and dumped over degraded oil on LA beaches

From SaveOurShoresFlorida: The sand covering most of the beach was of a much different consistency from the beach closer to the water (very gritty and filled with broken shells). There were lots of piles of sand dumped on the beach as well as the sand covering everything else. After shooting this video, two local deputies, who came to escort us off the beach, confirmed that BP had been trucking in sand to the beach and smoothing it over.

The bottom layer of sand is very tarry in some places and very thick and hard in others. The degraded oil is forming a hard layer a few inches under the dumped sand.
