In 1958, Terah Smiley suggested that Sunset Crater Volcano erupted in A.D. 1064, a date now entrenched in the literature and important in reconstructing prehistoric human response to the eruption. The first is the park’s namesake, a 1000-foot-tall (305 m) cinder cone that erupted sometime around 1085 CE. Agriculture began here because cinder from nearby volcanoes trapped water in soil. 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.

Less than a thousand years ago, around 1085 CE, Sunset Crater Volcano erupted, spewing red-hot rock and fire up to 850 feet into the air. Colton saved the cone from severe damage by averting the attempt of a Hollywood movie company to blow it up in order to simulate an eruption. Runny basalt magma had mixed with water underground, and when this reached the Earth's surface the water transformed to steam, causing the liquid rock to explode into the air. The population moved to a new environment at a lower elevation just a few tens of kilometers away, which required them to enact technological changes that allowed the population to thrive.
