Driftwood and seashells glazed with rust-colored tar lined the surf along the Gulf Coast's once-pristine white sand beaches Saturday, the crude from a busted oil well deep underwater showing up in greater quantities and farther east.

A cap placed over the gusher was collecting only a fraction of the oil, which had stained beaches with a waxy mess of tar balls and created an unusual orange foam in the surf.

In Gulf Shores, Ala., wooden boardwalks leading to beachfront hotels were spotted with oil from beachgoers' feet, and some condominiums were providing solvents for guests smeared with the brown goo. At Pensacola Beach, the retreating high tide left an orange stain in its wake.

Erin Tamber moved to the beach area after surviving Hurricane Katrina in New Orleans, where she had lived for 30 years.

"I feel like I've gone from owning a piece of paradise to owning a toxic waste dump," she said as she inspected the beach Saturday morning.

President Barack Obama pledged Saturday in his weekly radio and Internet address to fight the spill with the people of the Gulf Coast. His words for oil giant BP PLC were stern: "We will make sure they pay every single dime owed to the people along the Gulf coast."

Six weeks after an April 20 oil rig explosion killed 11 workers, BP has failed to significantly stem the worst spill in U.S. history. The government's point man for the crisis, Coast Guard Adm. Thad Allen, said at a news briefing Saturday that the cap had collected about 252,000 gallons of oil in its first full 24 hours of use.

The goal is to gradually raise the amount being captured, Allen said. The device's daily capacity is 630,000 gallons. The well has leaked 22 million to 47 million gallons of oil since the crisis began, according to government estimates.

The widening scope of the disaster deepened the anger and despair just as Obama arrived for his third visit to the stricken Gulf Coast.

On Obama's trip to the Grand Isle on the Louisiana coast, his motorcade passed a building adorned with his portrait reminiscent of posters of him during his presidential campaign. Instead of "hope" or "change," the words "what now?" were on his

forehead.

The oil has reached the shores of Louisiana, Mississippi,

Alabama and Florida. It has turned marshlands into death zones for wildlife and stained beaches rust and crimson. Some said it brought to mind the plagues and punishments of the Bible.

"In Revelations it says the water will turn to blood," said P.J. Hahn, director of coastal zone management for Louisiana's Plaquemines Parish. "That's what it looks like out here - like the Gulf is bleeding. This is going to choke the life out of everything."

He added: "It makes me want to cry."

The mayor of Grand Isle, David Camardelle, choked up as he told the president of staying up nights worrying.

"We don't know what's going to happen tomorrow," Camardelle said. "I'm trying to keep Grand Isle alive."

A device resembling an upside-down funnel was lowered over the blown-out well a mile beneath the sea to try to capture most of the oil and direct it to a ship on the surface. But crude continued to escape into the Gulf early Saturday through vents designed to prevent ice crystals from clogging the cap. Engineers hoped to close several vents.

As the operation went on at the bottom of the Gulf of Mexico, the effect of the BP spill was increasingly evident.
