Machu Picchu, in the valley of the Urubamba, north of Cuzco. These ruins of an ancient Inca city were discovered by Hiram Bingham, of the Yale University and National Geographical Society expedition, in 1911, and are by him identified with the "Tampu-Tocco" of Inca tradition (see pages 216-18, and Plate XXXVIII).
