Mississippi - Geography

Geography

Mississippi is bordered on the north by Tennessee, on the east by Alabama, on the south by Louisiana and a narrow coast on the Gulf of Mexico and on the west, across the Mississippi River, by Louisiana and Arkansas.

In addition to its namesake, major rivers in Mississippi include the Big Black River, the Pearl River, the Yazoo River, the Pascagoula River, and the Tombigbee River. Major lakes include Ross Barnett Reservoir, Arkabutla Lake, Sardis Lake and Grenada Lake. The largest lake in Mississippi is Grenada Lake.

The state of Mississippi is entirely composed of lowlands, the highest point being Woodall Mountain, in the foothills of the Cumberland Mountains, 806 feet (246 m) above sea level. The lowest point is sea level at the Gulf coast. The mean elevation in the state is 300 feet (91 m) above sea level.

Most of Mississippi is part of the East Gulf Coastal Plain. The Coastal Plain is generally composed of low hills, such as the Pine Hills in the south and the North Central Hills. The Pontotoc Ridge and the Fall Line Hills in the northeast have somewhat higher elevations. Yellow-brown loess soil is found in the western parts of the state. The northeast is a region of fertile black earth that extends into the Alabama Black Belt.

The coastline includes large bays at Bay St. Louis, Biloxi and Pascagoula. It is separated from the Gulf of Mexico proper by the shallow Mississippi Sound, which is partially sheltered by Petit Bois Island, Horn Island, East and West Ship Islands, Deer Island, Round Island and Cat Island.

The northwest remainder of the state consists of the Mississippi Delta, a section of the Mississippi Alluvial Plain. The plain is narrow in the south and widens north of Vicksburg. The region has rich soil, partly made up of silt which had been regularly deposited by the floodwaters of the Mississippi River.
