ALTAI (in Mongolian Altain-ula, the " Mountains of See also:Gold ")  , a See also:term used in See also:Asiatic See also:geography with various significations . The See also:Altai region, in See also:West See also:Siberia and See also:Mongolia, is similar in See also:character to See also:Switzerland, but covers a very much greater See also:area . It extends from the See also:river Irtysh and the Dzungarian depression (46°-47° N.) northwards to the Siberian railway and to the Sayan mountains . The backbone of the region is the Sailughem or Silyughema mountains, also known as Kolyvan Altai, which stretch See also:north-eastwards from 490 N. and 86° E. towards the western extremity of the Sayan mountains in 51° 6o' N. and 89° E . Their mean See also:elevation is 5000—5500 ft . The See also:snow-See also:line runs at 6700 ft. on the See also:northern versant and at 7800 ft. on the See also:southern, and above it the rugged peaks See also:tower up some 3200 ft. more . Passes across the range are few and difficult, the See also:chief being the See also:Ulan-daban at 9275 ft . (9445 ft. according to See also:Kozlov), and the Chapchan-daban, at 10,555 ft., in the See also:south and north respectively . On the See also:east and south-east this range is flanked by the See also:great See also:plateau of Mongolia, the transition being effected gradually by means of several See also:minor plateaus, such as Ukok (7800 ft.), Chuya (6000 ft.), Kendykty (8200 ft.), Kak (8270 ft.), Suok (8500 ft.), and Juvlu-kul (7900 ft.) . This region, which is not accurately known, is studded with large lakes, i.e . Ubsa-nor (2370 ft. above See also:sea-level), See also:Kirghiz-nor, See also:Durga-nor and See also:Kobdo-nor (3840 ft.), and traversed by various See also:mountain ranges, of which the See also:principal are the Tannu-ola, See also:running roughly parallel with the Sayan mountains as far east as the Kosso-gol (See also:loo°–1o1° E. See also:long.), and the See also:Khan-khu mountains, also stretching west and east . The range of the Altai proper, known also as the Ek-tagh, Mongolian Altai, Great Altai and Southern Altai, likewise extend in two twin parallel chains eastwards as far as 990, if not farther .

The Ek-tagh or Mongolian Altai, which separates the Kobdo See also:

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 (1550 to 3000 ft.), but descends on the north by a relatively See also:short slope to the plateau (4000-5500 ft.) of north-western Mongolia . East of 940 the range is continued by a See also:double See also:series of mountain chains, all of which exhibit less sharply marked orographical features and are at considerably See also:lower elevations . The southern See also:chain bears the names of Karaadzirga and Burkhan-ola, and terminates in about 990; but the northern range, the principal names of which are Artsi-bogdo and Saikhat, extends probably most of the way to the great north-See also:ward See also:bend of the Hwang-ho or Yellow River See also:round the See also:desert of Ordos . Whereas the western Ek-tagh Altai rises above the snow-line and is destitute of See also:timber, the eastern double ranges barely See also:touch the snow-line and are clothed with thick forests up to an See also:altitude of 6250 ft . The slopes of the constituent chains of the See also:system are inhabited principally by See also:nomad Kirghiz . The north-western and northern slopes of the Sailughem mountains are extremely steep and very difficult of See also:access . On this See also:side lies the culminating See also:summit of the range, the double headed Byelukha (the Mont See also:Blanc of the Altai), whose summitsreach 14,890 and 14,560 ft. respectively,' and give - origin to several glaciers (30 sq. m. in aggregate area) . Here also are the Kuitun (12,000 ft.) and several other lofty peaks . Numerous spurs, striking in all directions from the Sailughem mountains, fill up the space between that range and the lowlands of See also:Tomsk, but their mutual relations are far from being well known . Such are the Chuya See also:Alps, having an See also:average altitude of 9000 ft., with summits from 11,500 to 12,000 ft., and at least ten glaciers on their northern slope; the Katun Alps, which have a mean elevation of about 10,000 ft. and are mostly snow-clad; the Kholzun range; the Korgon (6300 to 7600 ft.), Talitsk and Selitsk ranges; the Tigeretsk Alps, and so on . Several secondary plateaus of lower altitude are also distinguished by geographers, The Katun valley begins as a See also:wild See also:gorge on the south-west slope of Byelukha; then, after a big bend, the river (400 M. long) pierces the Katun Alps, and enters a wider valley, lying at an altitude of from 2000 to 3500 ft., which it follows until it emerges from the Altai See also:highlands to join the Biya in a most picturesque region . The Katun and the Biya together See also: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 See also:

