See this island? It wasn't here yesterday.
The Louisiana National Guard poured in tons of sand and rock to fill a 700 foot gap in a barrier island to stop the oil from reaching the estuaries.
The gap was the result of hurricane damage in Elmer's Island, just across the bridge from Grand Isle.
Filled in, the island will now be a part of the last line of defense in Louisiana's scramble to protect it's ecologically sensitive coast. The area is also an important breeding ground for shrimp.
"It's ecologically and economically very important to the local community," Lt. Kyle Galloway told CNN.
