The narratives in this book are of journeys made in three wildernesses - on a coastal island, in a Western mountain range, and on the Colorado River in the Grand Canyon. The four men portrayed here have different relationships to their environment, and they encounter each other on mountain trails, in forests and rapids, sometimes with reserve, sometimes with friendliness, sometimes fighting hard across a philosophical divide.
