Long-hidden ruins of vast network of Maya cities could recast history
by Charlotte Lytton
Beneath 1,350 square miles of dense jungle in northern Guatemala, scientists have discovered 417 cities that date back to circa 1000 B.C. and that are connected by nearly 110 miles of “superhighways” — a network of what researchers called “the first freeway system in the world.”
Scientist say this extensive road-and-city network, along with sophisticated ceremonial complexes, hydraulic systems and agricultural infrastructure, suggests that the ancient Maya civilization, which stretched through what is now Central America, was far more advanced than previously thought.
Mapping the area since 2015 using lidar technology — an advanced type of radar that reveals things hidden by dense vegetation and the tree canopy — researchers have found what they say is evidence of a well-organized economic, political and social system operating some two millennia ago.
The discovery is sparking a rethinking of the accepted idea that the people of the mid- to late-Preclassic Maya civilization (1000 B.C. to A.D. 250) would have been only hunter-gatherers, “roving bands of nomads, planting corn,” says Richard Hansen, the lead author of a study about the finding that was published in January and an affiliate research professor of archaeology at the University of Idaho.
