The Sunset Crater eruption is considered from paleomagnetic evidence to have begun about 1080-1150 CE. The Bonito lava flow in the foreground originated from Sunset Crater, the cinder cone in the background. The Sunset Crater eruption produced a blanket of ash and lapilli covering an area of more than 2100 sq km and forced the abandonment of settlements of the indigenous Sinagua Indians.
