Siberian Forest
The wooded uplands west of the Lena lie between the headwaters of the Lower Tunguska and the tributaries of the Vitim country. They form part of the vast Central Siberian Plateau, where coniferous forest covers hills and river valleys. The Lower Tunguska takes a long course towards the Yenisei, while streams on the other side of the divide reach the Lena. Snow and ice dominate the landscape through the long winter.
