The serpentine has quietly held the title since 1965, explains the San Francisco Chronicle, but because it contains asbestos, lawmakers are considering a bill to defrock it as a symbolic gesture against the carcinogen. Scientists are fighting mad. "It's a wonderful state rock because it has got this great natural, social and scientific history in California," says an environmental historian. Pshaw, says the state senator who introduced the bill. "This isn't against serpentine. It's about asbestos. Why in a health-conscious state like California do we have a state rock that is related to asbestos?"
