MARAS SALT MINES AND MORAY INCA AGRICULTURAL STATION
One of the most remarkable feature of the site is the vast difference in temperature that exist between the top and the bottom reaches of the structure, which can be as much as 15°C (27°F). This large temperature difference creates micro climates, similar to what is achieved in greenhouses in modern times, that was possibly used by the Incas as an agricultural laboratory to study the effects of different climatic conditions on crops.
