National Geographic's Quest for the Lost Maya follows a team of archaeologists as they uncover evidence of a forgotten Mayan society in the Yucatán. Buried beneath an ancient pyramid deep in the Yucatán jungle, the team discovers an even more ancient royal palace complex. They unearth a massive stone acropolis that rises nearly 30 feet above the jungle floor and is crowned with a ceremonial platform the size of four football fields; it could have held thousands of people. And, nearly 300 feet underground, they discover cryptic cave paintings that may be among the oldest Mayan iconography ever discovered in Mexico.
