Orellana descends the river to the Atlantic

node

A detachment of a Spanish expedition under Francisco de Orellana becomes separated from the main party in the eastern Andes and is carried downriver, reaching the Atlantic in 1542 - the first recorded European transit of the river's length. The chronicle of the voyage describes densely populated riverbanks with continuous settlement, a description long dismissed as embellishment and partially rehabilitated by later archaeology and soil evidence. The name Amazon derives from an episode in that account.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
