This picture is taken in Cusco, Peru. Moray Quechua: Muray is an archaeological site in Peru approximately 50 kilometres northwest of Cuzco on a high plateau at about 3,500 metres and just west of the village of Maras. The site contains unusual Inca ruins, mostly consisting of several terraced circular depressions, the largest of which is approximately 30 m deep. As with many other Inca sites, it also has an irrigation system. The purpose of these depressions is uncertain, but their depth, design, and orientation with respect to wind and sun creates a temperature difference of as much as 15 ðC between the top and the bottom. It is possible that this large temperature difference was used by the Inca to study the effects of different climatic conditions on crops. Speculation about the site has led to discussion about Moray as an Inca agricultural experiment station.[citation needed] Its microclimatic conditions and other significant characteristics led to the use of the site as a center for the ancient study of domestication, acclimatization, and hybridization of wild vegetable species that were modified or adapted for human consumption.
