USA - April 8th, 2012

Tan sediments can be seen spilling from the Mississippi River into the Gulf of Mexico in the lower right quadrant of this image of Louisiana, USA, while the rest of the delta is flanked by darker brown sediments. 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. 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).
