Lake baikal frozen

Lake Baikal in Siberia is the world's deepest and oldest freshwater lake, with crystal-clear waters that freeze into a unique landscape.

About this subject

Lake Baikal is located in southern Siberia, Russia, and holds the title of the deepest lake on Earth, reaching a depth of 1,642 meters. Its estimated age of 25 to 30 million years also makes it the oldest, hosting a unique ecosystem with over 2,500 endemic species, such as the Baikal seal (Pusa sibirica). During the harsh winter, from January to May, the lake's surface freezes completely, forming an ice layer that can be up to 2 meters thick. The exceptional transparency of this ice allows visibility to depths of up to 40 meters, creating phenomena like frozen methane bubbles and blue ice crystals. The area has been a UNESCO World Heritage Site since 1996. For the indigenous Buryat people, Lake Baikal is a sacred place, associated with legends and rituals. Winter tourism attracts visitors for ice trekking, diving, and wildlife observation. Despite its beauty, the lake faces environmental threats such as global warming and industrial pollution, particularly from the Baikalsk Pulp and Paper Mill, which was closed in 2013. Scientific studies monitor changes in ice and biodiversity to understand climate impacts.
