"Nobody who seeks a deeper understanding of Yellowstone's natural systems as they were in 1871, or how nineteenth-century science was yoked to westward expansion, should miss this remarkable piece of editing and scholarly reconstruction." Nature "Well conceived, beautifully produced... This volume belongs on the shelf of everyone interested in Yellowstone National Park or in the larger story of how the geological surveys mixed science, government, and the lure of adventure to create a vision of the West that endures today." Annals of Wyoming
