14th Century Amazon Inland Sites Discovered
Archaeologists are discovering that Pre-Columbian settlements in the Amazon of Brazil exist in areas not near rivers. 110 settlements in an inland region of the Amazon have been researched for 10 years. Water storage depressions and ponds enclosed by berms of clay and middens have been found at these sites. There was a 14th century inland expansion as water management and agriculture developed in the Amazon, accompanied by population growth. River banks are flooded during the 6 month rainy season, so the inland areas were farmed during the wet season.
