GREAT NATURE -- Russia's Heart of Fire: The Kamchatka Peninsula

Russia's Kamchatka Peninsula is located in the Pacific Ring of Fire where most of the world's volcanoes can be found. It's a land densely clustered with volcanoes -- many still active. While making this program, the camera crew was able to capture footage from the sky and on the ground. They even got very close to the lava dome of the most dangerous volcano in Eurasia, and fumaroles -- fissures that release steam and volcanic gases. In addition, this adventure includes a visit to a mysterious caldera that creates a number of different minerals. Take a look at this peninsula, pulsating with the primal rhythms of the planet.
