"The science of the Earth in all its splendor." Over the Rivers is the second volume in the exciting "Aerial View of Geology" series (the first was the highly praised "Over the Mountains"). As as a geologist, one of America's premier aerial photographers and a gifted science writer, Michael Collier is exceptionally well qualified to present these spectacular landscapes and stunning aerial photographs that vividly demonstrate geological processes. Vivid text and clear captions guide readers through the exciting photographs, enhancing their understanding of fundamental geological processes. Collier explores, for example: How a 6,000-foot-deep canyon was carved out by the erosive power of a single river How violent tectonic forces millions of years ago vaulted a river over a mountain Why one river takes its time meandering, another suddenly drops over a cliff, and a third slowly separates into a sprawling delta. Over the Rivers inspires as it informs, and dazzles as it enlightens.
