Crews in Newport Beach, Calif., use shovels to clean up a heavy layer of oil that washed ashore after last week's spill from the tanker American Trader. The last of the oil washed ashore Thursday. "Everything has hit the shoreline. All the oil that was in the water is now on the beach," said Coast Guard Petty Officer Dennis Hall. The Coast Guard said it had no estimate of when all the oil would be cleaned up. So far the job has cost $4-million.
