Lena River
The Lena 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 flows north-east and traverses the Lena-Angara Plateau, then is joined by three tributary rivers: (i) the Kirenga, (ii) the Vitim, and (iii) the Olyokma. 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 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 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, the most important being the Bykovsky channel, farthest east.
