Washita Battlefield National Historic Site protects and interprets the site of the Southern Cheyenne village of Peace Chief Black Kettle that was attacked by the 7th U.S. Cavalry under Lt. Col. George A. Custer just before dawn on November 27, 1868. The controversial strike was hailed at the time by the military and many civilians as a significant victory aimed at reducing Indian raids on frontier settlements. Washita remains controversial because many Indians and whites labeled Custer's attack a massacre. Black Kettle is still honored as a prominent leader who never ceased striving for peace even though it cost him his life.

The “Peaceful Valley of Rippling Waters” appropriately describes Chickasaw National Recreation Area, as it is known for its many mineral springs, cool water, flora, fauna, and wildlife. Here one’s mind may wander back in time to when the early American Indian came to this area to rest, relax at the water’s edge, and hunt for their food from the abundant wildlife. This area has significant geological and hydrological features and lies in the transitional ecotones of the Eastern deciduous forest and the Western prairies.

At Fort Smith National Historic Site you can walk where soldiers drilled, pause along the Trail of Tears, and stand where justice was served. The park includes the remains of two frontier forts and the Federal Court for the Western District of Arkansas. Exhibits in the visitor center focus on Fort Smith’s military history from 1817 – 1871, western expansion, Judge Isaac C. Parker and the federal court’s impact on Indian Territory, U.S. Deputy Marshals and outlaws, Federal Indian policy, and Indian Removal including the Trail of Tears. Located on the grounds are the foundation remains of the first Fort Smith (1817-1824), the Commissary building (c. 1838) and a reconstruction of the gallows used by the federal court. A walking trail along the Arkansas River includes wayside exhibits on the Trail of Tears.

The Trail of Tears National Historic Trail commemorates the removal of the Cherokee and the paths that 17 Cherokee detachments followed westward. Today the trail encompasses about 2,200 miles of land and water routes, and traverses portions of nine states.
