This work examines the valley of the Urubamba River in terms of vertical zonation, Incan impact on the environment, plant use, the history of exploration and the notion of discovery, the idea of land reform, and cultural contact with the European world. Winding its path northward from the Andean Highlands to the Amazon, the valley has served as the stage of pre-Columbian civilizations and focal point of Spanish conquest in Peru. "Gade left behind not only a superb body of scholarly work, but a network of colleagues and students who remain indebted to his example. This book should serve as an inspiration for all scholars who wish to pursue the Sauerian, counter enlightenment or post development agendas of understanding and respecting particular places in all their historical and cultural complexity, including ambiguities and contradictions." -- The Geographical Review, American Geographical Society
