PERU Day 11: Mountain biking the Inca wonders of Maras and Moray
The purpose of these depressions to the Incas was a mystery, 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.
