As you stand on a hill in the town of Maras in Peru, you can’t stop but notice steps that are carved out of a hillside in the shape of square ponds. In this small village town of Maras, salt is harvested at 9000 feet above sea level even though the nearest ocean is thousands of miles away. The saltwater ponds in Maras show that humans know how to adapt, survive and use natural resources around them in most productive ways.
