Skaters glided gracefully across the frozen surface of Lake Baikal, the world’s deepest freshwater lake, taking in the breathtaking winter scenery while skating across huge sheets of ice dozens of feet thick. The frozen Siberian lake offers a perfectly clear view of the lake bottom as the frozen ice is as clear as glass in many places. Ice skating from one end to the other takes about 2 weeks! How would you like to skate on this lake of glass?
