Moray is
an archaeological site in Peru approximately 50 km (31 mi)
northwest of Cuzco on a high plateau at about 3500 m (11,500 ft)
and just west of the village of Maras. The site contains unusual
Inca ruins, mostly consisting of several enormous terraced circular
depressions, the largest of which is about 30 m (98 ft) deep.
The
purpose of these depressions is uncertain, but their depth and orientation with
respect to wind and sun creates a temperature difference of as much as 15 °C
(27 °F) between the top and bottom. This large temperature difference was
possibly used by the Inca to study the effects of different climatic conditions
on crops. In other words, Moray was perhaps an Inca agricultural experiment
station. As with many other Inca sites,it also has a sophisticated irrigation
system.
