Lake Baikal is a rift lake in Russia, located in eastern Siberia, between Irkutsk Region to the northwest and the Buryat Republic to the southeast. The Baikal is the world's deepest lake. It is considered to be the world's clearest lakes and the world's oldest lake. It is the seventh largest lake in the world by surface area. A piece of geography…
A piece of maths… With its depth of 1620 meters Baikal is the deepest of all lakes and of many seas in the world. This is why a native Siberian does not approve it if you call the Baikal “a lake”. "The glorious sea" - this is how it is called here. Lake Baikal accounts for nearly 19 percent of all world`s fresh water, contained in all the world lakes. Another wonder of Baikal is its age. Lake Baikal has been “living” for 25 million years!
A piece of literature … You probably heard a tale about “an old man” Baikal and his beautiful “daughter” Angara who fell in love with the giant Enisey against the will of her father and ran away to him. Angry Baikal, the tale says, threw a rock which is still there and people call it the Shaman stone. Angara is the only river which flows out from Lake Baikal but nearly five hundred rivers flow into the lake.
Welcome to the Baikal! Lake Baikal Kenton M. Stewart I tried to get a sense of the wonder of Baikal, but its majesty was just too great for words to fit it all. I thought about its beauty and its volume besting all. It’s hard to know just where to start when thinking of Baikal. For over 20 million years unique forms have evolved. The lake’s a bank of DNA with secrets not yet solved. The bio-diversity, of forms both large and small, shows that “survival of the fittest” is the case in Lake Baikal. So let’s hear it for the inverts, fish, and even for the seal, and all those plants and species where endemic forms are real. For Baikal is not a treasure for the locals there to hide, or even for one country using it to gain some pride. But the lake is a treasure for the whole world to preserve, yet if it’s not protected… then it’s one we don’t deserve. Economic exploitation, a boon and yet a curse, will take a toll on Baikal…not for better, just for worse. So how can we preserve Baikal and show we really care? That’s a question that will haunt you… once you have been there. Seasons come and seasons go in ancient Lake Baikal. I’m in wonder of that treasure. I’m in love with Lake Baikal.
