This river that empties into the Gulf of Mexico divides the United States roughly in half vertically. What is the name of this river whose source is Lake Itasca in northern Minnesota?

With a length of 2,340 miles (3,766 km) the Mississippi River ranks as the 20th longest river in the world. However when combined with the Missouri-Jefferson (Red Rock) water systems that feed into the Mississippi, it counts as the 4th longest river in the world.
