Lake Baikal, Russia (World's Deepest Lake)
Lake Baikal, the world’s oldest and deepest freshwater lake, curves for nearly 400 miles through south-eastern Siberia, north of the Mongolian border. It lies in a cleft where Asia is literally splitting apart, the beginnings of a future ocean. Geologists say Baikal today shows what the seaboards of North America, Africa and Europe looked like as they began to separate millions of years ago.
