California has a greater number of minerals and a wider variety
of rock types than does any other state. Serpentine, a shiny, green
and blue rock found throughout California, was named the official
State Rock in 1965. It contains the state's principal deposits of
chromite, magnesite, and cinnabar. California was the first state
to designate a State Rock.
