About this Book
Teamed with scientists and other naturalists, Zwinger was part of an ongoing study of change along the Colorado. In all seasons and all weathers, in almost every kind of craft that goes down the waves, she returned to the Grand Canyon again and again to explore, look, and listen. From the thrill of running the rapids to the wonder in a grain of sand, her words take the reader down 280 miles of the "ever-flowing, energetic, whooping and hollering, galloping" river.
