I lived in SF's Inner Sunset for several years. When the old DeYoung museum was demolished and all the landscaping scraped away, the "soil" underneath was pure sand.
I noticed the same thing at my home a few blocks away -- the city had to dig a trench in the street and after they got down a few feet, there was no soil, just beautiful beach sand. A little disconcerting with SF's earthquake history.
"In Paris, the famous phrase Sous les pavés, la plage! ("under the cobblestones, the beach") was used by the May 1968 protesters to mean that it was possible to escape from a regimented life."
