Arizona's Volcanoes

Arizona is home to two large volcanic fields. This one surrounds the San Francisco Peaks, mostly north of Flagstaff, Arizona. The second one is called the Springerville Volcanic Field and is one of the largest in the continental U.S. The San Francisco Volcanic Field covers about 1,800 square miles and and has hundreds of volcanoes including the San Francisco Peaks, with Humphreys Peak at 12,633 the highest point in Arizona. The Field also includes Sunset Crater, the most recently active volcano in Arizona. None of the volcanoes are presently active, but they cannot be considered dormant. We love the high peaks because they are visible from most of northern Arizona. If you look carefully at a photo of the Grand Canyon taken from the North Rim, you can see the mountains in the distance almost 100 miles away. I have hiked to the top of Humphreys several times and the views are spectacular.
