As can be seen from the image, the Amazon has many tributaries. The numerous thinner lines show the many remnants of prior channels of this highly mobile river. The reflected sunlight even shows numerous ponds which are usually not visible due to the dense forest cover in central Amazonia. Santarém is bordered by the Amazon and the Tapajós rivers. Both run along many kilometers in the front of the city, side by side, without mixing. Amazon’s milky colored water carries sediment from the Andes in the East, while the Tapajós’s water is somewhat warmer and has a deep-blue tone. This phenomenon is called “The meeting of the waters” by the locals.

The local scenery on the ground is as follows.
