This pair of true- and false-color images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite shows the Mississippi River running lengthwise through the center. The main river channel is surrounded by numerous branches and smaller channels, which once supported a vast wetland ecosystem that bordered the river along its length. Now most of that wetland has been converted to agricultural land.
In the false-color images, vegetation is bright green, water is dark blue or black, and waters with high volumes of sediment are bright blue.
