Trickster coyote, in western Indian lore, is the creative earth spirit. To Sullivan, making a 1360-mile west-to-east walk through Oregon, the coyote represents wilderness and the reason for preserving nature. Touching 18 wilderness areas and crossing four mountain ranges, the author scouted a route later recommended for the New Oregon Trail. His daily journal tells about his solo walk, discusses the ecosystems he observed, and describes the various attitudes toward wilderness held by individuals met en route. Two major enemies of western wilderness, timbercutting and cattle grazing, are neither ignored nor blasted. For fans of Edward Abbey, Colin Fletcher, John Hillaby, and Edgar Garvey. Paula M.
