From CBS:

It may be the most disturbing site yet: the first heavy sludge now oozing into the marshes of Louisiana as the slick continues to grow in size out in the gulf.

CBS News correspondent Kelly Cobiella reports it’s an ominous sight. The oil is thick and black and stretches about a quarter mile down a beach. It goes beyond the booms into the sensitive marsh lands which are home to migratory birds.

Louisiana Gov. Bobby Jindal flew over it Tuesday.

“This wasn’t just sheen, we were seeing heavy oil out there,” Jindal said. “This wasn’t just tar balls. It shows you how quick the oil showed up.”

These are the same marshes that provide a barrier of protection against hurricanes.

Then there is this little tidbit:

Also on Tuesday, nearly two dozen tar balls were found off Key West, Fla., the U.S. Coast Guard said, but the agency stopped short of saying whether they came from the massive oil spill.

Isn’t BP just the greatest?
