商品簡介
Geologists Abbott and Cook (Prescott College, Prescott, AZ) present the Grand Canyon though scientists' eyes for rim walkers, day hikers, and serious backpackers. An overview introduces readers to the area's geological history, followed by detailed narratives of 18 hikes. For each hike the authors explore a geological theme, focusing on aspects of the canyon's evolution that are particularly well-illustrated along its length. Basic information such as trail length, elevation change, and difficulty level starts each chapter. Thoroughly illustrated with b&w photos and diagrams as well as 20 color plates.
