Almost all of Muir's travels are solitary. The extraordinary scenes he witnesses and the amazing feats of physical strength he engages in are witnessed by few. In fact, Muir's journals include few personal details about himself or anyone else. However, there is one major account of Muir's journeys and adventures in the book that is described by another individual, a Presbyterian Minister named Samuel Hall Young. When Young first travels with Muir. he is just out of college. He meets Muir at a trading post stop on his way to evangelize the Thlinget Indians of Southeastern Alaska. Young is one of Muir's greatest admirers and later writes extensively about him.
