Arizona is home to some of the US's most stunning national parks and monuments. Jay Price tells how Arizona's parks emerged from the recreation and tourism boom of the 1950s and 1960s, were shaped by the environmental movement of the 1970s and 1980s, and have been affected by the financial challenges that arose in the 1990s. He also explains how changing political realities led to different methods of creating parks like Catalina, Homol'ovi Ruins, and Kartchner Caverns.
