"Before" and "after" photos show the loss of sand
on Louisiana's Raccoon Island caused by Hurricane
Andrew in 1992. More than a mile of previously
existing sandy beach (above) was removed by the
hurricane, leaving behind a patchy island
formation (below). The remaining island shown
close up in the picture on the bottom is bordered
in a rectangle in the picture on the top and is
all that remains of the original island.
