From Wikipedia, The Free Encyclopedia: Southwest Pass is one of the channels at the mouth of the Mississippi River. It empties into the Gulf of Mexico at the southwesternmost tip of the Mississippi River Delta. It lies in Plaquemines Parish in southeastern Louisiana in the United States. It has been the main shipping channel in the Mississippi River Delta since 1853. Many lighthouses have been built for this pass. The lighthouse pictured below was in use from 1965 through 2007 - courtesy of the U.S. Coast Guard. Southwest Pass should not confused with a strait in Vermilion Parish, Louisiana, also known as Southwest Pass.
