The Verkhoyansk Range is tectonic. Mountain system Verkhoyansk Range

The southeastern extension of the Verkhoyansk Range is called the Sette-Daban Range, which is distinguished by a different relief and geological structure. The northern end is formed by the Tuora-Sis and Kharaulakhsky ridges with a height of less than 1000-1250 m. The meridional part of the mountain country Verkhoyansk ridge - the Orulgan ridge - is formed by the highest ridges - 2100-2300 m (the highest point is 2389 m). A narrow and long Kular ridge with a height of up to 1300 m branches off from the Orulgan ridge in the East. In the latitudinal section of the Verkhoyansk ridge, the heights of mountain peaks exceed 2000 m.

The pass saddles in most of the mountainous country lie at altitudes of 1300-1500 m. The river valleys of the western and southern slopes are deep, with traces of glacial processing, and amphitheaters of terminal moraines are observed at their exits to the plain. The crests of the ridges often have sharp alpine landforms. On the tops of the ridges and massifs there are significant areas of the ancient leveled relief, better preserved in the Yana basin. In tectonic terms, the Verkhoyansk Range is an anticlinorium composed of siltstones, sandstones, shales, and less often limestones (Verkhoyansk complex). In some places, sedimentary rocks are intruded by diabase dikes, as well as granite intrusions, which are associated with deposits of gold and tin.

The climate is cold, sharply continental. During a long winter, temperature inversions are characteristic, especially sharp in the foothills, in depressions and large river valleys. The average January temperature is -36, -38°С. Summer is short, relatively warm in the South in the valleys (average temperature in July is 12-14°C). Almost an annual amount of precipitation falls in summer, the largest amount - up to 600 mm per year - on the western slopes of Orulgan. Perennial frozen rocks are ubiquitous, which is the reason for the formation of icing. On the tops of the highest ridges there is a cold arctic desert. Lower down the slopes, on gravel and loamy soils, miserable mountain-tundra vegetation appears, giving way even lower to thickets of elfin cedar, creeping birch, shrubby alder and polar willow. In the South, the lower parts of the slopes of the mountains up to a height of 800-1200 m are covered with sparse larch forests. There are numerous steppe areas on the slopes of the southern exposure. On the alluvial podzolized soils of the bottoms of the valleys of large rivers, along with larch forests, there are forests formed by pine and birch, occasionally spruce, fragrant poplar groves, and thickets of shrubs.

The Verkhoyansk Range - in the Yakutsk region, constitutes a spur of the Stanovoy Range, from which, having separated at 64 ° 30 "N. Lat., It initially goes to the west, and then, turning from the mouth of the Aldan to the NNW, gradually lowering, merges with the northern tundra. Its own This range received its name from the Yana River, which originates on its northern slope.The V. Ridge and its spurs form the watershed of the Aldan, Lena, Indigirka, and Kolyma rivers with their tributaries. ; the pass itself through it along the Verkhoyansk tract is defined as 1220 m (4700 ft.), lined with rocks 210 m (700 ft.) high. The ascent to the pass from the south is difficult due to its steepness, ledges of large stones on the path, which in some places is no more than a yard wide and winding over an abyss, at the top of the pass there is a platform of only 20 square arshins, followed by a descent to the north, less steep than the ascent to the ridge from the south. about snow, but in the upper reaches of the rivers originating in it, taryns are often found, that is, very significant layers of ice in river channels that do not disappear during the summer; these taryns, stretching in length up to 2 - 3 versts, consist of numerous layers of transparent ice, among which the river makes its way in many channels. Several spurs separate from the Verkhoyansky Range, of which the main one, Tas-Khayakhtakh, goes to S.V. and serves as a watershed between Yana and Indigirka; the other, Tas-Tabalakh, heads to the NNE between pp. Indigirka and Alazeya, its final branch is called the Alazeya Mountains, serving as the watershed of the Kolyma and Alazeya rivers. From the mouth of the Aldan River, the Verkhoyansk Range, extending to the CVD, forms the watershed of the Yana and Lena; moreover, its northern spurs partly reach the sea coast, bearing the name Oruglan. The branch of this ridge, lying to the east from the village of Bulun, is known as the Kharaulakh Mountains; going down to the Lena delta, it is lost in the tundra. All these mountain spurs, deposited and below the East Ridge and near the Arctic Sea, end in insignificant hills. Verkhoyansk The ridge represents the boundary of the distribution of certain tree species that are no longer found on its northern slopes, such as pines, spruces, mountain ash, and some others.

