The 60-m-deep Gyp Crater in the foreground is located at about the midpoint of a 10-km-long eruptive fissure extending SE from Sunset Crater, the unvegetated cinder cone at the left-center. Paleomagnetic evidence places the age of the Sunset Crater eruption at between about 1080 and 1150 CE. O'Leary Peak, a Pleistocene lava dome, forms the prominent peak in the right background.
