Carving Grand Canyon: Evidence, Theories, and Mystery
by Wayne Ranney
Grand Canyon is one of Earth’s most recognizable landscapes. Geologists have studied the canyon for more than 150 years, yet a single definitive answer for how or when the canyon formed remains elusive. Many aspects of the canyon’s formation are known, and new studies, using modern techniques, can tease out the cryptic clues that hold answers. Grand Canyon was carved largely by the erosive power of the Colorado River, but just how the river accomplished its task is a spellbinding story that is sure to appeal to your sense of discovery.
Carving Grand Canyon provides a clearly written synopsis of the intriguing ideas and innovative theories that geologists have advanced about canyon formation. Updated with ideas that emerged from the most recent symposium on Grand Canyon geology, this new edition reflects the latest thinking on the canyon’s formation, supported by dozens of new illustrations and photographs and a foreword by noted Grand Canyon author Stephen Pyne. The story of a fascinating landscape is told in an engaging style that non-scientists will find inviting. The story’s end, however, remains a mystery yet to be solved.
