Five hundred years ago the Inca Empire stretched across the Andes Mountains of South America, encompassing arid coastal deserts, snow-covered mountains, and humid rainforests.... Since the empire fell in the 16th century, there is something that no subsequent government ruling over this territory has successfully achieved.
High in the Andes Mountains, the archaeological site of Moray holds many mysteries. Starting with natural sinkholes, Inca builders lined a set of huge circular depressions with concentric terraces. Constructing Moray required tremendous engineering skill and thousands of hours of construction efforts, so why was it built?
The Incas were accomplished engineers who built long-lasting structures, from Machu Pichu on a ridgetop to the Inca Road system along the spine of the Andes Mountains. A sculpted landscape masterpiece that is less well known is a set of large circular depressions lined with concentric rings of stone-lined terraces. Named Moray and located on a high plain about 20 miles northwest of Cusco, these circles began as deep natural sinkholes with unstable slopes at the angle of repose.
Small salt ponds numbering in the thousands are arranged on steep mountain slopes near the city of Cusco, former capital of the Inca Empire, high in the Andes Mountains of Peru. Known as Maras, and originating from a saline spring, these salt ponds have been tended carefully since Inca times 500 years ago, and possibly for hundreds (or thousands?) of years before the Incas.
