The Aquiry civilization was a civilization located in Southwest Amazonia, in the region of the Acre River. It built extensive networks of roads and geometrical earthworks.
In 2024, satellite imagery of recently deforested areas was used to map a network of earthworks, suggesting wide-scale and ancient human activity in the region. The study also suggested that investigating adjacent forested areas could lead to major discoveries.
A several years-long project involving many flyovers equipped with canopy-penetrating Lidar led to a major revision of the scale and potential influence of this civilization.
