Scientists are still divided over the origins of Baikal. Traditionally, the lake is believed to be 25-35 million years old. This makes Baikal unique, as most of lakes, especially glacial lakes, usually only exist for 10,000-15,000 years and then are filled with silt or turn into swamplands.

According to a legend, Father Baikal had 366 river sons and one daughter river – Angara. All the son rivers ran into the lake to replenish its waters. But the daughter fell in love with the Yenisei and ran from her father. Baikal was mad at Angara. He threw a large piece of a cliff at her and cursed her. This piece of rock, called the Shaman rock, is located near the source of the Angara River and is believed to be its first spring.
