This is the guidebook to the Colorado River used by the characters in Will Hobbs's book "Downriver".

The epic story of the fastest boat ride in history, on a hand-built dory named the "Emerald Mile," through the heart of the Grand Canyon on the Colorado river.

Kim Crumbo, a river ranger at Grand Canyon National Park, has written a guide to the rich human history of the river and its canyon. Every rapid and other point of interest is discussed and clearly marked.

The majesty of the Grand Canyon is celebrated from the Colorado River as it continues to carve America's natural wonder from a mile below the rim. As one of the Wonders of the World and the most iconic national park in America, the Grand Canyon enthralls six million visitors each year. Only a small fraction of those people, however, have the privilege of experiencing the canyon by rafting down the Colorado River. The Grand Canyon captures and evokes the power of that journey from the drama of the rapids and the immeasurable scale of the canyon walls to the subtle rock patterns and varied life forms. What started as an exceptional opportunity for Tom Blagden to raft through The Canyon in 2006 with Rod Nash at the oars has evolved into a passionate photographic pursuit that still continues. The route--the River--is the same every time but the experience constantly variable and deeply profound. Rafters never tire of it and, if anything, feel more in awe of the Canyon's magnificence with each trip. Tom Blagden's images and Rod Nash's essay reveal the canyon from a different perspective portraying what it's like to be on the river and immersed a mile deep, surrounded by rock almost half the age of the earth. On the centennial of Grand Canyon National Park it seems only fitting that we journey together to this unique place through the pages of this astonishing book. The book weaves a wondrous adventure that will bring readers along on a journey while raising questions about the significance of a national park and an iconic American river and how to sustain them for generations to follow.
