Archaeologists have used laser expertise to map a 100-km (62-mile) Maya stone highway that would have been constructed 1,300 years in the past to assist with the invasion of an remoted metropolis in modern-day Mexico. The traditional freeway is assumed to have been constructed on the command of the warrior queen Woman Ok’awiil Ajaw, and would have been coated in white plaster.
The 26 ft (eight m)-wide highway, also referred to as Sacbe 1 or White Highway 1, stretches from the traditional metropolis of Cobá – one of many best cities of the Maya world – to the distant, smaller settlement of Yaxuná, situated within the Yucatan Peninsula.
Newly-published analysis has shed new gentle on the character of Woman Ok’awiil Ajaw’s nice highway by making use of sunshine detection and ranging, in any other case often called LiDAR expertise. To take their measurements, the authors made use of an airborne LiDAR instrument, which beamed lasers on the floor because it handed over the traditional highway.
These lasers hit the bottom and bounced again to the instrument, which recorded the elapsed time between emitting the sunshine and detecting its return. By analyzing this information, the scientists had been capable of make detailed 3D maps of areas which can be ordinarily shrouded by impenetrable jungle.
The LiDAR scans uncovered eight,130 buildings clustered alongside the traditional highway. Within the paper, it’s estimated that their mixed quantity would fill 2,900 Olympic-sized swimming swimming pools.

As an alternative of working straight, as was beforehand regarded as the case primarily based on measurements taken within the 1930s, the LiDAR information additionally revealed that the huge highway curved round a lot of cities and cities on the way in which to its remaining vacation spot. This implies that the highway would possible have shaped an arterial freeway, connecting the 1000’s of individuals dwelling within the area.
The authors of the research hypothesize that the highway may have been constructed by Woman Ok’awiil Ajaw to pave the way in which for territorial growth, as a way to reply the risk from the encroaching Chichén Itzá empire. Cobá might have been seeking to occupy the remoted metropolis of Yaxuná within the heart of the peninsula, as a way to achieve a foothold in opposition to the rising risk.
“It was constructed simply earlier than 700, on the finish of the Basic Interval, when Cobá is making a giant push to broaden,” stated Traci Ardren, an archaeologist and professor of anthropology on the College of Miami, and co-author of the brand new research. “It’s attempting to carry on to its energy, so with the rise of Chichén Itzá, it wanted a stronghold within the heart of the peninsula. The highway is likely one of the last-gasp efforts of Cobá to take care of its energy.”
As a part of the research, the crew excavated clusters of buildings situated alongside the boundary of the cities of Cobá and Yaxuná, and are planning a 3rd dig within the coming summer season. Their aim is to determine a similarity in the kind of family items used all through the 2 distant inhabitants facilities.
The paper has been printed within the Journal of Archaeological Science.
