From Wikipedia
Jom-Bolok, also known as Volcano Valley and East Sayan Volcanic Field, is a volcanic field in Russia, 200 kilometres (120 mi) west of Lake Baikal. It is part of the Baikal rift zone which is also responsible for volcanism elsewhere around Lake Baikal. The volcanic activity has generated long lava flows and cinder cones. One of the lava flows is 70 kilometres (43 mi) long and has a volume of 7.9 cubic kilometres (1.9 cu mi).
