西シベリア平原
The region directly east of the West Siberian Plain is the Central Siberian Plateau, which extends eastward from the Yenisei River valley to the Lena River valley. The region is divided into several plateaus, with elevations ranging between 320 and 740 meters; the highest elevation is about 1,800 meters, in the northern Putoran Mountains. The plain is bounded on the south by the Baikal Mountains system and on the north by the North Siberian Lowland, an extension of the West Siberian Plain extending into the Taymyr Peninsula on the Arctic Ocean.
