Bii
Bii-Khem, the “great river” in Tuvan, rises in the mountain country of eastern Tuva. Flowing from Lake Kara-Balik through the broad Todzha basin, it gathers tributaries including the Toora-Khem, Khamsara and Systyg-Khem. Its course continues west to meet the Little Yenisei, forming the Upper Yenisei. Forests, lakes and volcanic highlands surround the upper river and its many streams.
