About Louisiana

Location map of Louisiana state USA
Where in the United States is Louisiana? Location map of Louisiana in the US.

Louisiana is one of the 50 states in the US, located in the West South Central region of the mainland, between Texas and Mississippi, and south of Arkansas. The state features 4,800 km (3,000 mi) of twisty, meandering shorelines along the Gulf of Mexico in the south.

The Sabine River forms two-thirds of the border with Texas, the Mississippi and the Pearl River define sections of the border with the state of Mississippi.

Louisiana originally designated the vast region of the Mississippi basin, which the French explorer La Salle claimed for France in 1682. The French sold the land to the USA as part of the Louisiana Purchase of 1803. The smaller area now known as Louisiana became the 18th state of the USA in 1812.

Short History

Louisiana Topographic Regions Map Topographic Regions Map of Louisiana. (Click the map to enlarge)
Groups of indigenous peoples have inhabited the territory of what is now Louisiana for at least 5,500 years. Archeologists have identified more than 100 sites belonging to this mound-builder culture, which also formed an extensive trade network in the eastern part of what is now the United States.

The Watson Brake archaeological site in present-day Ouachita Parish is considered the oldest earthwork mound complex in North America, dating back about 5400 years ago.

First European explorers came to visit Louisiana in 1528 when Spanish conquistadors led by Panfilo de Narváez located the mouth of the Mississippi River. In the late 17th century, French and French Canadian expeditions established footholds on the Mississippi River and the Gulf Coast.

With the Louisiana Purchase in 1803, the United States acquired almost all of the territory of Louisiana from France. Louisiana was admitted to the union on 30 April 1812 as the 18th state.

Some Geography

With a total area of 135,658 km² (52,378sq mi) [1], the Pelican State (Louisiana's official nickname) is about half the size of Colorado or somewhat larger than Greece.

There are no counties in Louisiana; the state is divided into 64 parishes.

Louisiana's landscape is mostly flat; the highest point is Driskill Mountain, the hill with an elevation of  163 m (535 ft) is the highest natural summit in the state, located 80 km (50 mi) east of Shreveport.

The state's geography offers a coastal marsh, known as the wetlands of Louisiana, a water-saturated coastal swamp region of bayous (more or less standing water) and cheniers (ridges) in the southern part of the state.
But the wetlands of Louisiana in the Mississippi Floodplain have suffered severely from human interference in the last decades. Other features of Louisiana's landscape are the Red River Valley, the Terraces, and the Hills.

The Poverty Point National Monument is a vast area of earthen architecture built by an ancient indigenous hunter-gatherer society that inhabited the region of the Lower Mississippi Valley.

The monument consists of a complex of earthworks constructed 3,700-3,100 years ago in the Late Archaic period. It is the oldest ancient earthwork of this size in the Western Hemisphere. Poverty Point was more or less abandoned around 1100 CE.
