Around the campfire in September 1870, a small group of men who had just spent more than a month wandering in what they called "Wonderland" came up with a grand idea: to protect the incredible landscape for all to enjoy by designating it a national park. And in 1874, Yellowstone National Park was born. In this unique book, a contemporary landscape photographer's color images accompany excerpts from the journal of that famous trek, published as The Discovery of Yellowstone Park by expedition member Nathaniel P. Langford. Text and photographs combine to give readers the same experience of discovery that those nineteenth-century explorers enjoyed.
