A slurry-filled sinkhole in the Bayou Corne area of Louisiana’s Assumption Parish that first developed earlier this month now reaches 476 feet (NE to SW) by 640 feet (NW to SE), stretching 300 feet at its deepest as of August 15.
While the sinkhole continues to expand, its exact cause remains unknown, a representative from the Department of Environmental Quality tells ENR. However, speculation has pointed to a nearby brine mining cavern that was capped and abandoned by Texas Brine Co. in 2011 after nearly two decades of operation.
