California rock heads - aka geologists - are upset over plans to de-crown serpentine as the state's official rock.
Apparently, it has asbestos in it, and the bill's sponsor doesn't think asbestos is a fitting symbol for the Golden State.
The geologists have taken to Twitter to press their case that their rock is being unfairly demonized. @Yorrike tweets "California should make it's official state rock unobtanium."
