Central Siberian Plateau
The North Siberian Lowland (), also known as Taymyr Lowland (Таймырская низменность), is a plain with a relatively flat relief separating the Byrranga Mountains of the Taymyr Peninsula in the north from the Central Siberian Plateau in the south. To the southeast of the Olenyok basin the lowland merges with the Central Yakutian Lowland.
