    Read this about the Geology:

    Here where the Santa Monica Mountains meet
    the Pacific Ocean, the coastline varies from
    rocky bluffs to smooth sandy beaches.
    Coastal development has interrupted natural
    erosional and depositional cycles, as has the
    construction of debris basins to prevent
    landslides in the mountains. Therefore, sand
    deposited on the beaches by the sea and
    mountains is often supplemented by exotic,
    trucked-in sand that originates in such urbanized
    formations as the San Fernando Valley.

    So the sand there may not be the original sand. What about contacting:
