This outdoor guide to the interior of Alaska covers 56 outdoor activities, including hikes, bike rides, ski paths, and floats, and is separated into chapters by region. Each listing begins with an outline of useful information such as round-trip distance, duration, total elevation change, difficulty level, best season, useful maps, and contact information for the land manager; following are descriptions of the routes and trails, suggestions for variants from the path and other near-by activities, and precise road and foot directions to the start of each adventure. The extensive introduction to the book includes information on using the guide, the environment (including flora, fauna, and weather), and backcountry travel. The book also includes a bibliography and an index as well as three appendices outlining further trips and adventures, contact information for Alaskan agencies, outdoor groups, and businesses, and a useful chart outlining the type of trips covered in the book by difficulty level. This book is intended to be useful for all skill levels, and there is a fair scattering of activities for all levels. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
