Geography of Louisiana

Louisiana is a state located in the southern region of the United States. It has a total tidal shoreline of 7,721 miles.

The landscape of Louisiana is divided into three geographic land areas:

  • Mississippi Alluvial Plain : Stretching along the Mississippi River from Arkansas in the north to the Gulf of Mexico in the south, the Mississippi Alluvial Plain consists of ridges and hollows. The Mississippi Delta lying at the mouth of the Mississippi River consists of silt deposited by the river and is the most fertile area of Louisiana.

  • West Gulf Coastal Plain : The region towards the west of the Mississippi Alluvial Plain is known as the West Gulf Coastal Plain. The area towards the south, along the gulf, is composed of barrier beaches. The northern section comprises marshlands, known as the Louisiana Prairies. Driskill Mountain, the highest point in the state, lies just forty miles from the Arkansas state line.
