Water is a resource, a recreation, and a requirement for life itself. It is also a sight to behold, whether it's the product of millions of years of geological evolution or a remarkable feat of modern engineering. This aerial excursion whisks you above America's massive lakes, powerful rivers, mind-boggling glaciers, and shape-shifting wetlands as well as its man-made dams and canals. See how our interaction with water has shaped our nation's landscape and its history, and how its importance continues to ripple from coast to coast.
