Arkansas River Frontier — Spiro Mounds, Fort Smith & the Hanging Judge
Along the far eastern edge of Oklahoma, where the Arkansas River carves the boundary with Arkansas, three days of travel span more than a thousand years of frontier history. Day one journeys east to the Spiro Mounds Archaeological Center, the only prehistoric Native American archaeological site in Oklahoma open to the public and once among the most important ceremonial cities of the Mississippian world. Day two crosses the river to Fort Smith, Arkansas, and its National Historic Site — Judge Isaac Parker's federal courtroom, the reconstructed gallows of the 'Hanging Judge,' and the museums that tell the story of the wild border of Indian Territory. Day three explores Fort Smith's Belle Grove Historic District and rides the vintage trolley in neighboring Van Buren before the drive home. Two nights in Fort Smith anchor the journey.
