context_page_description: The Altai Mountains, also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia, and Kazakhstan come together, 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 is inhabited by a sparse but ethnically diverse population, including Russians, Kazakhs, Altais, and Mongolians. The local economy is based on bovine, sheep, and horse husbandry, agriculture, forestry, and mining. The now-disputed Altaic language family takes its name from this mountain range.
context_section_description: 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 is 1,500 to 1,750 m. The snow-line runs at 2,000 m on the northern side and at 2,400 m on the southern, and above it the rugged peaks tower some 1,000 m higher. Mountain passes across the range are few and difficult, the chief being the Ulan-daban at 2,827 m (2,879 m according to Kozlov), and the Chapchan-daban, at 3,217 m, in the south and north respectively. On the east and southeast this range is flanked by the great plateau of Mongolia, the transition being effected gradually by means of several minor plateaus, such as Ukok (2,380 m) with Pazyryk Valley, Chuya (1,830 m), Kendykty (2,500 m), Kak (2,520 m), (2,590 m), and (2,410 m).
  This region is studded with large lakes, e.g. Uvs 720 m above sea level, Khyargas, Dorgon and Khar 1,170 m, 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 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 and 4,440 m respectively, and give origin to several glaciers (30 square kilometers in aggregate area, as of 1911). Altaians call it Kadyn Bazhy, but is also called Uch-Sumer.
  The second highest peak of the range is in Mongolian part named Khüiten Peak. This massive peak reaches 4374 m. 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 Alps, having an average elevation of 2,700 m, with summits from 3,500 to 3,700 m, and at least ten glaciers on their northern slope; the Katun Alps, which have a mean elevation of about 3,000 m and are mostly snow-clad; the Kholzun range; the Korgon 1,900 to 2,300 m, Talitskand Selitsk ranges; the Tigeretsk Alps.
  Several secondary plateaus of lower elevations are also distinguished by geographers, The Katun Valley begins as a wild gorge on the south-west slope of Belukha; then, after a big bend, the river (600 km long) pierces the Katun Alps, and enters a wider valley, lying at an elevation of 600 to 1,100 m, which it follows until it emerges from the Altai highlands to join the Biya in a most picturesque region. The Katun and the Biya together form the Ob.
  The next valley is that of the Charysh, which has the Korgon and Tigeretsk Alps on one side and the Talitsk and Bashalatsk Alps 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 (altitude 360 m), 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 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), clothed with alpine meadows. The valley of the Bukhtarma, which has a length of 320 km, also has its origin at the foot of the Belukha and the Kuitun peaks, and as it falls some 1,500 m in about 300 km, from an alpine plateau at an elevation of 1,900 m to the Bukhtarma fortress (345 m), 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 comes down from the Byelukha. 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 widens out to 700 to 900 metres. From 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 Ru
