Tunguska

The lower course of the Lower Tunguska approaches the Yenisei through the forests of central Siberia. The river drains a vast plateau and passes rocky gorges and rapids before its waters join the greater river. In the early seventeenth century Russian fur traders and servicemen travelled up the Tunguska from the Yenisei, following a route through country inhabited by indigenous peoples. Seasonal ice and spring floods shaped the passage.
