Researchers have discovered over 450 earthworks in the western Brazilian Amazon after flying drones over the area. The large geometrical geoglyphs in Acre, a state in northwestern Brazil within the Amazon rainforest, were built by indigenous people more than 2,000 years ago before the arrival of the Europeans.
Geoglyphs are large designs produced on the ground and are often formed by rocks or similarly durable elements of the landscape such as trees, gravel, earth, and stones.