The geognostic structure of the ridge is monotonous: the southwestern slopes consist of sandstones and shaly clay with layers of coal and plant remains; the northeastern slope is dominated by sandstones and shales with coal-bearing deposits. Between the fossils found in the Verkhoyansk Range, the shells of Monotis Salinaria and others turned out to be identical to the Triassic of Svalbard and belong to the area of the Mesozoic deposit, which has a rather extensive distribution in northern Siberia. Crystalline rocks are found only in the watershed of the East Ridge and consist of granites and feldspar porphyries that uplift the ridge. From the mineral wealth of the V. Ridge, the presence of silver-lead ores along the Echiya River, which flows into the Dulgalakh, is known. The first news about finding silver ore along the river. Yundybalu dates back to 1748. Here, from 1765 - 1775, development was carried out at different times, and although these ores turned out to be rich in silver content, but due to the remoteness and low population of the area and the lack of forest, their development was extremely difficult and therefore abandoned. The Alazeya spurs of the Verkhoyansk Range abound in native iron.

Verkhoyansk Range, a mountainous country in the North-Vorstok of Yakutia. It is formed by numerous mountain ranges, massifs and depressions separating them. The watershed of the Lena with Yana and Omoloy passes along the Verkhoyansk Range. It stretches for 1200 km from the Lena delta to the Tompo River (the right tributary of the Aldan), forming a convex arc in the South-West with a width of 100 to 250 km. The southeastern extension of the Verkhoyansk Range is called the Sette-Daban Range, which is distinguished by a different relief and geological structure.

The Alazeya spurs of the Verkhoyansk Range abound in native iron.

However, it does not accurately reflect its geographical location: on the slopes of the ridge is not the upper reaches of the Yana River itself, but the rivers Dulgalakh and Sartang that form it.
The Verkhoyansk Range stretches in an arc along the right bank of the lower reaches of the river, for 1200 km from its delta in the northwest to the Tompo River - a tributary of the Aldan River - in the southeast. It consists of dozens of ridges with mid-mountain (Orulgan ridge) and low-mountain (Kular and Kharaulakh ridges) relief. The crest of the ridge is crossed by deep gorges of the rivers of the Lena basin. The heights of the mountain peaks of the Verkhoyansk Range reach more than 2000 m.
In historical and geological terms, the Verkhoyansk Range belongs to the Verkhoyansk-Chukotka folded region, the formation of which took place in the Mesozoic era - 200-150 million years ago.
The rocks that make up the Verkhoyansk Range are mainly sandstone, shales, and limestone. In the west of the range, the folds formed by them form parallel mountain ranges. Outcrops of hard rocks - primarily granite - are observed in the center and east.
Traces of mountain-valley glaciation are visible everywhere, there are small areas of glaciers, and large ice floes have formed in the valleys. Permafrost is present everywhere.
The nature of the Verkhoyansk Range has a typical high-altitude character: larch taiga at an altitude of up to 800-1200 m, higher - thickets of shrubby alder and elfin cedar, the peaks are occupied by mountain tundra and char.
The climate here is very cold, long winters are characterized by temperature inversions in depressions and large river valleys, and summers in Verkhoyansk are short.
The Verkhoyansk Range is a territory of a very cold climate; during a long winter, temperature inversions occur when cold air masses stagnate in the foothills, in depressions and large river valleys, and the temperature rises with height. This area is the realm of permafrost rocks, which is the reason for the formation of icing. The peaks of the Verkhoyansk Range are a zone of cold arctic desert.
The Verkhoyansk Range is a place of occurrence of ores of gold and silver. The first information about the presence of precious metal deposits here was collected by an expedition sent to these parts in 1748 at the behest of the Russian Empress Elizabeth I Petrovna (1709-1761). Due to the remoteness of the deposits from roads and river rapids, ore mining began only during the reign of Catherine II the Great (1762-1796), who released significant funds from the treasury for the exploration and development of Verkhoyansk. From 1765 to 1775 here the development of silver deposits was carried out, which turned out to be very rich. However, funds for their development and export had to be spent almost more than the cost of the mined ore. Since ancient times, native iron deposits have been known in the Alazeya spurs of the Verkhoyansk Range, but their development was also complicated by their remoteness from the roads.
Already in Soviet times, when the Soviet geologist and future academician Sergey Obruchev (1891-1965) was engaged in the study of North-Eastern Siberia, tin was found here.
The population in the region of the Verkhoyansk Range - mostly Yakuts - is not numerous and lives in small villages, is engaged in hunting and fishing. There are also reindeer farms on the eastern slope of the ridge, while the southern slope is considered sparsely inhabited.
In one of the depressions of the Verkhoyansk Range is the village of Tomtor - one of the contenders for the title of "Pole of Cold" in the Northern Hemisphere of the Earth: the winter temperature is up to -50°C. In the village of Tomtor there is a cave of Chyskhaan - the Yakut Father Frost. In addition, the Pole of Cold festival is held annually in Tomtor.

