Smithsonian Atlas of the Amazon;

The Amazon River flows more than 4,000 miles through the world's greatest rainforest, into the Amazon delta, and finally into the Atlantic Ocean. This extraordinary atlas is the first comprehensive view of not only the Amazon River but also its thirteen major tributaries. More than 150 color maps and nearly 300 vivid photographs provide spectacular views of the river and rainforest. Along the way, the authors explore many intriguing topics such as why some of the Amazon’s tributaries have black water, what happens when the freshwater of the Amazon reaches the salty ocean, and why we all should be concerned about the deforestation that contributes to the loss of species biodiversity.
