Geologist Andrés Ruzo first heard about the boiling river as child, but it was always thought of as mythical. It was considered “a place of spirits.” But when Ruzo’s aunt insisted a boiling river existed in Peru, he set out to find it. Now, Ruzo is the first scientist to be given the blessing of the local shaman to study the boiling river. Ruzo talks about the mysterious nature of the boiling river on the latest episode of the TED Radio Hour.