Curious facts

■ Loaches (common in Verkhoyansk) in Siberia are called mountain peaks or mountain ranges that rise above the upper border of the forest. The tops of the loaches are flat, covered with scatterings of small stones and tundra vegetation: mosses, lichens, dwarf pine, dwarf birch and juniper.
■ The Verkhoyansk Range serves as a climatic barrier between the inaccessible, cold Verkhoyansk Territory and the rest of Yakutia.
■ The Verkhoyansk Range, together with the spurs belonging to it, is several times larger than the system of ridges of the Greater Caucasus.

■ One of the most common plants in the highland meadows of Verkhoyansk is partridge grass, or dryad, named after a nymph from ancient Greek mythology.

There is a harsh and beautiful mountainous country, stretching for 1200 km along the Lena - the Verkhoyansk Range, which amazes with its natural beauties. It is located on the border of two large lithospheric plates, the North American and, respectively, the Eurasian. It consists of dozens of ridges of different heights. The Verkhoyansk ridge, with heights of individual mountain ranges above 2,000 meters, is a watershed for the Lena and Aldan rivers with the Yana and Indigirka.

Tectonics and geology

In characterizing the tectonics of the territory, it should be noted that it is the boundary between two large structures, the Eurasian and North American lithospheric plates. The main ranges joined the Precambrian Siberian platform in the Mesozoic Triassic (160-70 Ma). At that time, active tectonic processes formed the entire north-east of the country.

The ridge is a large zone of tectonic uplifts - an extensive anticlinorium. It is composed mainly of ancient sandstones, ancient siltstones, shaly clays, shales with coal seams and limestones.

In places, the sediment layers are intruded by large dikes of ancient diabases and thick granite intrusions. These structures are associated with large deposits of tin and native gold. Strong volcanic rocks, coarse-grained granites and feldspar porphyries, are found in the watershed part of the ridge.

Relief

The relief of the territory is quite complex, it consists of a whole group of ridges of different heights and vast depressions separating them. The main part here is the Orulgan ridge with heights of 2100-2300 m. The highest point is also located here - a nameless mountain with a mark of 2409 m.

Dissected by river valleys, Orulgan is composed of ancient limestones, sandstones and shales. Up to a height of 1200 m, sparse larch forests grow on all the slopes of Orulgan, and rocky tundra stretches higher up the slopes. From Orulgan to the east there is a narrow and long Kular mountain range up to 1300 m high.

In the north there is Tuora-Sis and the more elevated Kharaulakhsky, from 1000 to 1250 m. In the southeast it continues with the Sette-Daban ridge, which differs from the main ridges in its relief pattern and complex geological structure. In the widest part of the Verkhoyansky ridge, heights reach 2000 m. Mountain passes here are at an altitude of 1.3-1.5 thousand m.

The valleys of mountain rivers here are deep, canyon-like with clear traces of glacier processing and amphitheatres of ancient glacial moraines. The ridges of the local ridges have clear sharp alpine outlines. On the peaks and intermountain depressions, especially in the Yana valley, glacier-leveled areas are found everywhere.

Climate

The climatic conditions of the region of the Verkhoyansk Range are rather cold, harsh, sharply continental. Here in Verkhoyansk winter is extremely severe, here is one of the most extremely cold places on the planet and in the northern hemisphere. The average temperature in January is -45.5°C, the absolute minimum can drop to -67.8°C. In winter, with a general cooling of the air, temperature inversions are observed.

Summer in Verkhoyansk is short, cool, and frosts can be observed even in the middle of the summer season. The average July temperature is +16.5°C, the absolute maximum is +37.3°C. There is little precipitation in summer, as well as in all seasons. In the warm season, up to 600 mm falls on the western slopes of the Orulgan ridge. Permafrost rocks are ubiquitous here, which leads to the formation of abundant icing.

Hydrology

The main river flowing in the region of the Verkhoyansk Range is the lower reaches of the Lena. The river here has already gained strength, is vast and full of water. Its width here reaches 10 km, where many islands form with a calm current, the width can reach 20-30 km. In the lower reaches, the depth of the river can reach 20 m.

The rivers flowing from the spurs of the Verkhoyansk ridge to the Lena are rather short, since the valley narrows noticeably from the side of the watershed ridge. The Kharaulakh Range further narrows the Lena Valley from the east, and about 150 km from the Laptev Sea, which receives the waters of the river, a vast tree-like river delta begins, divided into many channels.

The rivers flowing from the Verkhoyansky ridge to the east, Dulgalakh and Sartang, form the Yana at the confluence. These are quite large rivers, the length of Sartang is 620 km, Dulgalakh is 507 km. Sartang begins its course in Lake Siskyuele on one of the northern slopes, flows along the Yan Plateau and merges with Dulgalakh at an altitude of 132 m. Dulgalakh also begins on one of the northern slopes and flows in the very upper reaches through a flowing lake called Syuryun-Kyuyol, merges with Sartang.

