Reply to comment by c0reboarder in TIL Lake Baikal is located in southeast Siberia and is the oldest and deepest lake in the world, at 25 million years old and 1,700 meters deep. It contains 20% of the world's unfrozen freshwater and is home to a rich and unusual freshwater fauna that is of significant value to evolutionary science. by wisely_lined56

forget lake superior ..

> [Baikal contains] 22–23% of the world's fresh surface water, more than all of the North American Great Lakes combined

It's a bit larger than Belgium, so only the 7th largest by surface area

> It is also the world's deepest lake, with a maximum depth of 1,642 metres (5,387 feet; 898 fathoms), and the world's oldest lake,[9] at 25–30 million years.

It's the part of ancient rift valley that got filled up with miles of sediment and water
