The world's largest river by

The world’s largest river by volume, drainage basin, number of tributaries, and possibly length begins “high in the Peruvian Andes as a thin sheet of crystal water flowing down the side of a rock wall”. A spot on a slope of Nevado Mismi meets both definitions of the source of the Amazon, being the furthest point in the watershed from which water flows continuously as well as the furthest point from which water could possibly flow into the ocean. A five-nation National Geographic Society expedition pinpointed the source of the Amazon using GPS technology.