Sartang at 175 km from the mouth is navigable, Dulgalakh at 200 km is used for timber rafting. Rivers feed on sediments and tributaries flowing into them. High water on the rivers of the Verkhoyansk Range is observed from June to September. The lowest runoff is observed from February to April. The rivers freeze in October, often freeze from November to May, and break up by the end of May.

Numerous sources of Omoloy are located in one of the spurs - the Sietindensky ridge. Omoloy flows in a northerly direction near the mountain range of the Kular ridge. Below Omoloy it flows into the estuary formed by him of the Buor-Khaya Bay, which is cold and ice-covered for most of the year, the Laptev Sea. The Omoloi watercourse is fed by precipitation, it is covered with ice in October, the ice melts by June. The northern river is extremely rich in various fish; in its delta, there is a wonderful fishery for delicacy omul. Omoloi was the name of one of the leaders of the Yukaghir family, who have long lived on its banks.

Nature

Forests on the slopes of the ridge occupy an area of 63.5 thousand square meters. km., which is up to 24% of its area. There are forests up to a height of 1100-1300 m above sea level. y. m. The basis of the forests of the mountainous country is larch, a hardy tree that has adapted well to the harsh northern conditions. Larch is undemanding to heat, well tolerates extremely cold local temperatures. The plant is tolerant of dry air and nutrient-poor soils.

An important role in the formation of the forests of the Verkhoyansk Range is played by tree-like and stunted birches. There are massifs of aspen forests and elfin cedar here. There are practically no steppes here, but areas of steppe vegetation are found in forests, in flat-topped areas, among loaches, shrubs and mountain tundra.

The shrub belt separates the forest and the mountain tundra on the slopes. The area of shrubs here occupies 41.5 thousand square meters. km., or up to 15% of the territory. The dwarf pine, which is often called the dwarf pine, is widely represented in it. This is a very openwork-looking low creeping woody plant with branches spread wide across the ground.

Among the undergrowth in coniferous forests, on gravel slopes of river banks, in swamps and burnt areas, on rocky slopes and placers, shrub alder is often found. It usually grows as a shrub or a low tree up to 6 m. Thickets of alder noticeably decorate the slopes of the mountains and stone placers with lush greenery.

In swampy areas, in the undergrowth of mixed and deciduous-spruce forests, among shrub massifs, along the banks of reservoirs, birch is often found here. It grows most often as a tall shrub no more than 2 m tall with smooth dark-skinned shoots. Around, in addition to chars and placers, there is a powerful development of an almost continuous cover of mosses and lichens.

Attractions

In the lower reaches of the Lena there is a unique natural geological object, the so-called Chekurov cheeks. Here Lena, having already gained natural strength and power, cuts through the rocky volcanic spurs of the ridge. The rocks stretched near the river flow for more than 3 km. This is, in fact, the last rocky barrier that stood in the way of the river before flowing into the sea.

Lena flows here in a deep canyon with rocky banks up to four hundred meters high, its stream is clamped by strong rocks up to a width of 2 km. Almost sheer rock walls rise above its water. Compressed by rocks, the river boils and foams, Chekurovsky cheeks are a serious obstacle for river vessels.

The passage of ships along the Chekurovsky cheeks is very dangerous, the sailors call it the common epithet "cemetery of ships." In the summer of 1957, a large barge hit hard on the monoliths of the Chekurosky cheeks and quickly sank, it was driven along the fairway by the steamer Engels. The barge was loaded with souvenirs intended for the celebration of the 325th anniversary of the entry of the Republic of Yakutia into Russia.

The first of the right-bank cheeks stretches along the coast for up to 1 km and looks like a monolithic horseshoe-shaped rock. The second cheek on the left bank is perpendicular to the first. Between the first and, respectively, the third cheeks, along the fall named after the geologist Ponomarev, along the path you can go to the very top of the third of the cheeks.

Another very remarkable place in this harsh region is the remnant rock of Stolb Island, once torn off by Lena from the Tuora-Sis ridge. A high rock in the riverbed of the Lena, 104 m high, has long been a place of worship for local tribes to the spirits of their native nature. At its top, an ancient sanctuary with traces of fire rituals, a sixth in the middle and ribbons tied to it has been preserved to this day.

A unique corner of this, visible from space, is the Lena Delta. She simply amazes with her virgin beauty and abundance of life. Severe but magnificent ice shores, blown by all winds, have become a home for millions of nesting birds, wild ducks and geese, sea gulls and white-tailed eagles, golden eagles and gyrfalcons, cranes and Siberian Cranes, waders and loons.

And Sartang. The confluence of these rivers and the beginning of the Yana ("upper Yana") lies 250 km to AT. from the watershed of the Verkhoyansk Range and is located on the Yanek Plateau, which belongs to the Yansko-Oymyakon Highlands.
