Course of Mississippi River Through Arkansas, Mississippi and Lousiana, USA
The Mississippi River, 3,779 km (2,348 mi) long, is the second longest river, after the Missouri, in the United States. Its triangular drainage area, covering about 40% of the country and including all or part of 31 states, is approximately 3,250,000 sq km (1,250,000 sq mi), the third largest in the world.
This image focuses on the central and lower parts of the river’s course, as it flows across Arkansas, Mississippi and Louisiana, and showing its mouth at the Gulf of Mexico.
Near the top of this image, the Mississippi River enters a wide (64-113 km/40-70 mi), low valley that was once an embayment of the Gulf of Mexico. Sediment has filled this area, and through the centuries the river has extended its mouth to the present location 966 km (600 mi) downstream.
