tuular ( Алтай туулар ) in

768-531: Is drier, having been stripped of much of its moisture. Often, a rain shadow will affect the leeward side of a range. As a consequence, large mountain ranges, such as the Andes, compartmentalize continents into distinct climate regions . Mountain ranges are constantly subjected to erosional forces which work to tear them down. The basins adjacent to an eroding mountain range are then filled with sediments that are buried and turned into sedimentary rock . Erosion

816-445: Is inhabited by a sparse but ethnically diverse population, including Russians , Kazakhs , Altais , Tuvans , Mongols , and Volga Germans , though predominantly represented by indigenous ethnic minorities of semi-nomadic people. The local economy is based on bovine , sheep , horse husbandry , hunting , agriculture , forestry , and mining . The proposed Altaic language family takes its name from this mountain range. Altai

864-685: Is studded with large lakes, e.g. Uvs 720 m (2,360 ft) above sea level, Khyargas , Dorgon and Khar 1,170 m (3,840 ft), and traversed by various mountain ranges , of which the principal are the Tannu-Ola Mountains , running roughly parallel with the Sayan Mountains as far east as the Kosso-gol , and the Khan Khökhii mountains, also stretching west and east. The north western and northern slopes of

912-634: Is very difficult. The oldest known text that describes skiing is from a Chinese text that dates to the Western Han Dynasty (206 BC to 24 AD) and refers to skiers in the Altai Mountains. A vast area of 16,178 km (6,246 sq mi) , which incorporates the Altai and Katun Natural Reserves, Lake Teletskoye , Mount Belukha , and the Ukok Plateau , this area is designated as a World Heritage Site (UNESCO), entitled

1056-698: The Denisovan branch of hominids who were contemporaries of Neanderthals and of Homo sapiens (modern humans), descended from Hominids who reached Asia earlier than modern humans. The Denisova hominin , dated to 40,000 years ago, was discovered in the Denisova Cave of the Altai mountains in southern Siberia in 2008. Knowledge of the Denisovan humans derives primarily from DNA evidence and artifacts, as no complete skeletons have yet been recovered. DNA evidence has been unusually well preserved because of

1104-624: The Golden Mountains of Altai . As stated in the UNESCO description of the site, "the region represents the most complete sequence of altitudinal vegetation zones in central Siberia, from steppe, forest-steppe, mixed forest, subalpine vegetation to alpine vegetation". While making its decision, UNESCO also cited Russian Altai's importance for preservation of the globally endangered mammals, such as Snow leopard , Altai argali , and Siberian ibex that live in these mountains. The Uvs Nuur basin

1152-659: The Katun Belki , which have a mean elevation of about 3,000 m (9,800 ft) and are mostly snow-clad; the Kholzun range; the Korgon , highest point Mayak Shangina , the Talitsk and Selitsk ranges; as well as the Tigeretsk Range . Several secondary plateaus of lower elevations are also distinguished by geographers. The Valley of the Katun river begins as a wild gorge on the south-west slope of Belukha; then, after

1200-714: The Khovd basin on the north from the Irtysh basin on the south, is a true border-range, in that it rises in a steep and lofty escarpment from the Dzungarian depression (470–900 m (1,540–2,950 ft)), but descends on the north by a relatively short slope to the plateau (1,150–1,680 m (3,770–5,510 ft)) of north-western Mongolia . East of 94° E the range is continued by a double series of mountain chains, all of which exhibit less sharply marked orographical features and are at considerably lower elevations. The slopes of

1248-716: The Mithrim Montes and Doom Mons on Titan, and Tenzing Montes and Hillary Montes on Pluto. Some terrestrial planets other than Earth also exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars . Jupiter's moon Io has mountain ranges formed from tectonic processes including the Boösaule , Dorian, Hi'iaka and Euboea Montes . Altai Mountains 49°N 89°E  /  49°N 89°E  / 49; 89 The Altai Mountains ( / ɑː l ˈ t aɪ / ), also spelled Altay Mountains , are

