Arizona history is rich in legends of America's Old West. It was here that the great Indian chiefs Geronimo and Cochise led their people against the frontiersmen. Manufacturing has become Arizona's most important industry. Principal products include electrical, communications, and aeronautical items. The state produces over half of the country's copper.
Agriculture is also important to the state's economy.
In 1973 one of the world's most massive dams, the New Cornelia Tailings, was completed near Ajo. State attractions include the Grand Canyon, the Petrified Forest, the Painted Desert, Hoover Dam, Lake Mead, Fort Apache, and the reconstructed London Bridge at Lake Havasu City.
