Researchers at the University of Colorado at Boulder (CU-Boulder) and at NASA have used satellites to track the movements of people living in the Arenal region of Costa Rica more than 2,000 years ago. They've also used video-game software to virtually 'fly' above the footpaths taken by Central Americans between small villages and cemeteries. It's a fascinating story because Arenal Volcano is still very active and that the people who lived there didn't disappear as highly structured societies like the Maya and Aztec. And people living today in the Arenal region are certainly friendlier than your neighbors.
This research has been led by CU-Boulder Professor Payson Sheets, of the Center to Advance Research and Teaching in the Social Sciences (CARTSS) and who's focused on "Investigating The Origins of Monumentality in Ancient Costa Rica."
