The thunder tree

When people connect with nature, they do so in a specific place, and "The Thunder Tree" shows how that connection can change a life forever, how roots in the earth can be as important as roots in a family. For Robert Pyle, that place was the Highline Canal in Denver, Colorado. When he first discovered it as a boy in the 1950s, the canal was largely a wasteland, but it became his sanctuary, the place where he developed a passion for the natural world. Pyle argues eloquently that if we fail to preserve our opportunities to explore nature, we will diminish our lives and our culture immeasurably.