lake (altitude, 118o ft.), which is surrounded by fantastic See also:granite domes and towers . Farther west the valleys of the Uba, the Ulba and the Bukhtarma open south-westwards towards the Irtysh . The lower See also: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 See also:foot of the Ivanovsk See also:peak (6770 ft.), clothed with beautiful alpine meadows . The valley of the Bukhtarma, which has a length of 200 m., also has its origin at the foot of the Byelukha and the Kuitun peaks, and as it falls some 5000 ft. in less than 200 m., from an alpine plateau at an elevation of 6200 ft. to the Bukhtarma fortress (1130 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 comes down from the Byelukha . On the northern side of the range which separates the upper Bukhtarma from the upper Katun is the Katun See also:glacier, which after two See also:ice-falls widens out to 700-900 yards . From a grotto in this glacier bursts tumultuously the Katun river . The See also:middle and lower parts of the Bukhtarma valley have been colonized since the 18th See also:century by runaway See also:Russian peasants—See also:serfs and nonconformists (Raskolniks)—who created there a See also:free See also:republic on See also:Chinese territory; and after this part of the valley was annexed to See also:Russia in 1869, it was rapidly colonized . The high valleys farther north, on the same western See also:face of the Sailughem range, are but little known, their only visitors being Kirghiz shepherds . Those of Bashkaus, Chulyshman, and Chulcha, all three leading to the beautiful alpine lake of Teletskoye (length, 48 m.; maximum width, 3 m.; altitude, 1700 ft.; area, 87 sq. m.; maximum See also:depth, 1020 ft.; mean depth, 66o ft.), are only inhabited by nomad Telenghites or Teleuts .

The shores of the lake—reminding a visitor somewhat of the Swiss lake of See also:

Lucerne—rise almost sheer to over 6000 ft. and are too wild to accommodate a numerous See also:population . From this lake issues the Biya, which joins the Katun at Biysk, and then meanders through the beautiful prairies of the north-west of the Altai . Farther north the Altai highlands are continued in the See also:Kuznetsk See also:district, which has a slightly different See also:geological aspect, but still belongs to the Altai system . But the Abakan river, which rises on the western See also:shoulder of the Sayan mountains, belongs to the system of the See also:Yenisei . The Kuznetsk See also:Ala-tau range, on the See also:left See also:bank of the Abakan, runs north-east into the See also:government of See also:Yeniseisk, while a complexus of imperfectly mapped mountains (Chukchut, Salair, Abakan) fills up the See also:country northwards towards the Siberian railway and westwards towards the Ob . The Tom and its numerous tributaries rise on the northern slopes of the Kuznetsk Ala-tau, and their fertile valleys are occupied by. a ' Mr S . See also:Turner estimates the culminating peak of Mt . Byelukha at 14,800 ft., but to Willer's Peak, a little to the N . W. of Byelukha, he assigns an altitude of 17,800 ft .

Geology.—Geologically the Altai mountains consist of two distinct elements which differ considerably from each other in See also:composition and structure . The Russian Altai is composed mainly of See also:mica and See also:chlorite See also:schists and slates, together with beds of See also:limestone, and in the higher horizons Devonian and Carboniferous fossils occur in many places . There is no axial See also:zone of See also:gneiss, but intrusions of granite and other plutonic rocks occur, and the famous ore deposits are found chiefly near the contact of these intrusions with the schists . The strata are thrown into folds which run in the direction of the mountain ridges, forming a See also:curve with the convexity facing the south-east . The Mongolian or Great Altai, on the other See also:hand, consists mainly of gneiss and Archaean rocks . The strike of the rocks is See also:independent of the direction of the chain, and the chain is bounded by faults . It is, in fact, a See also:horst and not a zone of folding . See also:Flora.—The flora of the Altai, explored chiefly by Karl F. von Ledebour (1785-1851), is See also:rich and very beautiful . Up to a level of moo ft. on the northern and z000 ft. on the southern slopes, plant See also:life belongs to the See also:European flora, which extends into Siberia as far as the Yenisei . The See also:steppe flora penetrates into the mountains, ascending some 1100-1200 ft., and in sheltered valleys even up to 55oo ft., when it of course comes into contact with the purely alpine flora . See also:Tree vegetation, which reaches up as high as 65oo and 815o ft., the latter limit on the north and west, consists of magnificent forests of See also:birch, See also:poplar, See also:aspen, and Coniferae, such as Pinus cembra, Abies sibirica, Larix sibirica, Picea obovata, and so on, though the See also:fir is not found above 2500 ft., while the meadows are abundantly clothed with brightly-coloured, typical assortments of herbaceous See also:plants . The alpine meadows, which have many See also:species in See also:common with the' European Alps, have also a number of their own See also:peculiar Altaian species .

