Gulf Coast of the United States Pensacola, St. Petersburg, Tampa, and increasingly, Sarasota. All are the centers of their respective metropolitan areas and contain large ports. (Baton Rouge is relatively far from the Gulf of Mexico; its port is on the Mississippi River, as is the port of New Orleans.) The Gulf Coast is made of many inlets, bays, and lagoons. The coast is also intersected by numerous rivers, the largest of which is the Mississippi River. Much of the land along the Gulf Coast is, or was, marshland. Ringing the Gulf Coast is the Gulf Coastal Plain which reaches from Southern Texas to the western
Structural evolution of the Louisiana gulf coast The observation of minibasins (small sedimentary basins) and other features have suggested that the salt in the Gulf of Mexico primarily moves by spreading under differential sedimentary loading, which needs many conditions (e.g. huge amounts of deposited material above the salt) to be met. However, models and observation of the northern Gulf of Mexico favor gliding via slope instability. Controversies such as this example indicate that this area is structurally complicated. During the Mesozoic Era, the supercontinent Pangaea began to rift apart, forming the Gulf of Mexico basin within the late Triassic and early Jurassic periods. The rifting was accompanied
