The "life" of the San Juan River is traced in this readable volume, which will appeal to the general public, as well as students and professionals interested in the earth sciences, the environment, anthropology, and US history. The River's geology is described in detail, before Aton (Southern Utah U.) and McPherson (College of Eastern Utah) turn to an in-depth study of the civilizations that lived by the River from prehistory through the present and the changes the River and the life in and around it endured as a result. Includes b&w photos. Annotation c. Book News, Inc., Portland, OR (booknews.com)
