When one thinks about volcanoes in the US, states in the Northwest, like Washington or Alaska, come to mind. However, Arizona might be the next location of America’s next big eruption.
The San Francisco Volcano Field is an 1800 square mile area, with Flagstaff near its center. Almost 600 volcanic cinder cones are located within the area. The most recent eruption was only 900 years ago, which is a”blink of an eye” in geologic time. Scientists expect more eruptions to occur in the area.
Sunset Crater, one of the more prominent, and best preserved, of these, is a National Park. If you haven’t been there, it’s well worth a visit.
