Archaeologists have rediscovered an ancient Indigenous society in western Ecuador's Upano Valley, featuring more than 6,000 earthen platforms that once supported houses and communal buildings in 15 urban centers.
The unique brand of garden urbanism found in Upano Valley has not been seen anywhere else in the ancient Americas and is the oldest civilization uncovered in the area.
The infrastructure in Upano Valley is completely unprecedented in Amazonia and in Andean prehistory.
