Zona Arqueologica Moray

This guide to the Zona Arqueologica Moray, near Cusco, questions the tidy story every tour script repeats about these nested green terraces: that the Inca built them as a crop laboratory, each ring a degree warmer than the last. It follows the physicist who proposed that theory in 1975, and the later hydrological survey and researchers, including his own research partner, who could not make the numbers or the water supply add up. You will hear why the coldest terraces sitting at the bottom breaks the theory entirely. If not Inca scientists, the question left standing at the rim is who actually put these rings to use, and why.
