Can today's visitor to Yosemite National Park still find what John Muir encountered a century ago? Thomas and Geraldine Vale retrace Muir's path, based upon journals of his first summer in the Sierra Nevada Mountains. Illustrated with drawings by Muir and photographs and drawings by the Vales, Walking with Muir across Yosemite shows that current visitors to Yosemite can still find much of the solitude and wildness Muir experienced. The Vales suggest, however, that a national parks policy promoting nature study could encourage a more profound interaction between humans and the natural world.
