Book excerpt: "Focusing on the saddening, maddening example of Glen Canyon, Jared Farmer traces the history of exploration and development in the Four Corners region, discusses the role of tourism in changing the face of the West, and shows how the "invention" of Lake Powell has served multiple needs. He also seeks to identify the point at which change becomes loss: How do people deal with losing places they love? How are we to remember or restore lost places?"--BOOK JACKET.
