Thanks decimon.
...housing a society doomed by the arrival of Europeans five centuries ago... The existence of the ancient settlements in the Upper Xingu region of the Amazon in north-central Brazil means what many experts had considered virgin tropical forests were in fact heavily affected by past human activity, the scientists said.
They had to get that shot in about how evil Euros destroyed an indigenous culture that there was no sign anyone outside the Amazon has ever heard of before, prior to getting down to the buried lead, which is that there isn't a pristine piece of land anywhere. :')

Prehispanic Raised Field Agriculture: Applied Archaeology in the Bolivian Amazon

Until about 30 years ago, Western academic opinion agreed that the Amazon Basin could never have sustained large populations; due to the limitations of a tropical environment, the area could support only hunting and gathering and slash-and-burn agriculture. Subsequent archaeological research proved this opinion wrong. The savannas and forest of the Bolivian Amazon were, in fact, once densely populated by well-organized societies, and precolumbian farmers heavily modified the landscape.

Prehispanic raised fields in the savannas of the Llanos de Moxos of Bolivia. The elevated planting platforms are 20 meters wide, 0.2-1 meter tall, and up to 600 meters long.
