"This 2.3 million acre Idaho wilderness is carved by the Salmon River into a maze of deep canyons and rugged peaks. In the third edition, which includes for the first time GPS co-ordinates for the trailheads, 101 trails are described. The Salmon River and its tributaries have carved the Frank Church - River of No Return Wilderness into a maze of deep canyons and isolated peaks. From any high point a gigantic relief map of ridges extends to distant blue crags. The crags and ridges hide cobalt blue lakes and bubbling hot springs. In most sections, the footprints you see will be those of elk and deer, not humans."--Publisher marketing.

Margaret Fuller wrote the first comprehensive guidebook to any Idaho area. In 1979, Trails of the Sawtooth and White Cloud Mountains was first published (The title was changed for this sixth edition to show what the area was called during the campaign for its wilderness.). Since 1979 when the first edition of Trails of the Sawtooth and White Cloud Mountains came out, Margaret has written or co-authored four other hiking guidebooks, three books of natural history and a history of Idaho ski areas. Also she has kept writing new editions of her guidebooks as needed. Her five children have always hiked with her for her books and now her grandchildren help, too.She has hiked more than 6,000 miles on Idaho trails and has given more than 250 slide shows about the subjects of her books. Margaret has been given several awards for her writing and her contributions to the outdoors in Idaho.
