Harvesting salt 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 these several hundred ancient terraced ponds. . . #amateurs_bnw #awesomebnw #bnw_rose #bnwsouls #blackandwhite #bnw_captures #bnw #bnw_madrid #top_bnw #bw_perfect #ig_worldbnw #bw_awards #bnw_planet #bnw_just #bnw_life_shots #bnw_life #ig_shotz_bnw #globeshotz #bnwmood #masters_in_bnw #likeforlike #like4like #natgeo #igersperu #natgeotravel #bnw_lombardia #salt #peru #ExperiencePeru #igerscusco (at Maras, Peru)