Mineral See also:wealth.—The Altai proper is rich in See also:silver, See also:copper, See also:lead and See also:zinc ores, while in the Kuznetsk Ala-tau, See also:gold, See also:iron and See also:coal are the chief mineral resources . The Kuznetsk Ala-tau mines are only now beginning to be explored, while the copper, and perhaps also the silver, ores of the Altai proper were worked by the mysterious prehistoric See also:race of the Chudes at a See also:time when the use of iron was not yet known . Russians began to mine in 1727 at Kolyvan, and in 1739 at See also:Barnaul . Most of the Altai region, covering an area of some 170,000 sq. m. and including the Kuznetsk district, has since 1746 formed a domain of the imperial See also:family under the name of the Altai See also:Mining District . The ores of the Altai proper nearly always appear in irregular See also:veins, containing silver, lead, copper and gold—sometimes all together,—and they are, or were, worked chiefly by Zmeinogorsk (or Zmeiev), Zyryanovsk, Ust-Kamenogorsk and Riddersk (abandoned in 1861) . They offer, however, great difficulties, especially on See also:account of their continually varying productivity and temperature of See also:fusion . The beautiful varieties of See also:porphyrySee also:green, red, striped—which are obtained, often in big monoliths, near Kolyvan, are cut at the imperial See also:stone-cutting factory into vases and other ornaments, See also:familiar in the See also:art galleries and palaces of See also:Europe . Aquamarines of mediocre quality but enormous See also:size (up to 3 in. in See also:diameter) are found in the Korgon mine . The northern, or Salair, mining region is rich in silver ores, and the mine of this, name used formerly to yield up to 93,300 oz. of silver in the See also:year . But the chief wealth of the northern Altai is in the Kuznetsk coal-basin, also containing iron-ores, which fills up a valley between the Kuznetsk Ala-tau and the Salair range for a length of about 270 m., with a width of about 65 m . The coal is considered equal to the best coal of See also:England and south Russia . The country is also covered with thick diluvial and alluvial deposits containing gold .

However, all the mining is now on the decline . Population.—The Russian population has rapidly increased since the fertile valleys belonging to the imperial family have been thrown open to See also:

settlement, and it has been estimated that in 1908 the population of the region (Biysk, Barnaul and Kuznetsk districts) reached about 800,000 . Their chief occupations are See also:agriculture (about 3,500,000 acres under culture), See also:cattle-breeding, See also:bee-keeping, mining, gathering of See also:cedar-nuts and See also:hunting . All this produce is exported partly to Tomsk and partly to Kobdo in Mongolia . The natives may represent a population of about 45,000 . They are Altaians in the west and Telenghites or Teleuts in the east, with a few Kalmucks and See also:Tatars . Although all are called Kalmucks by the Russians, they speak a See also:Turkish See also:language . Both the Telenghites and the Altaians are Shamanists in See also:religion, but many of the former are already quite Russified . The virgin forests of the Kuznetsk Ala-tau—the Chern, or See also:Black See also:Forest of the Russians—are peopled by Tatars, who live in very small settlements, sometimes of the Russian type, but` mostly in wooden yurts or huts of the Mongolian See also:fashion . They can hardly keep any cattle, and lead the See also:precarious life of forest-dwellers, living upon various wild roots when there is no See also:grain in the See also:spring . Hunting and fishing are resorted to, and the skins and furs are tanned . Towns.—The See also:capital of the Altai region is Barnaul, the centre of the mining See also:administration and an animated commercial See also:town; Biysk is the commercial centre; Kuznetsk, Ust-Kamenogorsk, and the mining towns of Kolyvan, Zmeinogorsk, Riddersk and Salairsk are the next largest places .
