A Walk in the Park: The True Story of a Spectacular Misadventure in the Grand Canyon by Kevin Fedarko
This book is by the same author of the well known "Emerald Mile". However, this is story a 'through hike' of the grand canyon, not the usual rim to rim hike, but hiking the length of the grand canyon following the Colorado from Lee's Ferry to where the river starts to enter Lake Mead. This is a tremendously difficult hike that has been completed by only a handful of people. The author and his photographer friend Pete started the hike fairly unprepared, and with the help experiences friends were able to accomplish their goal.
Along the way the history of through hikers, of the history of the national park and the story of the native people who have lived in the canyon for millenia. Also explored is the uncertain future of the canyon and its use and misuse.
The Emerald Mile: The Epic Story of the Fastest Ride in History Through the Heart of the Grand Canyon, was first published in 2014. Specifically this is the story of the fastest boat to travel through the Grand Canyon on the Colorado, but it is also the history of the rafting business that developed on the river. The many colorful personalities that made up the river guides are described, and of course these are a group of outsiders who lived a unique life on the river.
