The source of the Amazon River is a small lake in the Peruvian Andes called Laguna McIntyre. It is named after explorer Loren McIntyre. One of the legendary stories told about him is an encounter he had in the late 1960s with an obscure tribe in the Amazon forest called the Mayoruna. He discovered that he could communicate telepathically with them, even though they didn't share a common language. The story was recounted in a book called *Amazon Beaming* by Petru Popescu. It was also made into a play called *The Encounter.* National Geographic spent 20 years trying to find the source of the Amazon River. They finally gave the assignment to McIntyre in 1971. After several months and a 6500-mile journey, he claimed to have discovered it. “It was probably the first time anyone has dared such a journey in an overloaded Cessna 182 w/o radio, w/o filing flight plans, and w/o announcing arrivals or departures,” he wrote. His story was published in the October 1972 issue of National Geographic. His claim was disputed for many years. It was only in 2001 that a 22-person crew using 40,000 GPS readings concluded that “a drop of water from Lake McIntyre flows 4,000 miles to the Atlantic.” As befits a man who could communicate telepathically with an Amazonian tribe, Loren McIntyre had been guided by intuition. He said the mountain had called to him. --- **Source** https://www.nationalgeographic.com/magazine/plus/lost-and-found/amazon-encounter-explorer-photographer/
