Brazil – November 10th, 2012

This image shows the Tapajós River (visible as a thick, blue band) joining the  Amazon River (brown with sediments, meandering horizontally across the image center). The Tapajós runs through a humid, hot valley and pours into the Amazon River 500 miles above Pará.  It is about 1200 miles long. For its last 100 miles it is from 4 to 9 miles wide and much of it very deep. The valley of the Tapajós is bordered on both sides by bluffs. They are from 300 to 400 feet high along the lower river; but a few miles above Santarém, they retire from the eastern side and do not approach the Amazon flood-plain until some miles below Santarém. Upon opening the full image, the mouth of the Amazon can be seen to the northeast.
