West Siberian Plain
The West Siberian Plain, also known as Zapadno-sibirskaya Ravnina, (Russian: За́падно-Сиби́рская равни́на) is a large plain that occupies the western portion of Siberia, between the Ural Mountains in the west and the Yenisei River in the east, and by the Altay Mountains on the southeast. Much of the plain is poorly drained and consists of some of the world's largest swamps and floodplains. Important cities include Omsk, Novosibirsk, Tomsk and Chelyabinsk.
Geography
West Siberian Plain is located east of Ural Mountains mostly in the territory of Russia. It covers an area of more than 975,000 sq.mi. It has been described as the world's largest unbroken lowland—more than 50 percent is less than 330 feet (100 m) above sea level—and covers an area of about 2.6–2.7 million km² which is about one third of Siberia, extending from north to south for 1490 mi (2,400 km), from the Arctic Ocean to the foothills of the Altay Mountains, and from west to east for 1,180 mi (1,900 km) from the Yenisei River to the Ural Mountains.
