Deep sinkhole in Louisiana

A nearly 400-foot deep sinkhole in Louisiana has swallowed all of the trees in its area and enacted a mandatory evacuation order for about 150 residences for fear of potential radiation and explosions.

The 400-square-foot gaping hole is in Assumption Parish, La., about 50 miles south of Baton Rouge.
The sinkhole sits in the middle of a heavily wooded space where it has consumed all of the soaring cypress trees that had been there.

Flyover photos show some of the treetops still visible through the mud.

Authorities enacted a mandatory evacuation for between 100 and150 homes in the area, but most people have chosen to stay, according to the Mayor's Office of Emergency Preparedness. If any of the dangers seem to become more imminent, the order will be escalated to a forced evacuation.

While officials are not certain what caused the massive sinkhole, they believe it may be have ben caused by a nearby salt cavern owned by the Texas Brine Company.

After being used for nearly 30 years, the cavern was plugged in 2011 and officials believe the integrity of the cavern may have somehow been compromised, leading to the sinkhole.

The Supreme Court upheld President Barack Obama's health care law on Thursday, but Louisiana Gov. Bobby Jindal, a possible Republican vice presidential contender who has refused to establish a federally mandated health care exchange in his state, said Friday that he will continue to ignore it.

"We're not going to start implementing Obamacare," Jindal said during a conference call with Virginia Gov. Bob McDonnell. "We're committed to working to elect Gov. Romney to repeal Obamacare."

Under the Affordable Care Act, states must set up a health insurance exchange program by Jan. 1, 2014, and will receive grants from the federal government to implement it. Several Republican governors, including both Jindal and McDonnell, have put off setting up the exchanges in the hope that the law would be repealed or struck down by the court. Now that the law has been upheld, Jindal said he won't change course and is looking to presumptive Republican presidential nominee Mitt Romney to lead the repeal effort if he takes office in 2013.

"Here in Louisiana we have not applied for the grants, we have not accepted many of these dollars, we're not implementing the exchanges," Jindal said. "We don't think it makes any sense to implement Obamacare in Louisiana. We're going to do what we can to fight it."
