The 100 m false-colour image of 26 March 2015 shows us the Mississippi River Delta, also know as birdfoot. The modern Mississippi River Delta formed over the last approximately 7,000 years as the Mississippi River deposited sand, clay and silt along its banks and in adjacent basins. The Mississippi River Delta is a river-dominated delta system, influenced by the largest river in North America. The shape of the current birdfoot delta reflects the dominance the river exudes over the other hydrologic and geologic processes at play in the northern Gulf of Mexico. Prior to the extensive leveeing of the Mississippi River that began in the 1930s, the river avulsed its course in search of a shorter route to the Gulf of Mexico approximately every 1,000-1,500 years. The prehistoric and historic delta lobes of the Mississippi River Delta have influenced the formation of the Louisiana coastline and led to the creation of over 4 million acres of coastal wetlands.
