Stretching along the horizon south of Fort Smith, the rocky ridge provided a natural barrier dividing the Arkansas River valley from the Ouachitas region to the south. While portions of the 10-acre Devil's Backbone Battlefield have suffered from development, most of the historic landscape retains its 1863 integrity.  Some of the Confederate defensive works still exist. A monument commemorating the battle is located on the northern slope of Devil’s Backbone adjacent to U. S. Route 71 just southwest of the town of Greenwood, Arkansas.
