Book excerpt: This book picks up the Continental Divide Trail in Idaho at the western border of Yellowstone National Park and takes the reader some 900 miles all the way to the Canadian border. From the Beaverhead Mountains in the Bitterroot Range to the Scapegoat and Bob Marshall Wildernesses, Idaho and Montana's most spectacular and remote wild lands fill page after page in a book that fits into your backpack or makes for great reading anytime.You'll have no better companion than the lively and humorous voice of Lynna Howard and the dramatic, breathtaking photography of Leland Howard. Aspects of history, wildlife, geology, and biology are explained along the way. For day hikes, destination hikes, or longer treks for the avid backpacker, this book is a must. This trail is rougher and more challenging than the Pacific Crest Trail or the Appalachian Trail, Lynna writes. A spirit of adventure is the best thing you can pack!
