Your Guide to the Grand Canyon True North Series

Exploring the Grand Canyon is a one-of-a-kind adventure. It is a World Heritage Site and one of the most amazing features on the face of the planet. The size and majesty of the Canyon is overwhelming, regardless of how many times you have viewed it, how many trails you have hiked, or how many river miles you have traveled. It is also a mystery! Most will agree that the Grand Canyon was carved by water. But how and when is where the mystery lies. Was it formed slowly over millions of years or quickly in a catastrophic event? This debate falls into two camps, which hold to vastly divergent worldviews. This True North Guide examines the geological and ecological evidence and lets you decide which of those worldviews is best supported by the data. *Contains 26 fold-out pages with maps, special overlook features, and more! *Discover the Canyon s wildlife, vegetation, fossils, geology, and history!"
