Time Scanners: Machu Picchu

Gr 10 Up—Once again, the series brings laser-mapping technology to an archaeological site—Machu Picchu in Peru—and this time produces an elegant 3-D digital map of the Incan city situated 8,000 feet above sea level. The program connects the Incan people with modern-day Peruvians and attempts to answer key questions regarding the construction of the site. Why was it built in the mountains? Where was the water source? Engineer Steve Burrows provides expert insight into the construction methods employed, examining the terrace system and the building stones. In addition to using the laser scans, archaeologists employ ground-penetrating radar to obtain a subterranean look of the terrace construction. The segment also includes a jungle adventure, the search for high-altitude water sources—viewers will enjoy the beautiful mountain scenery. The focus is on engineering, construction, and hydrology, as opposed to Peruvian culture, society, or indigenous perspectives. Thus, some may find the conclusions to be somewhat environmentally determinist.
