The Arkansas River is one of the notable rivers that runs east to west in the United States. It originates in the Rocky Mountains of Colorado and flows southeast before turning eastward through Kansas, Oklahoma, and Arkansas, eventually emptying into the Mississippi River. Another example is the Red River, which forms part of the border between Texas and Oklahoma and also flows east to west.
