Scientists using laser LiDAR (Light Detection and Ranging) technology have discovered the Kotoka settlement of the Kasarabe culture, which existed from 500 to 1400 AD, in the Amazon within Bolivia. This method ‘removes’ from the image the ground that actually exists and reveals what lies beneath it.
Archaeologists knew about this civilization but were unable to locate its location until recently.
26 settlements connected by roads were discovered. It appears to have been an urban and suburban network of 7.5 square kilometers. Architectural landmarks of a religious nature were discovered, such as pyramids 25 meters high. There was still an irrigation system with canals and artificial reservoirs.
