Salt: Mover and shaker in ancient Maya society

Salt is essential for life. As ancient civilizations evolved from hunters and gatherers to agrarian societies, it has not been clear how people acquired this mineral that is a biological necessity. However, an anthropologist at LSU discovered remnants of an ancient salt works in Belize that provide clues on how the ancient Maya at the peak of their civilization more than 1,000 years ago produced, stored and traded this valuable mineral. New analyses of stone tools found at this site, called the Paynes Creek Salt Works, reveal that not only were the Maya making salt in large quantities, but they were salting fish and meat to meet dietary needs and producing a commodity that could be stored and traded.
