According to National Geographic, a 2009 survey using Light Detection and Ranging (LiDAR) equipment revealed images of an ancient Mayan city stretching over 68 square miles in western Belize. Presented at the recent International Symposium on Archaeometry, in just four days, the airborne lasers showed thousands of structures, 11 roads and thousands of agricultural terraces previously unknown to researchers.
Anthropologists Arlen and Diane Chase, directors of the University of Central Florida Caracol Archaeological Project, have been working in the area for years but have seen only a small fraction of the ruins. The funding for the 2009 LiDAR survey came from NASA, and the survey itself was performed by the National Center for Airborne Laser Mapping.
This survey, along with the recent news that scientists have found more than 200 earthworks in Brazil’s upper Amazon basin with the aid of Google Earth images, lets us see the broad reach of these ancient settlements. Even though they’re far from ready for travelers to see firsthand, it gives us a clearer picture of just how much the natural world can hide the past.
