Two books in one! This 355-page book is the bible of cross-country skiing, snowshoeing, snowboarding and backcountry skiing in Idaho, the Tetons and Yellowstone National Parks. It includes descriptions of hundreds of cross-country ski and snowshoe trails. Backcountry aficionados will also find it invaluable with beautifully done aerial illustrations detailing snowboard and backcountry ski routes in some best terrain in the west. And the book is filled with stories, honoring and retracing the rich traditions of western winter travel. To top it off, it has been carefully and lovingly designed which is obvious by its pleasing graphics, easy-to-use maps, enticing photography, and overall visual appeal. All in all, this is truly a model guidebook.
