Lake baikal frozen

Lake Baikal in Siberia freezes completely during winter, creating one of the world's largest ice surfaces, up to 2 meters thick.

About this subject

Lake Baikal, located in southern Siberia, Russia, is the deepest freshwater lake on Earth, reaching depths of over 1,600 meters. It holds approximately 20% of the world's unfrozen surface freshwater, a volume comparable to all five North American Great Lakes combined. During winter, from January to May, the lake's surface freezes completely, forming an ice layer that can reach up to 2 meters thick. The ice is remarkably transparent in many areas, allowing a view of the rocky bottom and frozen aquatic plants. Temperatures in the region drop to -30°C, but the ice thickness is enough to support vehicles and even temporary railway tracks. The phenomenon of frozen methane bubbles, created by gases released from algae on the lakebed, forms mesmerizing patterns in the ice. Lake Baikal has been a UNESCO World Heritage site since 1996, recognized for its unique biodiversity, including the Baikal seal, the world's only freshwater seal. The ice features attract researchers and tourists, who can walk, cycle, or drive on the frozen lake, as well as go ice diving. Every winter, the ice breaks into huge blocks with thunderous sounds, a natural spectacle known as "Baikal thunder".
