The first lidar study of the 100-kilometer stone highway that connected the ancient cities of Cobá and Yaxuná on the Yucatan Peninsula 13 centuries ago may shed light on the intentions of Lady K'awiil Ajaw, the warrior queen who an anthropologist believes commissioned its construction at the turn of the 7th century.

The lidar study, which Ardren and fellow researchers with the Proyecto de Interaccion del Centro de Yucatan (PIPCY) conducted in 2014 and 2017 of Sacbe 1 -- or White Road 1, as the white plaster-coated thoroughfare was called -- may shed light on the intentions of Lady K'awiil Ajaw, the warrior queen who Ardren believes commissioned its construction at the turn of the 7th century.

In an analysis of the lidar study, recently published in the Journal of Archaeological Science, the researchers identified more than 8,000 tree-shrouded structures of varying sizes along the sacbe -- with enough total volume to fill approximately 2,900 Olympic swimming pools. The study also confirmed that the road, which measures about 26 feet across, is not a straight line, as has been assumed since Carnegie Institute of Washington archaeologists mapped its entire length in the 1930s, with little more than a measuring tape and a compass.

Rather, the elevated road veered to incorporate preexisting towns and cities between Cobá, which known for its carved monuments depicting bellicose rulers standing over bound captives, controlled the eastern Yucatan, and Yaxuná -- a smaller, older, city in the middle of the peninsula. Yet, the isolated Yaxuná (pronounced Ya-shoo-na) still managed to build a pyramid nearly three times bigger and centuries before Chichén Itzá's more famous Castillo, about 15 miles away.
