Topics citing it and claims using it

Topic citing this source

Amazon Earthworks, Geoglyphs, and Water Systems

Open topic
Supporting citation for public claim

Field-validated earthworks, geoglyph landscapes, and lidar-mapped causeways, canals, and reservoirs in studied Amazonian regions document substantial precolonial Indigenous landscape engineering.

The features are physically measurable and often confirmed by multiple archaeological methods.
Open claim topic
Supporting citation for public claim

AT-1042 reports lidar and model-based evidence for more than 20,000 precolonial earthworks in southwestern Amazonia, but its regional estimates do not establish 20,000 ground-verified sites or a pan-Amazonian polity.

The dossier treats this as an open source and evidence question.
