Lake baikal frozen

Lake Baikal in Siberia freezes annually, creating one of the world's most iconic landscapes with clear ice up to 2 meters thick.

About this subject

Lake Baikal, located in Eastern Siberia, Russia, is the world's deepest and oldest freshwater lake, estimated at 25 million years old with a maximum depth of 1,642 meters. During winter, its waters completely freeze, forming an ice layer that can reach 2 meters thick. This natural phenomenon transforms the lake into a vast ice plain, often marked by fissures and unique crystalline shapes called ice hummocks.

The exceptionally pure water of Baikal allows the ice to become transparent, revealing striking blue hues and textures. This freezing process occurs between January and May, with February and March being the prime months for observation. The frozen surface becomes so robust that it supports vehicles and even the famous Baikal-Amur railway passing through the region.

Beyond its geological significance, Lake Baikal hosts unique biodiversity, with about 80% of its species endemic. During the freeze, life continues beneath the ice, including the Baikal seal (Pusa sibirica), the only exclusively freshwater seal in the world. The ice also holds cultural importance for local communities, who hold festivals and pilgrimages on the frozen surface.

Lake Baikal has been a UNESCO World Heritage site since 1996 and holds approximately 20% of the world's unfrozen freshwater. Its preservation is vital for global ecological balance, and the seasonal ice attracts scientists and tourists keen to study and witness this rare and impressive natural phenomenon.
