There are three major rivers to the Western Hemisphere and they are Yukon, Copper and Mackenzie river. :)
The Missouri River starts in Montana and flows generally east and south for 2540 miles before flowing into the Mississippi River, the second longest river in the United States. The Mississippi River (the largest river system) flows from Minnesota to the Gulf of Mexico. The Missouri and the lower Mississippi are usually considered as a single waterway, which is among the longest in the world.
