Flooding threatens ancient Native cave art in Tennessee

Flooding at Dunbar Cave State Park in Tennessee has raised concerns over potential damage to 800-year-old Mississippian charcoal drawings, according to park officials. Heavy rains submerged the artwork for the first time, leaving a layer of mud that could cause permanent harm. Rangers are working with archaeologists to assess the impact and explore why flooding has worsened. Dunbar Cave houses the only publicly accessible dark-zone cave art in the U.S.
