Many Americans are more familiar with the beginning of the Mississippi River― its source at Lake Itasca in Minnesota―than they are with its remarkable end. Fittingly, the Mississippi River brings its 4,000-mile journey through ten states to a spectacular finale at the Gulf of Mexico. This end point of the Mississippi River, known as the “Delta,” is an awe-inspiring phenomenon that contributes not only to the beauty of the region, but also serves to protect Louisiana communities from storm surges.<\/p>\n

The Delta of the Mississippi River is a peculiarly immense landform sitting between the river and the Gulf. This ecologically unique region spans nearly 8,000 miles, making it larger than the state of Massachusetts. This area is divided into three primary subdeltas: the Atchafalaya, the Teche, and the Bird’s Foot Delta. Of the three, the most famous is the Bird’s Foot Delta because it nearly ends in a fan shape. Federal regulations prevent disturbance in the Delta, allowing for the growth of thousands of plants, shrubs, and trees. This diverse environment serves as a critical stop for many species of waterfowls, and in addition to containing a large number of wildlife, wetlands in the Delta area are also a significant source of food.<\/p>\n

The science behind the formation of the Delta is equally as impressive as its beauty. To understand the Mississippi Delta’s unique shape and land form, it is important to understand the pathways of the mighty Mississippi. The Mississippi River transitions from a channelized state to a distributary into the deltaic plain when the river interacts with its coastal waters. This mix of freshwater and saltwater creates a unique sedimentary environment of silt and clay. Over time, the mixture of these sedimentary inputs form braided bayous and large lakes and ponds, ultimately creating the sprawling Delta.<\/p>\n

The importance of the Delta, both economically and environmentally, is substantial. Its expansive wetlands provide scenic beauty and bring in international tourism dollars and the economic power of the sportsman’s industry. Vast expanses of wetlands also help protect coastal communities from storms and surges, making it a valuable defense against natural disasters.<\/p>\n
