A special report by Vega magazine listed the 10 most amazing scientific discoveries, nationally and internationally, for the year 2023. Among them is the discovery of 24 archaeological sites in the Amazon region, some of which are in the state of Akko.
In deforested areas of the western part of the Amazon, it is possible to observe giant geometric shapes on the ground, called geoglyphs, which from the 2000s onwards began to be seen through satellite images, both by scientists and amateurs, using Google Earth. .
In addition to the 24 archaeological sites discovered in Acre, Mato Grosso, Amazonas, Pará and Amapá, while investigating less than 1% of the territory of the Amazon, the study by researchers from the National Institute for Space Research (INPE) estimates that there may still be as many as 23 A thousand pre-Columbian buildings are scattered throughout the area.
The Amazon Basin has been home to various indigenous communities for more than 12 thousand years. These people created structures and occupied areas of the jungle, leaving marks on the current configuration of the Amazon.
Even with all the studies and investigations on this topic, the extent of the impacts these societies have had is little understood. Most of the sites are located in remote locations and hidden under dense forests.
Geography of Akko
