Baikal

Lake Baikal fills a deep rift basin in the mountains of southern Siberia. It is the deepest lake in the world and contains an immense volume of fresh water. The Selenga brings water into its southeastern side, while the Angara carries water out toward the Yenisei. Baikal’s long isolation has fostered a remarkable array of plants and animals found nowhere else, including the freshwater Baikal seal.