1296-473: The Ocean Ridge forms the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi). The position of mountain ranges influences climate, such as rain or snow. When air masses move up and over mountains, the air cools, producing orographic precipitation (rain or snow). As the air descends on the leeward side, it warms again (following the adiabatic lapse rate ) and

1344-467: The Siberian ibex ( Capra sibirica ), whereas the rare argali ( Ovis ammon ) is found on more gentle slopes. Deer are represented by five species: Altai wapiti ( Cervus elaphus sibiricus ), moose ( Alces alces ), forest reindeer ( Rangifer tarandus valentinae ), Siberian musk deer ( Moschus moschiferus ), and Siberian roe deer ( Capreolus pygargus ). Moose and reindeer however, are restricted to

1392-630: The Talitsk and Baschelaksk Range (Бащелакский хребет) on the other. This, too, is very fertile. The Altai, seen from this valley, presents the most romantic scenes, including the small but deep Kolyvan Lake at an altitude of 360 m (1,180 ft), which is surrounded by fantastic granite domes and towers. Farther west the valleys of the Uba , the Ulba and the Bukhtarma open south-westwards towards

1440-479: The Altai Mountains of Siberia" from "an even larger glacial lake" than Lake Missoula, which was once thought to have been "the largest ice-dammed lake in the world". Although earthquakes are generally rare occurrences, on 27 September 2003 a very large earthquake measuring M W 7.3 occurred in the Chuya Basin area to the south of the Altai region. This earthquake and its aftershocks devastated much of

1488-532: The Bukhtarma fortress (345 m (1,132 ft)), it offers the most striking contrasts of landscape and vegetation. Its upper parts abound in glaciers, the best known of which is the Berel , which descends from the Belukha . On the northern side of the range which separates the upper Bukhtarma from the upper Katun is the Katun glacier, which after two ice-falls widen out to 700–900 m (2,300–3,000 ft). From

1536-717: The Cordillera Darwin covers an area greater than 2,300 square kilometres (890 sq mi). The Darwin Range extends in a west–east direction from the Monte Sarmiento (located in the vicinity of Magdalena Channel ) to Yendegaia Valley . It is bounded by the Almirantazgo Fjord on the north and the Beagle Channel on the south. The range is named after Charles Darwin and is the most important feature of Alberto de Agostini National Park , which includes

1584-889: The Irtysh. The lower part of the first, like the lower valley of the Charysh, is thickly populated; in the valley of the Ulba is the Riddersk mine, at the foot of the Ivanovsk Peak (2,060 m (6,760 ft)), clothed with alpine meadows. The valley of the Bukhtarma, which has a length of 320 km (200 mi), also has its origin at the foot of the Belukha and the Kuitun peaks, and as it falls some 1,500 m (4,900 ft) in about 3,000 km (1,900 mi), from an alpine plateau at an elevation of 1,900 m (6,200 ft) to

1632-487: The Sailughem Mountains are extremely steep and difficult to access. On this side lies the highest summit of the range, the double-headed Belukha , whose summits reach 4,506 m (14,783 ft) and 4,400 m (14,400 ft) respectively, and give origin to several glaciers and glaciokarst formations (30 km (12 sq mi) in aggregate area, as of 1911 ). Altaians call it Kadyn Bazhy, but

1680-464: The area, including the Kurai fault zone and the recently identified Tashanta fault zone . These fault systems are typically thrusts or right lateral strike-slip faults , some of which are tectonically active. Rock types in the mountains are typically granites and metamorphic schists , and some are highly sheared near to fault zones. Geologist Victor R. Baker "has discovered past cataclysmic floods in

1728-680: The claims includes several cave petroglyphs within the Altai Mountains in modern China that depict human figures on skis that are chasing after an ibex . According to a study published by the Australian Rock Art Research Association (AURA) in 2016, this rock art was estimated to be from between 4,000 and 5,250 years ago, which consequently meant it may be just as old or possibly older than ancient skiing rock art and artefacts located in Scandinavia. However, dating petroglyphs accurately with current technology

