Peru's City of Ghosts: Join a team of archaeologists and the Discovery Channel in an investigation into the mysterious lines of the Nazca region in Peru. Created by the Nazcas, these huge sculptures are only visible from the sky and depict people, animal, geometric forms, and strange creatures. See a premier exhibition of pottery and textiles, musical instruments, and mummies from this long-forgotten, pre-Columbian civilization and visit Cahuachi, a buried city of pyramids and ceremonial buildings which may have once been the religious capital of the Nazca people.
