The Sayan Mountains (Russian: Саяны Sajany; Mongolian: Соёны нуруу, Soyonï nurû; Kogmen Mountains during the period of the Göktürks) are a mountain range in southern Siberia, Russia (the Tyva Republic specifically) and northern Mongolia. In the past, it served as the border between Mongolia and Russia.
The Sayan Mountains' towering peaks and cool lakes southwest of Tuva give rise to the tributaries that merge to become one of Siberia's major rivers, the Yenisei River, which flows north over 2000 miles to the Arctic Ocean. This is a protected and isolated area, having been kept closed by the Soviet Union since 1944.

|Elevation||3,492 m (11,457 ft)|
The Eastern Sayan extends 1,000 km (621 mi) from the Yenisei River at 92° E to the southwest end of Lake Baikal at 106° E. The Western Sayan forms the eastern continuation of the Altay Mountains, stretching for 500 km (311 mi) from 89° E to the middle of the Eastern Sayan at 96° E.
While the general elevation is 2000 to 2,700 m (8,858 ft), granites and metamorphic slates reach altitudes of over 3,000 m (9,843 ft), with the highest being Mönkh Saridag at 3,492 m (11,457 ft). The principal mountain passes lie 1800 to 2,300 m (7,546 ft) above the sea, for example Muztagh pass at 2,280 m (7,480 ft), Mongol pass at 1,980 m (6,496 ft), Tenghyz pass at 2,280 m (7,480 ft) and Obo-sarym pass at 1,860 m (6,102 ft).
At 92°E the system (the Western Sayan) is pierced by the Ulug-Khem (Russian: Улуг-Хем) or Upper Yenisei River, and at 106°, at its eastern extremity, it terminates above the depression of the Selenga-Orkhon Valley. From the Mongolian plateau the ascent is on the whole gentle, but from the plains of Siberia it is much steeper, despite the fact that the range is masked by a broad belt of subsidiary ranges of an Alpine character, e.g. the Usinsk, Oya, Tunka and Kitoi ranges.
Between the breach of the Yenisei and Lake Khövsgöl at 100° 30' E. the system bears also the name of Yerghik-taiga. The flora is on the whole poor, although the higher regions carry good forests of larch, pine, juniper, birch, and alder, with rhododendrons and species of Berberis and Ribes. Lichens and mosses clothe many of the boulders that are scattered over the upper slopes.
In this area that currently shows only small cirque glaciers, at glacial times glaciers have flowed down from the 3492 m high Munku Sardyk massif situated west of Lake Baikal and from the 12.100 km² extended completely glaciated granite-gneiss plateau (2300 m asl) of the East-Sayan mountains as well as the east-connected 2600 – 3110 m-high summits in the Tunkinskaya Dolina valley, joining to a c. 30 km-wide parent glacier. Its glacier tongue that flowed down to the east, to Lake Baikal, came to an end at 500 m asl (51°48’28.98"N/103°0’29.86"E). The Khamar Daban mountains were covered by a large-scale ice cap filling up the valley relief. From its valley heads, e.g. the upper Slujanka valley (51°32’N/103°37’E), but also through parallel valleys like the Snirsdaja valley, outlet glaciers flowed to the north to Lake Baikal. The Snirsdaja-valley-outlet glacier has calved, among other outlet glaciers, at c. 400 m asl into Lake Baikal (51°27’N/104°51’E). The glacial (Würm ice age = Last Glacial Period = MIS 2) glacier snowline (ELA) as altitude limit between glacier feeding area and ablation zone has run in these mountains between 1450 and 1250 m asl. This corresponds to a snowline depression of 1500 m against the current height of the snowline. Under the condition of a comparable precipitation ratio there might result from this a glacial depression of the average annual temperature of 7.5 to 9 °C for the Last Ice Age against today.
