Yes, that is true! Lake Baikal in Siberia, Russia, is both the oldest (around 25-30 million years old) and the deepest freshwater lake in the world, reaching depths of about 1,642 meters (5,387 feet). It also holds around 20% of the world's unfrozen freshwater, making it a crucial resource and a natural wonder. Lake Baikal is also known for its unique biodiversity, including the Baikal seal, which is found nowhere else in the world.
