A high-resolution LiDAR survey conducted over the Mirador-Calakmul Karst Basin has revealed a previously unknown fortified Maya settlement dedicated exclusively to the production and defense of salt. Unlike typical urban centers, this site features a massive perimeter wall and specialized elevated brine-boiling platforms designed to protect valuable salt cakes from both seasonal flooding and rival city-state raids during the Late Classic period.
The mapping identifies a 50-mile network of paved causeways connecting this 'Salt Fortress' to major inland Maya cities, highlighting the critical role of salt as a strategic commodity for food preservation. Archaeological ground-truthing confirmed the presence of thousands of ceramic brine-boiling vessels and a centralized administrative plaza where salt shipments were likely weighed and taxed. This discovery redefines our understanding of Maya economic warfare and the militarization of essential resources.
