Lake Baikal Situated in south-east Siberia, the 3.15-million-ha Lake Baikal is
the oldest (25 million years) and deepest (1,700 m) lake in the world.
It contains 20% of the world’s total unfrozen freshwater reserve. Known
as the ‘Galapagos of Russia’, its age and isolation have produced one of
the world’s richest and most unusual freshwater faunas, which is of
exceptional value to evolutionary science.
