What comprises the "Mississippi Delta" and why is it called that?

Answer 1

Mississippi Delta (disambiguation).

The shared flood plain of the Yazoo and Mississippi RiversThe Mississippi Delta is the distinct northwest section of the state of Mississippi that lies between the Mississippi and Yazoo Rivers. Technically not a delta but part of an alluvial plain, it has been said that The Delta "begins in the lobby of the Peabody Hotel (in Memphis) and ends on Catfish Row in Vicksburg" (various writers have been attributed with composing this memorable line, but most often David Cohn is credited with the saying). This region, created by regular flooding over thousands of years, is remarkably flat and contains some of the most fertile soil in the world. It includes Washington, Humphreys, Carroll, Issaquena, Quitman, Bolivar, Coahoma, Leflore, Sunflower, Sharkey, Tunica, Tallahatchie, Holmes, and Yazoo counties.
