Lidar Reveals 400 Ancient Amazon Geoglyphs, Rewriting Regional History

A lidar survey across ~1,700 square miles of western Brazil’s Amazon uncovered nearly 400 earthworks dating from 600 BCE to AD 850, built by the Aquiry—a large, multicultural group estimated to number up to three million—indicating substantial ceremonial centers and settlements; as many as 20,000 geoglyphs may still lie hidden, with abandonment around AD 850–950 potentially linked to regional collapses seen in other civilizations.

Airborne lasers reveal a vast lost Amazonian civilization of millions

Airborne lidar scans across 1,737 square miles of western Brazil uncovered 400+ earthworks, roads, and geoglyphs linked to the Aquiry culture dating to about 2,500 years ago, implying a connected Amazonian civilization of 1.25–3 million people and a notable ecological footprint from maize and squash farming and forest management; published in Nature, the findings challenge the view of the Amazon as pristine and could reshape climate models, though population estimates are debated and more research is needed.
