This is interesting video that was forwarded to me in my Email .. It was quite fascinating, so I tossed it up onto my YouTube account .. It’s about the Lake Peigneur Disaster on November 21, 1980

The lake was previously an eleven foot shallow fresh-water lake until an unusual man-made incident on November 21, 1980. At that time, Diamond Crystal Salt Company operated the Jefferson Island salt mine under the lake while a Texaco oil rig was drilling down from the surface of the lake.


A resultant whirlpool sucked in the drilling platform, eleven barges, many trees and some of the surrounding terrain. The salt mine was so large and so able to absorb the water pouring into it that the water level dropped significantly, enough to reverse the flow of the Delcambre canal that leads to the Gulf of Mexico. This backflow created, for a few days, the tallest waterfall ever in the state of Louisiana, at 50–100 feet (15–30 m), as the lake refilled with salt water to replace the fresh water now in the salt mine.
