The Mississippi River Alluvial Plain, USA – June 28th, 200934.0N 91.1W
The Mississippi River snakes its way vertically across this image, appearing tan from sediments and, to the south, white from sun glint.
The land around it is tan in color, whereas the rest of the terrain in the image is dark green. This tan area is the Mississippi River Alluvial Plain, an alluvial plain created by the river.
The plain includes parts of seven states, from southern Louisiana (below) to southern Illinois (above).
It is divided into the Mississippi River Delta in the southern half of Louisiana and the inland Mississippi Embayment running from central Louisiana to Illinois.
It is the largest ecoregion of Louisiana, covering 12,350 square miles, and including all of the historic Mississippi River floodplain.
