The treasure of Lake Baikal is safely kept in the heart of the Eurasian continent. And like a genuine treasure, the lake is surrounded by guards in the form of mountains and hills.

As we know, the total area of this crescent-shaped lake is about 12 250 sq mi - that is equal to the land area of Belgium. Its maximum depth is 5,387 ft.

Besides being the deepest one, Lake Baikal also appears to be the most ancient. The lake's age is estimated by scientists at 25-35 million years.
