HOUSTON (Reuters) - The outer edge of a massive oil spill in the Gulf of Mexico washed up to wildlife refuges and seafood grounds on the Louisiana coast on Friday, as efforts redoubled to avert what could become one of the worst U.S. ecological disasters.
The last flight by a Coast Guard plane on Thursday had situated the thin surface "rainbow sheen" of the slick just 10 metres (33 feet) from the Pass-a-Loutre wildlife reserve in Louisiana. It seemed inevitable that some of the oil would reach shore, although the Coast Guard was awaiting information from its first Friday morning flight, a spokesman said.
