Sunset Crater at the upper right is seen in this aerial view along a 10-km-long eruptive fissure extending to its SE. An eruption from Gyp Crater, immediately behind the left rim of the snow-dappled Pleistocene Double Crater in the foreground, occurred along the SE-trending fissure. Snow-capped San Francisco Mountain appears in the background at the upper left.
