Artist Ed Martin's depiction of salt-making scene based on historic accounts and archeological evidence from the Ouachita Valley in Arkansas. Caddo groups who lived near natural seeps of highly salty water called salines collected the salt by evaporating the water. In 1700, French explorers encountered Ouachita Caddos paddling canoes laden with salt on the lower Red River on their way to trade with the Taensa people living in the lower Mississppi Valley.
