MARAS SALT MINES AND MORAY INCA AGRICULTURAL STATION
Pre-Inca Maras salt mines and Moray’s Inca agricultural station are two fascinating tourism wonders of Peru located very close from each other approximately 50 km northwest of Cuzco in the Urubamba valley
It is no coincidence that the temperature difference corresponds to the natural difference between coastal sea level farmland and Andean farming terraces 1,000 meters above sea level. Furthermore, pollen studies indicate that soils from different regions of the Inca Empire were imported to each of the large circular terraces.
Another enigma is the way how drainage for water flowing through the aqueducts worked. The lowest level is perfectly drained and never gets flooded even after incessant rains. It is suggested that there must be underground channels built by the depressions' bottom allowing water to drain. It is also argued that the bottom is over a very porous natural rock formation that enables water filtering towards the earth's interior.
