ON THE GULF OF MEXICO: Black Hawk helicopters peppered Louisiana's barrier islands with 1-ton sacks of sand Monday to bolster the state's crucial wetlands against an epic oil spill, 4 million gallons (15.14 million liters) and growing, in the Gulf of Mexico.
At the site of the ruptured well a mile (1.6 kilometer) below the surface, a remote-controlled submarine shot chemicals into the maw of the massive undersea leak to dilute the flow, further evidence that BP expects the gusher to keep erupting into the Gulf for weeks or more.
