Charles C. Mann Quote
Most of the salt occurred in the sediments on the swamp bottoms. To make the water potable, the Maya laid a layer of crushed limestone atop the sediments, effectively paving over the salt. As the researchers noted, the work had to be done before the Maya could move in and set up their milpas and gardens.
