The range lies just west of the boundary of the Eurasian and the North American tectonic plates . The mountains were formed by folding , and represent an anticline . The Verkhoyansk Range was covered by glaciers during

125-642: Is a river in the Russian Far East and is the easternmost river of the three, great rivers of Siberia , including the River Ob and the River Yenisey , which flow into the Arctic Ocean . The Lena river is 4,294 km (2,668 mi) long and has a capacious drainage basin of 2,490,000 km (960,000 sq mi); thus the Lena is the eleventh-longest river in the world and

150-507: Is commonly believed that the Lena derives its name from the original Even-Evenk name Elyu-Ene , which means "the Large River". According to folktales related a century later, in the years 1620–1623 a party of Russian fur hunters under the leadership of Demid Pyanda sailed up Nizhnyaya Tunguska , discovered the Lena, and either carried their boats there or built new ones. In 1623 Pyanda explored some 2,400 kilometres (1,500 mi) of

Lakes Nedzheli and Ulakhan-Kyuel are the largest in the basin of the Lena. The Kirenga flows north between the upper Lena River and Lake Baikal. The Vitim drains the area northeast of Lake Baikal. The Olyokma flows north. The Amga makes

225-756: The Central Siberian Plateau . At the end of the Lena River there is a large delta that extends 100 kilometres (62 mi) into the Laptev Sea and is about 400 km (250 mi) wide. The delta is frozen tundra for about seven months of the year, but in May the region is transformed into a lush wetland for a few months. Part of the area is protected as the Lena Delta Wildlife Reserve . The Lena delta divides into

250-772: The Chersky Range , reaching the Lena Plateau to the south and the Yudoma-Maya Highlands to the southeast. It forms a vast arc between the Lena and Aldan rivers to the west and the Yana River to the east. The Verkhoyansk Range has a higher southeastern prolongation than the Suntar-Khayata Range , which is occasionally considered as a separate range system. Thus the highest point of

275-685: The Last Glacial Period and the mountains in the northern section, such as the Orulgan Range , display a typical Alpine relief. There are coal , silver , lead , tin , and zinc deposits in the mountains. Rising from the shores of the Buor-Khaya Gulf in the north, it runs southwards spanning roughly 1000 km (600 mi.) across Yakutia , east of the Central Yakutian Lowland , and west of

300-739: The Lena-Angara Plateau , then is joined by three tributary rivers: (i) the Kirenga river, (ii) the Vitim river, and (iii) the Olyokma river. From Yakutsk , the Lena river enters the Central Yakutian Lowland and flows north until joined by the eastern tributary, the Aldan river , and the western tributary, the Vilyuy river . Afterwards, the Lena bends westwards and northwards, flowing between

325-562: The Lena delta and the islands of New Siberia on behalf of the Russian Imperial Academy of Sciences in 1885. In 1886 they investigated the New Siberian Islands and the Yana River and its tributaries. During one year and two days the expedition covered 25,000 kilometres (16,000 mi), of which 4,200 kilometres (2,600 mi) were up rivers, carrying out geodesic surveys en route. The Lena massacre

350-565: The Orulgan, the system of the range comprises a number of subranges, as well as a plateau, including the following: The Verkhoyansk mountain system separates the basins of the Lena River to the west and southwest and the Omoloy and Yana to the east and northeast. It is deeply cut by riverine intermontane basins . Many right tributaries of the Lena flow westwards, having their sources in

375-694: The course of an expedition sent by the government of the Soviet Union. After conducting the first topographic survey of the area, Bilibin established that the Skalisty and Sette-Daban mountain chains belong to the Verkhoyansk Mountain System. Bilibin and Bobin also explored for the first time the Yudoma-Maya Highlands , located to the southeast of the Ulakhan-Bom/Sette-Daban/Skalisty ranges. Besides

400-545: The longest river entirely within Russia . Geographically, permafrost is the type of soil that underlies most of the Lena river's catchment , twenty per cent (20%) of which is continuous. The Lena river originates at 1,640 meters (5,381 ft) of elevation in the Baikal Mountains , 7 kilometres (4 mi) west of Lake Baikal , south of the Central Siberian Plateau . The Lena river flows north-east and traverses

425-491: The most important being the Bykovsky channel, farthest east. The Lena is navigable over a length of 3540 kilometres. The annual navigation period, when ice is minimally present or absent, lasts about 70 days in the estuarine region and 125 days elsewhere. The area of the Lena river basin is calculated at 2,490,000 square kilometres (960,000 sq mi) and the mean annual discharge is 489 cubic kilometers per year. Gold

450-787: The mountains of the Kharaulakh Range to the east (part of the Verkhoyansk Range ) and the mountains of the Chekanovsky Ridge to the west. Travelling approximately due north, the Lena river widens into a great river delta that merges into the Laptev Sea , a marginal region of the Arctic Ocean, south-west of the New Siberian Islands . The Lena Delta is 30,000 square kilometres (12,000 sq mi) in area, being traversed by seven main branches,

475-564: The range in a restricted geographical sense is an unnamed 2,409-metre (7,904 ft)-high peak in the Orulgan Range . The Ulakhan-Bom , highest point 1,600 metres (5,200 ft), Sette-Daban , highest point 2,012 metres (6,601 ft), and Skalisty Range (Rocky Range), highest point 2,017 metres (6,617 ft), are located at the southern end and were also considered separate ranges in classical geographic works. The two ranges were surveyed in 1934 by geologist Yuri Bilibin (1901–1952) together with mining engineer Evgeny Bobin (1897–1941) in

500-605: The range in its southern part, flowing from its source in the Suntar Khayata. The valley of the Aldan is located to the south, where the river makes a wide bend. From the eastern slopes flow the rivers Dulgalakh and Sartang , which form river Yana further north, as well as its tributaries Bytantay , Nelgese , Derbeke , and Baky , among others. Rivers in the mountainous areas are usually frozen between September and May. The world's lowest temperatures for inhabited places have been recorded in this region, and there
