Originating at an elevation of 1,640 meters (5,381 ft) at its source in the Baikal Mountains south of the Central Siberian Plateau, 7 kilometres (4 mi) west of Lake Baikal, the Lena flows northeast, being joined by the Kirenga River, Vitim River and Olyokma River. From Yakutsk it enters the Central Yakutian Lowland and flows north until joined by its right-hand tributary the Aldan River and its most important left-hand tributary, the Vilyuy River. After that, it bends westward, flowing alongside the Kharaulakh Range, part of the Verkhoyansk Range, and then making its way nearly due north to the Laptev Sea, a division of the Arctic Ocean, emptying south-west of the New Siberian Islands by the Lena Delta – 30,000 square kilometres (11,583 sq mi) in area, and traversed by seven principal branches, the most important being the Bykovsky channel, farthest east.
