Spell of the Urubamba

the long version

"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."--
