A passionate series of descriptive sketches and essays that celebrate mountain parks and forest reservations, surveying landscapes, forests, sequoias, waterways, animals, and birds while profiling major sites such as Yellowstone, Yosemite, and Sequoia. The writing blends vivid natural history and personal observation with reflections on the restorative value of wildness and arguments for preservation and sensible management. Practical material such as maps and tables supplements lyrical passages, and the work emphasizes the parks' combined utilitarian roles in providing water and timber and their spiritual and recreational importance, urging readers to experience, value, and protect these wild places.
