This area lies principally along the Gulf of Mexico and the Mississippi River, which traverses the state from north to south for a distance of about 600 miles (1,000 km) and empties into the Gulf of Mexico; the Red River; the Ouachita River and its branches; and other minor streams (some of which are called bayous).The breadth of the alluvial region along the Mississippi is from 10 to 60 miles (15 to 100 km), and along the other rivers, the alluvial region averages about 10 miles (15 km) across.As Pangea split apart, the Atlantic Ocean and Gulf of Mexico opened.Louisiana slowly developed, over millions of years, from water into land, and from north to south.The state may properly be divided into two parts, the uplands of the north, and the alluvial along the coast.The alluvial region includes low swamp lands, coastal marshlands and beaches, and barrier islands that cover about 20,000 square miles (52,000 km).Before the American purchase of the territory in 1803, the current Louisiana State had been both a French colony and for a brief period, a Spanish one.In addition, colonists imported numerous African people as slaves in the 18th century.
In general, the northern terraces have had sufficient time for rivers to cut deep channels, while the newer terraces tend to be much flatter. Their origin can be traced back to the early Gulf of Mexico, when the shallow ocean had high rates of evaporation.
The state also has political jurisdiction over the approximately 3-mile (4.8 km)-wide portion of subsea land of the inner continental shelf in the Gulf of Mexico.
Through a peculiarity of the political geography of the United States, this is substantially less than the 9-mile (14 km)-wide jurisdiction of nearby states Texas and Florida, which, like Louisiana, have extensive Gulf coastlines.
There has never been an official language in Louisiana, and the state constitution enumerates "the right of the people to preserve, foster, and promote their respective historic, linguistic, and cultural origins." The suffix -ana (or -ane) is a Latin suffix that can refer to "information relating to a particular individual, subject, or place." Thus, roughly, Louis ana carries the idea of "related to Louis." Once part of the French Colonial Empire, the Louisiana Territory stretched from present-day Mobile Bay to just north of the present-day Canada–United States border, including a small part of what is now the Canadian provinces of Alberta and Saskatchewan.
The Gulf of Mexico did not exist 250 million years ago when there was but one supercontinent, Pangea.
