This new book focuses on the Urubamba Valley of Peru, which spans 4000 meters of altitude mostly in the Department of Cusco. More than one million visitors a year come to the Urubamba, especially to experience Machu Picchu, which overlooks the valley floor. The book, based on over 50 years of research and field work, represents an impressive accumulation of regional knowledge and testifies to how a long scholarly commitment can lead to a deep understanding of place, that probes the present and past, human and non-human, common and uncommon.
