NASHVILLE, TENNESSEE—A prehistoric site consisting of fire pits and ceramics has been uncovered at a construction site in Nashville. State archaeologist Mike Moore thinks the site had been a workshop where mineral water was boiled to collect salt as early as 1150 A.D. “This is one of those few chances we’ve had to actually get real, hard scientific evidence of who was here and what they were doing,” archaeologist Kevin E. Smith of Middle Tennessee State University told WBIR. A ball park will be built on the site, but the remaining artifacts will be protected.
