where does the arkansas river join the mississippi river
Arkansas River Into western Arkansas, the river path works between the encroaching Boston and Ouachita Mountains, including many isolated, flat-topped mesas, buttes, or monadnocks such as Mount Nebo, Petit Jean Mountain, and Mount Magazine, the highest point in the state. The river valley then expands as it encounters much flatter land beginning just west of Little Rock, Arkansas. It continues eastward across the plains and forests of eastern Arkansas until it flows into the Mississippi River.
