Sunset Crater National Monument lies a short drive north of Flagstaff in northern Arizona. The National Monument of course was created around its namesake, the extinct 800 year old cinder cone.
Flagstaff lies near the eastern edge of a 50 mile wide string of volcanic features called the San Francisco Volcanic Field. Sunset Crater is merely the most recent in a long string of eruptions. When will the next one occur? The U.S. Geological Survey has the area wired up with seismographic equipment to detect any earthquakes deep within the Earth’s crust that precede any eruptive activity. All is quiet.
Photo location: Bonito Park on the Coconino National Forest, along the entrance road to Sunset Crater National Monument, north of Flagstaff, Arizona.
