Network of Cities and Towns Revealed by Lidar
I love how much there is to still learn about past civilizations and how much there is more to discover.
An airborne lidar survey recently revealed the long-hidden ruins of 11 pre-Columbian Indigenous towns in what is now northern Bolivia. The survey also revealed previously unseen details of defensive walls and complex ceremonial buildings at 17 other settlements in the area, built by a culture about which archaeologists still know very little: the Casarabe.
