Marañón River Flowing Through Peruvian Amazonia4.8S 76.5W
The Marañón River rises about 160 km to the northeast of Lima, Peru, flows through a deeply-eroded Andean valley in a northwesterly direction, along the eastern base of the Cordillera of the Andes. Barred by reefs, and full of rapids and impetuous currents, the Marañón has never become a commercial avenue. After its confluence with the Ucayali River, the Marañón is given the name of the Amazon River.
Upon opening the full orthorectified image, a small area of hills can be seen at the bottom left. This image focuses on the river after it has passed the Pongo de Huaracayo (or Guaracayo); after this point the hills gradually disappear into flat plains. For a distance of about 30 km (20 miles) the river is full of islands, and there is nothing visible from its low banks but an immense forest-covered plain known as the selva baja (“low jungle”) or Peruvian Amazonia.
