Louisiana Sinkhole Swallows Giant Trees

Officials have been watching for more than a year as a sinkhole in Louisiana's Assumption Parish expands and engulfs land, swamp, and threatens homes. The sinkhole, discovered August 3, 2012, resulted from a collapsed underground salt dome cavern about 40 miles south of Baton Rouge.
It took just seconds for the sinkhole to swallow several giant trees. The parish's emergency management department caught it on video.
