The main source of the Amazon River, the largest river in the world by discharge,[1] has been a subject of exploring and speculations for centuries and continues to cause arguments even today. Determining the origin of the Amazon River has evoked broad debates among scholars, explorers, and travelers all over the world. Different definitions of a river's source have been used and continue to be used. Generally, four main criteria can be applied to determine the main source of a river: source flow rate, source length, watershed area of the source, and an altitude of its spring.[2] At present, the Amazon River is not considered to have one unique source but a number of headstream areas. These are headwaters of three different Peruvian rivers that can be found in the high Andes: the Marañón, the Apurímac, and the Mantaro.
