Brazil - Geoglyphs of Acre

The Acre Geoglyphs are earthen excavated structures in the ground and formed by low walls and ditches representing geometrical figures of different shapes. These enclosures were found in the southwestern region of the western Amazon, most predominantly in the eastern portion of the state of Acre, located in areas between streams, creek springs and wetlands, associated mostly with the Acre and Iquiri rivers. Currently in the state of Acre, 306 geoglyphs type archaeological sites have been identified that are made up of 410 earthen structures. However, with the development of archaeological research in the state, the growing number of localized sites is steeply increasing.
