Designs upon Nature traces how and why the cultural landscapes-the built environment-of America's first national park have evolved since its creation in 1872.  Yellowstone National Park will always be defined by its geysers, wild animals, and natural setting, yet visitor experiences in the park are also shaped by the lodges, campgrounds, museums, ranger talks, boardwalks, roads, trails, and viewpoints they encounter.  These richly illustrated essays explore the evolution of these cultural features amid this unique natural landscape and explain how they have served ever-changing visitor needs over the past 150 years.
