Geologists take to Twitter to save beloved rock
California geologists enlist the Twitter ranks in the fight to save their state rock from lawmakers and advocates.
DEFROCK THE ROCK: Serpentine, the official state rock of California.

(According to the bill, California was the first state, in 1965, to name an official rock.) Asbestos occurs naturally in many minerals, and indeed some serpentine rocks do serve as a host for chrysotile, a form of asbestos. But geologists say chrysotile is less harmful than some other forms of asbestos, and would be a danger — like scores of other rocks — only if a person were to breathe its dust repeatedly." 'There is no way anyone is going to get bothered by casual exposure to that kind of rock,’ said Malcolm Ross, a geologist who retired from the United States Geological Survey in 1995. ‘Unless they were breaking it up with a sledgehammer year after year.’”
