Where along the Rhine does the Nibelung Treasure lie? What river helps mark the prime meridian? Why do people make pilgrimages to the Indian city of Benares? Why is the Mekong called the "Nine Dragon" river in Vietnam? How does the Mississippi divide and unite the United States? These and hundreds of other facts are explored in this wonderfully illustrated atlas of the world's great rivers. Each spread in this book offers a colorful map packed with drawings, figures, and facts. Cities that border the rivers are highlighted, as are distinct flora and fauna, significant natural and human-made features, and fascinating historical details. A "biography" of each river describes where it flows, and its importance to the communities it passes through. Special attention is given to the ecological health of the rivers-those that are thriving and those in danger of losing their valuable habitats.
