Ozark Mountains Arkansas Valley Ouachita Mountains Gulf Coastal Plain Delta Crowley's Ridge Click arrow to choose A land of rivers, the Delta covers the eastern third of Arkansas. Major cities include Helena, Blytheville, West Memphis, Brinkley, Clarendon, Stuttgart and Lake Village. When the Gulf of Mexico receded from the Delta millions of years ago its geological deposits were removed by rivers and replaced by deep layers of sand, silt and clay.
Flat bottomlands characterize the area and today, it is a major agricultural region.
Powerful rivers, the Arkansas, White and Mississippi, flow through the area and often cause floods. Natural vegetation includes cypress and tupelo trees that live in lakes and swamps that are permanently flooded. Oaks, hickory and pecan trees grow well in the Delta. The pecan trees are often grown in orchards and provide a marketable good. For this reason, Arkansas is considered a favorite place to hunt ducks during season.