1776-473: The constituent chains of the system are inhabited principally by nomadic Kyrgyz . The five highest mountains of the Altai are: The Altai-Sayan ecoregion is located at the intersection of the Central Asian and Siberian faunal provinces. The Altai mountains are home to a diverse fauna, because of its different habitats, like steppes, northern taigas and alpine vegetation. Steep slopes are home to

1824-485: The east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive,

1872-567: The lake rise almost sheer to over 1,800 m (5,900 ft). From this lake issues the Biya, which joins the Katun at Biysk , and then meanders through the prairies of the north-west of the Altai. Farther north the Altai highlands are continued in the Kuznetsk district, which has a slightly different geological aspect, but belongs to the Altai system. But the Abakan River , which rises on

1920-659: The low average temperature in the Denisova caves. Neanderthal bones and tools made by Homo sapiens have also been found in the Denisova Cave, making it the only place in the world where all three hominids are known to have lived. A dog-like canid from 33,000 years ago was found in the Razboinichya Cave . DNA analysis published in 2013 affirmed that it was more closely related to modern dogs than to wolves. The Altai Mountains have been identified as being

1968-402: The northern parts also by the wolverine ( Gulo gulo ). The Tien Shan dhole ( Cuon alpinus hesperius ) (a northwestern subspecies of the Asiatic wild dog ) also lives there. Most species of the region are of Mongolian origin. The western Siberian eagle-owl can be found in the western part of the mountains. Until the 20th century, the Caspian tiger ( Panthera tigris tigris ) was found in

2016-500: The northern parts of the mountain range. The wild boar ( Sus scrofa ) is found in the lower foothills and surrounding lowlands. Until recently, the Mongolian gazelle ( Procapra gutturosa ) was found in the Russian Altai mountains, more specifically in the Chuya River steppe close to the Mongolian border. Large predators are represented by snow leopards ( Panthera uncia , syn. Uncia uncia ), wolves ( Canis lupus ), Eurasian lynx ( Lynx lynx ), and brown bears ( Ursus arctos ), in

2064-426: The point of origin of a cultural enigma termed the Seima-Turbino Phenomenon which arose during the Bronze Age around the start of the 2nd millennium BC and led to a rapid and massive migration of peoples from the region into distant parts of Europe and Asia. Some historians believe that the Altai mountain region may have been the location where skiing was born, however this remains disputed. Evidence to support

2112-516: The rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System, including the Moon , are often isolated and formed mainly by processes such as impacts, though there are examples of mountain ranges (or "Montes") somewhat similar to those on Earth. Saturn 's moon Titan and Pluto , in particular, exhibit large mountain ranges in chains composed mainly of ices rather than rock. Examples include

2160-507: The same western face of the Sailughem range, are but little known, their only visitors being Kyrgyz shepherds. Those of Bashkaus , Chulyshman , and Chulcha , all three leading to the alpine lake of Teletskoye (length, 80 km (50 mi); maximum width, 5 km (3.1 mi); elevation, 520 m (1,710 ft); area, 230.8 km (89.1 sq mi); maximum depth, 310 m (1,020 ft); mean depth, 200 m (660 ft)), are inhabited by Telengit people. The shores of

2208-433: The southern parts of the Altai mountains, where it reached Lake Zaisan and the Black Irtysh . Single individuals were also shot further north, for example close to Barnaul . Closely related to the Caspian tiger is the extant Amur tiger , which has the taxonomic name Panthera tigris altaica . The wisent was present in the Altai mountains until the Middle Ages , perhaps even until the 18th century. Today, there

2256-408: The western shoulder of the Sayan mountains, belongs to the system of the Yenisei . The Kuznetsk Ala-tau range, on the left bank of the Abakan, runs north-east into the government of Yeniseisk , while a complexus of mountains (Chukchut, Salair, Abakan) fills up the country northwards towards the Trans-Siberian Railway and westwards towards the Ob . The Ek-tagh or Mongolian Altai, which separates
