Moray are Incan ruins sit 11,500 feet high in the hills of Peru and form circular grass-covered rings, whose purpose is still unknown by archaeologists. The design and position of the rings to the sun and wind result in various microclimates and a 27 degree Fahrenheit temperature difference between the top and bottom terraces, which along with the built-in irrigation system, hint that the site may have been used for Incan agricultural research.
