Ghosts of Machu Piccu - Nova (0:52) 2010

Ghosts of Machu Piccu is a Nova: National  Geographic Special that examines the reason(s) why and how the Incas built Machu Piccu. The Incas didn't have a written language nor did they leave art work so Machu Piccu is a huge puzzle. The stone buildings were built without the use of the wheel, the brick work was so precise that mortar was not needed. Besides being builders, the Incas had an elaborate aqueduct system for water delivery and had many terraces used in food production. Yet, the Incas at Machu Piccu lasted for about a hundred years. The next puzzle is uncovering the reasons for their demise. Nova with National Geographic did a marvelous job filming Macchu Piccu and its surroundings. There are explanations for some of the puzzles but the jigsaw puzzle is not completely assembled. This is a very interesting documentary. This would be a good video for any Middle or High School student who is working on an Incan project.
