Siberian Forests
The forests of the Central Siberian Plateau spread south of the Lower Tunguska, across a broad country of ridges and river valleys. Larch and other conifers cover much of the taiga, while rivers drain the plateau towards the Yenisei. The Lower Tunguska has a winding upper course and cuts through narrower rocky valleys farther downstream. Winter ice and spring floods mark the great seasonal changes of its northern basin.
