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.
