Amazon River

Amazon River 

The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru.^[12]The Mantaro and Apurímac join, and with other tributaries form the Ucayali River, which in turn meets the Marañón Riverupstream of Iquitos, Peru, to form what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro^[13] to form what Brazilians call the Amazon at the Meeting of Waters (Portuguese: Encontro das Águas) at Manaus, the river's largest city.

The Amazon was initially known by Europeans as the Marañón, and the Peruvian part of the river is still known by that name today. It later became known as Rio Amazonas in Spanish and Portuguese, and Amazon River in English.
