Lake baikal frozen

Lake Baikal in Siberia is the world's deepest and oldest freshwater lake, renowned for its crystal-clear ice and frozen landscapes.

About this subject

Lake Baikal is located in southern Siberia, Russia, and holds the title of the world's largest freshwater lake by volume, containing about 23,615 cubic kilometers of water. Estimated at 25 million years old, it is the oldest lake on Earth. In winter, temperatures drop to -20°C or lower, freezing the lake's surface to a thickness of up to 2 meters between January and May. The ice is renowned for its clarity, allowing visibility up to 40 meters deep in some areas.

The freezing process of Baikal is not uniform. Giant ice crystals, cracks, and methane bubbles trapped in the ice create a surreal landscape. The region hosts over 2,500 species of plants and animals, 80% of which are endemic, including the Baikal seal (Pusa sibirica), the only freshwater mammal living exclusively in the lake. This unique biodiversity earned Baikal UNESCO World Heritage status in 1996.

Interestingly, Baikal's ice also serves as a venue for cultural events such as New Year's celebrations and ice-car racing. In winter, the Circumbaikal Railway offers spectacular views of frozen cliffs. Despite its beauty, the ecosystem faces threats from industrial pollution and climate change, affecting the freeze cycle and wildlife.
