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.

Margaret's guidebook has been the only guidebook to the trails of this area for more than 30 years. Updated and expanded for the second time in 2020. Both popular areas like the Bighorn Crags near Challis and remote areas like the Big Creek drainage near Yellow Pine are included in the book. Several of the roads to trailheads, such as the road to Sleeping Deer and the Nez Perce Trail Road are adventurous in themselves and 4-wheel drive is advised for some of them.
