Lake Baikal, Russia

Lake Baikal is a rift lake located in Russia situated in southern Siberia between the federal subjects of Irkutsk Oblast to the northwest and Buryatia to the southeast.

Baikal is home to hundreds of plant and animal species, many of which are peculiar to the region. It is also home to Buryat tribes, who breed goats, camels, cattle, sheep, and horses on the lake's eastern side[15], where the mean temperature ranges from a winter minimum of 19 °C (2 °F) to a summer maximum of 14 °C (57 °F).

Baikal, located in south-central Siberia near the Mongolian border and surrounded by mountains, forests, and wild rivers, is a vast and spectacular natural beauty. It is the world's oldest and deepest freshwater lake, holding around 20% of the world's unfrozen surface freshwater. It really has more water than all of the Great Lakes combined. It is also one of the purest lakes in the world, and it is considered to be the world's oldest, dating back 25 million years.

The lake is home to more than 2,000 species of plants and animals. Two-thirds of which can be found nowhere else in the world, like the earless nerpa—one of the world's only freshwater species of seal.
