Arkansas is a state located in the southern region of the United
States. Its name is an Algonquian name of the Quapaw Indians.
Arkansas shares borders with six states (clockwise: N:Missouri;
E: Tennessee, Mississippi; S: Louisiana; SW: Texas; W:
Oklahoma), and its eastern border is largely defined by the
Mississippi River. Its diverse geography ranges from the
mountainous regions of the Ozarks and the Ouachita Mountains,
which make up the U.S. Interior Highlands, to the eastern
lowlands along the Mississippi River. The capital and most
populous city is Little Rock, located in the central portion of
the state.
