The Mystical Boiling River of the Amazon

(via Great Big Story) When Andrés Ruzo was a boy, his grandfather would tell him tales of a mythical city of gold deep in the heart of the Peruvian jungle. Though never believing the stories to be true, the legend of the lost city stuck with him into adulthood. Years later, as a geothermal scientist, Ruzo decided to investigate. To his surprise, he discovered an incredulous river deep in the Amazon, with water hot enough to kill a human.
