A provocative new way to read and interpret the classic works of John Muir, Mary Austin, and Gary Snyder, and to bring their ideas into the discussion of ecological values and the current environmental crisis. Lewis combines a perceptive discussion of their work and ideas with an engaging account of his own trail experiences as hiker/backpacker and volunteer trail builder, proposing that such a field-based, interdisciplinary approach to literary study and outdoors experience can enrich our appreciation for the work of nature writers.
