Låter högst osannolikt att en jesuitpräst kunde hitta rätt
redan år 1707:
The source of the Marañón River had been considered the main source of the Amazon River for a number of centuries. This source was determined by a Czech Jesuit priest named Father Samuel Fritz who sailed the Amazon River from its mouth upstream and drew the first map of the Amazon River basin.
Han hade bara en båt och handritad karta. Med modern teknik måste det gå att hitta rätt källa med större säkerhet.
Bra fråga av TS.
Wiki: "The main source of the Amazon River is therefore difficult to determine, so it is correct to talk about several of its source areas."
Va? Klart det går att räkna ut om man har en
högupplöst 3D-karta.
