SL2-05-397 (22 June 1973) --- New Orleans, Louisiana, Mississippi River, and Lake Pontchartrain (31.0N, 91.0W) can all be seen in this single detailed view. The marshlands of the Atchafalaya Basin, previously the main drainage way for the Mississippi River, can be seen to be partially silted as a result of sediments. The long narrow field patterns fronting on the river is called the "Long Lot" system of equal land distribution based on the French Napoleonic Civil Code. Photo credit: NASA
