|SATURDAY, JANUARY 13, 2007. CHINCHERO, MORAY, AND SALINAS, PERU. Omer, the Israeli Geography professor, invited me and a couple of Argentinean chicas (Hichi and Cecilia) from his hostel for a tour of sights in Cuzco's Sacred Valley. Our first stop was Chincero, with its church and nearby Inca ruins. From Chincero, we visited Moray, where the Incas built terracing in an amphitheater-like shape. At each level, the temperature varied slightly, permitting the Incas to grow different crops. We ended the day at the Salinas, hundreds of salt pools fed by a single salt spring. The Incas extracted salt by letting the salt pools dry.
