This book introduces children to the nation's watershed, the Continental Divide, and how snowmelt forms the headwaters of the rivers and streams that bring life to the land below on the Rocky Mountain's Western Slope. The entire water cycle is described from evaporation to glacier formation and the various life zones that water runs through on its way from alpine tundra to the rich farmland of the Western Slope is detailed in exquisite drawings.