According to Sev’yan I. Vainshtein Sayan reindeer herding, as historically practiced by the Evenks, is "the oldest form of reindeer herding and is associated with the earliest domestication of the reindeer by the Samoyedic taiga population of the Sayan Mountains at the turn of the first millenium A.D. (...) The Sayan region was apparently the origin of the economic and cultural complex of reindeer hunters-herdsmen that we now see among the various Evenki groups and the peoples of the Sayan area.
The ancestors of modern Evenki groups inhabited areas adjacent to the Sayan Mountains, and it is highly likely that they took part in the process of reindeer domestication along with the Samoyedic population." The local indigenous groups that have retained their traditional lifestyle nowadays live almost exclusively in the area of the Eastern Sayan mountains. However, the local reindeer herding communities were greatly affected by russification and sovietization, with many Evenks losing their traditional lifestyle and groups like the Mator and Kamas peoples being assimilated altogether.
Acossus terebra is a species of moth of the family Cossidae. It is found in Eurasia, including Israel, Turkey, northern Spain, central and southern Europe, southern Sweden, Finland, the Baltic region, Ukraine, the central part of European Russia, the Caucasus, southern Siberia (including the Altai and Sayan Mountains) to southern Yakutia, the southern part of the Russian Far East, Korea, Heilongjiang, Jilin and inner Mongolia.The wingspan is 55–64 mm.

The Baikal Mountains or Baikal Range (Russian: Байкальский хребет, Bajkaljskij hrebet; Buryat: Байгалай дабаан, Baigalai dabaan) rise steeply over the northwestern shore of Lake Baikal in southern Siberia, Russia. The Central Siberian Plateau is bounded on the south by the Eastern Sayan Mountains and the Baikal Mountains.
The Baikal Mountains are the origin of the Lena River. The mountains around Lake Baikal are densely wooded with Grey Alder, Eurasian Aspen, Downy Birch, Siberian Larch, Siberian Fir, Scots Pine, and Siberian Spruce.Its highest peak is the Chersky Mountain (2,572 m) named after the Polish explorer, Jan Czerski.Kamassian language
Kamassian is an extinct Samoyedic language, included by convention in the Southern group together with Mator and Selkup (although this does not constitute an actual subfamily). It had two dialects: Kamassian (also known as Kamas) and Koibal. The last native speaker of the Kamassian dialect, Klavdiya Plotnikova, died in 1989. Kamassian was spoken in Russia, north of the Sayan Mountains, by Kamasins.
The term Koibal is also used as the ethnonym for the Kamas people who shifted to the Turkic Khakas language; the modern Koibal people are mixed Samoyed–Khakas–Yeniseian.Kan River
The Kan (Russian Кан) river is a 629-kilometre (391 mi) long tributary of the Yenisei River in Siberia, Russia. It drains a basin of 36,900 square kilometres (14,200 sq mi).
The headwaters of the river rise in the Sayan Mountains and flow from there in a northerly direction through Kansk and then in a westerly direction through Zelenogorsk, entering Yenisei at Ust-Kan, 69 kilometres (43 mi) north-east of Krasnoyarsk).Kitoy range
The Kitoy Range (Russian: Китойские гольцы) is a mountain range in Siberia, Russia, part of the Eastern Sayan Mountains.
Length: 180 km
Highest summit: 3215 m
Rivers: Kitoy River and other tributaries of the Angara River.List of butterflies of Russia
This is a list of butterflies of Russia. About 540 species are known from Russia. The butterflies (mostly diurnal) and moths (mostly nocturnal) together make up the taxonomic order Lepidoptera.
The history of lepidopterology in Russia is connected with the organization of the first Russian museum The Kunstkamera established by Peter the Great in 1714. In 1717, he purchased the collection of Albert Seba, a merchant from Amsterdam, for the new museum. In 1832 the Zoological Museum of the Imperial Academy of Sciences was separated as a distinct institution which in 1931 became the Zoological Institute of the USSR Academy of Sciences (since 1991 — Russian Academy of Sciences).
