Sebastian County

Sebastian County is located on Arkansas’s western border in the natural division known as the Arkansas Valley. The Arkansas River forms the county’s northern border, while its southern border touches upon the Ouachita Mountains. The county is home to Fort Smith, one of the state’s largest cities, as well as Fort Chaffee, and in the late nineteenth and early twentieth centuries, it was the site of the state’s largest coal-mining operations. From the earliest days of the territorial period to the present, Sebastian County has served as a major transportation corridor to points west.
