Lena River

  

This article is about the Lena river. See Lenna for a description of the famous image used in digital image processing.

The Lena River in Siberia is the 11th longest river in the world and has the 9th largest watershed. It flows northeast and then north from its source in the Baikal Mountains south of the Central Siberian Plateau, and it empties into the Arctic Ocean via the Laptev Sea. At the mouth of the Lena River is a delta that is about 250 miles wide. The delta is frozen tundra for about 7 months of the year, but spring transforms the region into a lush wetland for the remainder of the year. Part of the area is protected as part of the Lena Delta Wildlife Reserve.

The Lena has the unusual distinction of appearing to be the longest river in the world when viewed on a map using a Mercator projection, the most common method of displaying the spherical earth on a flat surface, due to that projection's tendency to exaggerate the size of areas near the poles. (The Amazon and Nile both cross the equator.)


Lena (Russian: Ле́на) is a river of Siberia, rising at the height of 1640 m in the Baikal Ridge, 20 km west side of Lake Baikal. Wheeling round by the south, it describes a semicircle, then flows north-north-east and north-east, being joined by the Kirenga and the Vitim, both from the right; then it flows east-north-east as far as Yakutsk, where it enters the lowlands, after being joined by the Olyokma, also from the right. From Yakutsk it goes north until joined by its right-hand affluent the Aldan, the Verkhoyansk Range deflects it to the north-west; then, after receiving its most important left-hand tributary, the Vilyui, it makes its way nearly due north to the Laptev Sea, a division of the Arctic Ocean, disemboguing south-west of the New Siberian Islands by a delta 10,800 sq. m. in area, and traversed by seven principal branches, the most important being Bylov, farthest east. The total length of the river is estimated at 4310 km (2860 m), 3380 km (2100 m.) of which is navigable. The delta arms sometimes remain blocked with ice the whole year round. At Yakutsk, navigation is generally practicable from the middle of May to the end of October, and at Kirensk, at the confluence of the Lena and the Kirenga, from the beginning of May to about the same time. Between these two towns there is during the season regular steamboat communication. The area of the Lena river basin is calculated at 2,500,000 km² (805,000 sq. m.). Gold is washed out of the sands of the Vitim and the Olyokma, and tusks of the mammoth are dug out of the delta.

The majority of the researchers believe that the name of the river Lena has been acquired from the original Even-Evenk name Elyu-Ene, which means "the Large River".

Vladimir Ilyich Ulyanov is believed to have named his alias after the river Lena: Lenin.
