Hot springs, volcanoes, and other fiery portals to the Earth’s core have stoked fear and awe since the earliest humans. When geothermal scientist and National Geographic Explorer heard a family story about a river that boils, he decided to investigate. We go on assignment into the Peruvian jungle to find this one-of-a-kind place, document its source, and meet the people who hold it sacred.
Andrés Ruzo is a geothermal scientist, educator, and science communicator best known for his work at the Boiling River, deep in the Amazon. He works with local communities and Indigenous groups in the central Peruvian Amazon through educational and sustainable economic initiatives. Ruzo holds degrees in geology and finance and will soon finish his Ph.D. in Earth Sciences. He has also hosted a National Geographic Latin America television show Misterios del Inframundo (Mysteries of the Underworld).
