re: 1980 Lake Peigneur Sinkhole, Older O&G guys, were you around for this?

Wasn't around but had family who was and heard the stories growing up. They used the wrong reference for their surface coordinates, placed the rig in the wrong location, and drilled into the mine. It sucked down the rig and barges. The river began to flow backwards and the GOM actually flowed inland for a day or so.

The barges popped back to the surface after but the rig is still down there somewhere.

It was a freshwater lake before. Now it's brackish.
