Lake Baikal has formed ...in a rift valley created by the Baikal Rift Zone, a divergent plate boundary. So far geologically, there has been no volcanism associated with the rift underneath the lake, but there are hot springs present both on land and under the lake. Close-by volcanic activity on the Udokan Plateau is believed to be associated with the Baikal Rift.
The climate of the Lake Baikal region averages -19°C in the winter and 14°C in the Summer.
Home to over 1600 species of plant and animal (of which more than 80% are endemic to the region) Lake Baikal was declared a world heritage site in 1996. The Eastern side of the lake is also home to Buryat tribes (The Buryats are the largest indigenous group in Siberia and number around 500,000).
