"In 1996, author and photographer Michael Collier set out in his forty-year-old Cessna seeking an expanded understanding and perspective on the Colorado River basin - a region spanning the states of Wyoming, Utah, Colorado, Nevada, California, Arizona, and New Mexico - which he had come to know intimately through twenty-five years of river running. Twelve thousand photographs and more than a year later, Collier had learned another way of knowing that magnificent landscape and now shares his altered vision in Water, Earth, and Sky: The Colorado River Basin." "One hundred forty images are accompanied by six essays, written by experts in various fields of natural history and ecology, that illuminate chosen aspects of this landscape."--Jacket.
