Arkansas is a state of the south-central United States bordered on the east by the Mississippi River. Arkansas is the first state in the U.S. where diamonds were found naturally. Its approximated population is 2,720,000. Nearly all of the rivers flow from northwest to southeast and empty via the Arkansas and the Red into the Mississippi, which forms the major eastern boundary.
Arkansas is surrounded Missouri to the north, Tennessee and Mississippi to the east, Louisiana to the south, Texas to the southwest, and Oklahoma to the west. Arkansas has the high Ozark and Ouachita mountains in the north and west and a heavy tracery of rivers that cut through its rich agricultural lands. Little Rock is the capital and the largest city.
