Exploration and Empire: The Explorer and the Scientist in the Winning of the American West

William H. Goetzmann follows the explorers, surveyors and government scientists who mapped the American West across the nineteenth century, arguing that their work was never simply discovery for its own sake. Goetzmann traces expeditions from the fur trapping mountain men and army topographical engineers of the early republic through the great postwar surveys, the geologists, botanists and cartographers who accompanied railroad routes and government expeditions as the country pushed toward the Pacific, showing how each expedition served scientific curiosity and national ambition at the same time.

Goetzmann reads exploration as an instrument of empire as much as of knowledge, following how the data explorers gathered, about terrain, resources and Native peoples, fed directly into decisions about railroads, settlement and military strategy that extended American control over the West. He gives close attention to the professionalization of exploration itself, as amateur adventurers gave way across the century to trained scientists working within organized federal surveys, a shift that turned the West from a frontier explored by individuals into a landscape mapped and interpreted by an emerging scientific establishment working in the government's service.

Goetzmann writes with an eye for both the individual explorers and the institutions that sent them, and reading the book means following exploration as a genuinely interdisciplinary story, part science, part military strategy, part national mythmaking, told across the length of a century. It suits a reader who wants the settlement of the West explained through the surveys and expeditions that made it possible rather than through the more familiar cast of pioneers and cavalry.
