East European Plain
The East European Plain (also called the Russian Plain, predominantly by Russian scientists, or historically the Sarmatic Plain) is a vast interior plain extending east of the Polish Plain (Middle European), and comprising several plateaus stretching roughly from 25 degrees longitude eastward. It includes the westernmost Volhynian-Podolian Upland, than the Central Russian Upland, and on the eastern border, encompassing the Volga Upland. The plain includes also a series of major river basins such as the Dnepr Basin, the Oka-Don Lowland, and the Volga Basin. Along the southernmost point of the East European Plain are the Caucasus and Crimean mountain ranges. Together with the North European Plain covering much of central Poland, Estonia, Latvia and Lithuania, it constitutes the European Plain, the mountain-free part of the European landscape.
The East European Plain covers all or most of the Baltic states, Belarus, Ukraine, Moldova, Romania, and the European portion of Russia. The plain spans approximately 4,000,000 km2 (2,000,000 sq mi) and averages about 170 m (560 ft) in elevation. The highest point of the plain, located in the Valdai Hills is 346.9 metres (1,138.1 ft).
