Tutonchany

The Tutonchana descends from the northern plateau to join the Lower Tunguska from the right. Its course is about 459 kilometres long, and its basin extends over more than sixteen thousand square kilometres. In the upper reaches it is a mountain river with rapids and a bed of pebbles and boulders. The waters eventually travel west with the Tunguska to the Yenisei, through a country of forest and long winter ice.
