West of Lake Baikal, the world's deepest lake, is an active volcano which few people have ever heard of. Known as Jom Bolok, this volcano last erupted in the 12th century, with another recent eruption ranking in as one of the planet's largest effusive eruptions in the last 10,000 years. This is the story of the Jom Bolok volcano, which has produced several glacial river valley filling lava flows in the last 15,000 years.
