The Mississippi River Delta is the modern area of land (the river delta) built up by alluvium deposited by the Mississippi River as it slows down and enters the Gulf of Mexico.

Here, a great deal of golden tan, rust and dark brown colored sediments can observed flowing from the lobes of the delta into the gulf.

The deltaic process has, over the past 5,000 years, caused the coastline of south Louisiana to advance gulfward from 15 to 50 miles (24 to 80 km).

It is a biologically significant region, comprising 3 million acres (12,000 kmĀ²) of coastal wetlands and 40% of the salt marsh in the contiguous United States.

It is also a commercially significant region, supporting the economy of New Orleans with significant shipping traffic, providing 16 to 18 % of the US oil supply, and providing 16 % of the US’s fisheries harvest, including shrimp, crabs, and crayfish.
