December 14, 2011 - The alluvial fans of the Mississippi River Delta Basin
The Mississippi River drains over two-thirds of the conterminous United States, sending an enormous amount of water through the Mississippi River Delta Basin in southern Louisiana. The river's velocity slows upon reaching the Gulf, reducing its capacity to carry suspended mud and sand, depositing the sediment in vast alluvial fans as shown in the Landsat 5 mosaic above. The fan deposits are major sources of petroleum, natural gas, and sulfur. This image was created using four Landsat 5 scenes acquired October 3 and November 11.
