Assumption sinkhole swallows more trees (Video) Assumption sinkhole swallows more trees (Video) Advocate staff report Sept. 12, 2013 Comments The Assumption Parish sinkhole swallowed about a dozen trees overnight Friday in a “slough-in” similar to the one captured on video several weeks ago that drew national media attention. Slough-ins occur when the bank of the nearly 25-acre sinkhole steepens, causing trees bordering the pond to pitch downward into the water, said John Boudreaux, director of the parish Office of Homeland Security and Emergency Preparedness. Boudreaux said the latest sloughing incident consumed a patch of land roughly 50 feet by 75 feet in size on the north side of the sinkhole between the Bayou Corne and Grand Bayou communities, including Texas Brine Co.’s only remaining work pad. “They did see some seismic activity yesterday (Friday) and gave us the warning that there was some activity,” Boudreaux said Saturday, adding, “and sure enough, it did go in.” A video posted on YouTube depicts the aftermath of the slough-in, though it lacks the drama of the footage shot Aug. 21 that shows tall trees plunging downward and disappearing into the insatiable sinkhole. The sinkhole has been growing since it emerged from the swamps sometime late on Aug. 2, 2012, or Aug. 3, 2012, as the suspected result of a salt dome cavern failure deep underground months beforehand.
