Moray
Moray is an archeological site approximately halfway between Cuzco and Machu Picchu. The site is noted for its three unusual depressions of concentric terraced circles. Vertical channels drop water from one level of the terrace to the next, creating a beautiful waterfall-like effect. Unlike Machu Picchu, Moray did not receive enough rain to sustain agriculture. Therefore, aqueducts were required for transporting water from the three surrounding springs. Reservoirs supplemented those aqueducts, which allowed for a steady flow of water despite the variable yields of the springs.