In 1859, the then director of the Zoological Museum, Johann Friedrich von Brandt was one of the founders of the Russian Entomological Society in 1859 and in St. Petersburg . Other founders were Karl Ernst von Baer, Ya. A. Kushakevich, Colonel Alexander Karlovich Manderstern, Alexander von Middendorff and Colonel of General Staff Victor Ivanovitsch Motschulsky. Another society founder was Ferdinand Morawitz. Eduard Brandt and Ferdinand Morawitz. Also important was the Moscow Society of Naturalists and increasingly the Russian Academy of Sciences and The Academy of Sciences of the USSR. From the mid-nineteenth century the main zoogeographic focus was on the Caucasus, Siberia and the Russian Far East. At the end of the nineteenth century the German entomologist Otto Staudinger financed collectors in the Far East of Russia. In the early twentieth century the results of all these endeavours were summarised in Die Gross-Schmetterlinge der Erde edited by Adalbert Seitz.
From 1925 lepidopterology was organised by The Academy of Sciences of the USSR and lists titled USSR or SSR. In 1991 The Academy of Sciences of the USSR became once again the Russian Academy of Sciences.
Notable Russian lepidopterists include Peter Simon Pallas, Johann Friedrich von Eschscholtz, Édouard Ménétries, Johann von Böber, Hugo Theodor Christoph, Alexander Yakhontov, Alexander von Nordmann, Vasily Evgrafovich Yakovlev, Victor Motschulsky, Sergei Alphéraky, Otto Vasilievich Bremer, Grigory Grumm-Grzhimaylo, Alexei Fedchenko, Nicholas Mikhailovich, Nikolay Grigoryevich Erschoff, Nikolai Yakovlevich Kuznetsov, Grigory Bey-Bienko and Yuri Korshunov.
Butterflies of RussiaList of lakes of Mongolia
The lakes in Mongolia are distributed unevenly across the country. Many, including some of the largest, can be found in the Great Lakes Depression between the Altai, Khangai and Tannu-Ola mountain ranges in the west. A second group can be found in mountain valleys throughout the country. Lake Khövsgöl in a rift valley south of the Russian Sayan Mountains has the largest volume because of its great depth. The remaining lakes found in the steppe areas and in the Gobi desert are usually smaller and shallow.
The total area of the lakes is 16,003 km². The 83.7% of the total lakes number are the small lakes with surface area less than 0.1 km² (5.6% of the total area). There are 3,060 lakes with surface area 0.1 km² and more.Mator language
Mator or Motor was a Uralic language belonging to the group of Samoyedic languages, extinct since the 1840s. It was spoken in the northern region of the Sayan Mountains in Siberia, close to the Mongolian north border. The speakers of Mator lived in a wide area from the eastern parts of the Minusinsk District (okrug) along the Yenisei River to the region of Lake Baikal. Three dialects of Mator were recorded: Mator proper as well as Taygi and Karagas (occasionally portrayed as separate languages, but their differences are few).
Today the term "Mator people" is simply an alternate name of the Koibal, one of the five territorial sub-division groups of the Khakas. (Note that the name "Koibal" likewise derives from the related Samoyedic Koibal language.)
Mator has been frequently grouped together with Selkup and Kamassian as "South Samoyedic". This is however a grouping by geographical area, and not considered to constitute an actual sub-branch of the Samoyedic languages.Mönkh Saridag

Sayano-Shushenski Nature Reserve (Russian: Саяно-Шушенский заповедник) (also Sayano-Shushensky) is a Russian 'zapovednik' (strict ecological reserve) reserve in a remote area of the West Sayan Mountains of south Siberia. It is on the southern bank of the Yenisei River along the Sayano-Shushenskoye reservoir. The reserve thus protects a large section of the wooded, mountainous territory above the reservoir created by the Sayano-Shushenskaya Dam, the largest power plant in Russia. Both the reserve and the dam were established 1976, and a major purpose of the reserve besides conservation is the study of the ecological effects of a large reservoir on the local ecology. The reserve covers an area of 390,368 ha (1,507.22 sq mi). It is situated in the Shushensky District of Krasnoyarsk Krai.Shushensky Bor National Park
