The Bat Creek inscription (also called the Bat Creek stone or Bat Creek tablet) is an inscribed stone collected as part of a Native American burial mound excavation in Loudon County, Tennessee, in 1889 by the Smithsonian Bureau of Ethnology's Mound Survey, directed by entomologist Cyrus Thomas. The inscriptions were initially described as Cherokee, but in 2004, similarities to an inscription that was circulating in a Freemason book were discovered. Hoax expert Kenneth Feder says the peer reviewed work of Mary L. Kwas and Robert Mainfort has "demolished" any claims of the stone's authenticity. Mainfort and Kwas themselves state "The Bat Creek stone is a fraud."
