Salinas de Maras en el Valle Sagrado cerca de Cuzco. Maras is a town in the Sacred Valley of the Incas, 40 kilometers north of Cuzco, in the Cuzco Region of Peru. The town is well known for its nearby salt evaporation ponds, in use since Inca times. The salt-evaporation ponds are up-slope, less than a kilometer west of the town. The Maras area is accessible only by a poorly maintained dirt road, which leads from the main road leading through the Sacred Valley between Cuzco and the surrounding towns. Tourist sites in the area include the colonial church, the local salt evaporation ponds, and the surrounding scenery. Since pre-Inca times, salt has been obtained in Maras by evaporating salty water from a local subterranean stream. The highly salty water emerges at a spring, a natural outlet of the underground stream. The flow is directed into an intricate system of tiny channels constructed so that the water runs gradually down onto the several hundred ancient terraced ponds. Almost all the ponds are less than four meters square in area, and none exceeds thirty centimeters in depth. All are necessarily shaped into polygons with the flow of water carefully controlled and monitored by the workers. The altitude of the ponds slowly decreases, so that the water may flow through the myriad branches of the water-supply channels and be introduced slowly through a notch in one sidewall of each pond. The proper maintenance of the adjacent feeder channel, the side walls and the water-entry notch, the pond's bottom surface, the quantity of water, and the removal of accumulated salt deposits requires close cooperation among the community of users. It is agreed among local residents and pond workers that the cooperative system was established during the time of the Incas, if not earlier. As water evaporates from the sun-warmed ponds, the water becomes supersaturated and salt precipitates as various size crystals onto the inner surfaces of a pond's earthen walls and on the pond's ear
