Icy Surface of Frozen Lake Baikal, Russia53.1N 107.6E
During the harsh Siberian winter, Lake Baikal, the world’s largest, oldest and deepest freshwater lake, freezes over. The surface of the frozen Baikal is covered in fields of “hummocks”, small hills of ice rubble.
Beneath the ice surface, geothermic springs and seismic activity cause localized melting that sometimes may weaken the ice to form holes. However, the average ice on Lake Baikal is over 1 meter and a half thick, which allows trucks and vehicles up to 10 ton in weight to drive on the ice.
