The U.S. Geological Survey turned to Sandia National Laboratories  for help when the earth opened up last month near Bayou Corne, La.
Sandia’s David Borns is providing technical evaluations in weekly teleconferences about possible causes and remedies for a 300-foot-wide sinkhole there.
The sinkhole opened up overnight on Aug. 2 off the western edge of the salt dome near Bayou Corne. It was reportedly originally about 300 feet deep, but Borns said only one part was that deep; the rest was about 50 feet deep.
