    How A 35cm Hole Created A 400m Deep Saltwater Lake

    Lake Peigneur is located in Louisiana near the Gulf of Mexico. Before 1980, it was an approximately 10-foot (3m) deep fresh water lake with an island in the middle. Next to it, and partially under it, Diamond Crystal Salt Company maintained a salt mine, with salt being mined near the lake since 1919.
