They were gone by the time white settlers arrived in 1800.
Nobody knows how or why.
A great spring, Boiling Spring, was here. The site was named after Dr. J. Walter Fewkes of the U.S. Bureau of American Ethnology, who visited the site around 1920 when it was being investigated by William E. Meyer of the bureau. Meyer found five mounds on the 15-acre site. These are called temple mounds because temples were once built atop them. Meyer found circular graves here, more common to gravesites in the Tennessee Valley than in Middle Tennessee.
