Tombigbee National Forest in eastern and northeastern Mississippi, named for the nearby Tombigbee River, spans 67,005 acres in two separate sections rather than one continuous tract. The larger southern section lies north of Louisville in parts of Winston, Choctaw, and Oktibbeha counties, while the smaller northern section lies northeast of Houston in parts of Chickasaw and Pontotoc counties. Administered from Jackson with local offices in Ackerman, the forest is especially notable for the Owl Creek Mounds, five platform mounds built between 1100 and 1200 CE, which preserve an older human presence within this protected woodland.
