There is always high interest in things around the globe that reach the highest or lowest peaks. Whether it is the highest building or the deepest hole there is always a captivating story behind it. However, Lake Baikal is a bit different.
Being the deepest and oldest lake in the world would be the main attraction but what is even more interesting is that most of the time the lake is frozen solid. Very rarely has the lake melted and even when the ice happened to be very thin the temperatures were still too cold for anyone to have a dive to find the bottom.
The lake is estimated to be 1,637 meters deep and around 25 million years old. An interesting fact is that this lake contains a fifth of the world's freshwater reserve at around 23,000 cubic kilometers (14,200 cubic miles) of water.
