The Mississippi River Delta
A relatively clear day over Louisiana shows this view of the Mississippi River Delta on May 4, 2008. This image was captured by the MODIS on the Terra satellite. The Mississippi River runs along the Louisiana/Mississippi border, which is why the border looks so squiggly. (The border is in black.) Also visible crossing Louisiana diagonally is the Red River.
The Mississippi River carries 500 million tons of sediment into the Gulf of Mexico each year. The brown sediment from the river, mixing with the blue waters of the Gulf is very visible in this image. Also visible off the Gulf is Lake Pontchartrain - which is nearly round in shape and near the Mississippi border. New Orleans (in gray pixels) sits just south of it.
