The Mississippi River is the largest river in the United States. With its tributaries, the Missouri and Jefferson rivers, it forms the longest river in North America, and at 2,341 miles in length, the third longest in the world after the Amazon and the Nile.
Author Mark Twain, who had briefly worked aboard a steamboat prior to the Civil War, is heavily associated with the Mississippi River. In particular, his novel Huckleberry Finn which is one of the most famous of all American books, is largely set on the Mississippi River and its surrounding area.
