Arizona's copper production since 1912

Arizona's eponymous 5 C's (copper, cattle, citrus, cotton, and climate) are not the same driving factors in the state's economy as they were a century ago when Arizona became a state. A set of feature stories by Cronkite News Service looks at each C over the past 100 years. The chart above right is greatly reduced from the story on copper. It tracks Arizona copper production since 1912 with corresponding values of annual production.
