The river that BOILS its victims alive: Legendary four-mile long waterway is discovered deep in the heart of the Amazon

A mysterious, four-mile long river deep in the heart of the Amazon is so hot that it boils. The river has long been a legend in Peru, and when geoscientist Andrés Ruzo's head about it, he thought such a phenomenon was impossible. It would require a huge amount of geothermal heat to boil a river, and the Amazon far from any active volcanoes. But then, Ruzo saw the legendary boiling river with his own eyes. For some reason, the river has escaped much scientific scrutiny. But Ruzo is on a mission to change that. He has published a book , 'The Boiling River: Adventure and Discovery in the Amazon,' that publicises the river for the first time.
