The West Siberian Plain (Russian: За́падно-Сиби́рская равни́на) is a large plain that occupies the western portion of Siberia and Russia, between the Ural Mountains in the west and the Yenisei River in the east, and by the Eastern Sayan Mountains and the Baikal Mountains on the south. It has been described as the world's largest unbroken lowland—more than 50 percent is less than 330 feet (101 m) above sea level[1]—and covers an area of about 2.6–2.7 million km² which is about one third of Siberia,[2] extending from north to south for 2,400 km, from the Arctic Ocean to the foothills of the Altay Mountains, and from west to east for 1,900 km from the Yenisei River to the Ural Mountains.

Geology

The West Siberian Plain consists mostly of Cenozoic alluvial deposits and is extraordinarily flat. A rise of fifty metres in sea level would cause all land between the Arctic Ocean and Novosibirsk to be inundated (see also Turgai Straits, West Siberian Glacial Lake). Many of the deposits on this plain result from ice dams; having reversed the flow of the Ob and Yenisei Rivers, redirecting them into the Caspian Sea, and perhaps the Aral Sea as well. It is very swampy and soils are mostly peaty Histosols and, in the treeless northern part, Histels. Mammals are the dominant creatures of Cenozoic. ... An alluvial deposit is an accumulation of alluvium (sediment), sometimes containing valuable ore and gemstones, or simply consisting of gravel, sand, or clay, in the bed or former bed of a river. ... For considerations of sea level change, in particular rise associated with possible global warming, see sea level rise. ... Novosibirsk (Russian: , pronounced ) is Russias third largest city, after Moscow and Saint Petersburg, and the administrative center of Novosibirsk Oblast. ... The West Siberian Glacial Lake is a postulated proglacial lake formed when the Arctic Ocean outlets for each of the Ob and Yenisei rivers are believed to have been blocked by the Barents-Kara Ice Sheet during the Weichselian Glaciation, approximately 80,000 years ago. ... lauren rocks my world The river splits into more than one arm, especially after joining the large Irtysh tributary at about 69° E.

Large regions of the plains are flooded in the spring, and marshlands make much of the area unsuitable for agriculture. The principal rivers in the West Siberian Plain are the Ob, Irtysh, and Yenisei. There are many lakes and swamps, as well as large petroleum and natural gas reserves.
