Before and After Photo Comparisons: Chandeleur Islands

The Chandeleur Islands are a north-south oriented chain of low-lying islands located approximately 100 kilometers east of the city of New Orleans, Louisiana. Below, photo pairs reveal the nearly complete destruction of the islands in recent hurricane seasons. The first image in each pair was taken in July 2001, before Hurricanes Lili (2002), Ivan (2004), Dennis (2005), and Katrina (2005, the strongest and closest in proximity to the Chandeleurs). The second image was taken on August 31, 2005, two days after Hurricane Katrina made landfall on the Louisiana and Mississippi coastline.

Photo showing locations of pre-and post-storm photo sets. Scroll down or click on the yellow location numbers on the photo above to view the pre- and post-storm photo sets for the Chandeleur Islands.

Location 1: The first image, taken in July 2001, shows narrow sandy beaches and adjacent overwash sandflats, low vegetated dunes, and backbarrier marshes broken by ponds and channels. The second image shows the same location on August 31, 2005, two days after Hurricane Katrina made landfall on the Louisiana and Mississippi coastline. Storm surge and large waves from Hurricane Katrina submerged the islands, stripped sand from the beaches, and eroded large sections of the marsh. Today, few recognizable landforms are left on the Chandeleur Island chain.
