The Upano valley, located at the foot of the Andes in Ecuador’s eastern part, has been the site of significant archaeological discoveries. In 2015, a study was conducted that revealed the extent of these ruins. The findings are comparable to those of more famous Mayan cities in Central America and point to the existence of large, open-plan “garden cities,” with tens of thousands of people living in them.
However, unlike what was previously believed, these ruins were not built by small tribes of hunter-gatherers. Recent discoveries suggest that up to eight million people lived in the Amazon rainforest before the arrival of Europeans. Despite this, the objects found in the Upano valley have been dated back more than 1,500 years, indicating that they were abandoned before Europeans arrived. Possible reasons for this include volcanic eruptions as deposits of volcanic ash were found in the area.
While these discoveries provide valuable insights into human history in South America, there are also articles about what house buyers look for and why buyers pull out of house sales. These articles provide information on selling houses to cash buyers, house buyer surveys and whether or not house buyers pay commission.
