The West Siberian Plain (Russian: За́падно-Сиби́рская равни́на) is a large plain that occupies the western portion of Siberia in 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 (100 metres) 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, so much so that a rise of fifty metres in sea level would cause all land between the Arctic Ocean and Novosibirsk to be inundated. 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. The Cenozoic Era (IPA pronunciation: ); sometimes Caenozoic Era (in the United Kingdom), meaning new life (Greek (kainos), new, and (zoe), life), is the most recent of the three classic geological eras. ...
