New York Times: A husband-and-wife archaeological team from the University of Central Florida in Orlando have used a new approachâmdash;lidar (light detection and ranging)âmdash;to investigate the remains of one of the largest Maya cities in Central America. By using airborne laser signals that penetrated the dense jungle in Belize, Arlen and Diane Chase mapped out the topographic detail of the site of ancient Caracol—an area that the couple has been studying for the past 25 years.
