3. New Orleans’s Six Flags
New Orleans endured a majority catastrophe in 2005. The catastrophe was Hurricane Katrina, which had submerged substantial parts of the low-elevation town in water. While Six Flags isn’t the worst thing to have had shrunk, it is indicative of the larger tragedy.
This particular image, taken via drone, reveals an abandoned and underwater Six Flags amusement park. The place has been underneath the waves since the initial disaster. Unfortunately, the area has not had the tools to resurrect it.
