About the Map
This map represents some of Arizona’s recent volcanic history. Geologically speaking, Arizona is home to thousands of young volcanoes. The youngest, Sunset Crater, erupted around A.D. 1085. That eruption forced Native Americans to relocate to what is now Wupatki National Monument. While there are no active volcanoes in Arizona, there are volcanic fields capable of producing new volcanic activity: the San Francisco and Uinkaret volcanic fields in northern Arizona, and the Pinacate volcanic field on the Arizona-Mexico frontier. In this map, each colored area represents one of these fields. Hover over a color and click on it view a slide show and to learn more about each field. Zoom in and pan around to get a bird’s eye view of the fields.
