Nov. 20, 1980: Lake Peigneur, Lousiana is the site of a bizarre environmental accident. A Texaco oil drilling rig working on the lake’s surface punches through the roof of a Diamond Crystal salt mine beneath the lake.

Two oil rigs, several barges, a tugboat, and about 65 acres of previously-dry land are sucked into the hole.
