Nearly 1,000 Maya sites have been discovered in the Mirador-Calakmul Karst Basin (MCKB) of northern Guatemala thanks to a new LIDAR survey. The finds are more than 2,000 years old and include pyramids, platforms, ballcourts, reservoirs, and 110 miles of raised roads. According to the study, “The LiDAR survey revealed an extraordinary density and distribution of Maya sites concentrated in the MCKB, many of them linked directly or indirectly by a vast causeway network.”
