Ranger 9 camera B image of the northeast rim of Alphonsus crater at left, and southern rim of Ptolemaeus crater at the top. The image was taken from 700 km distance about 4.5 minutes before impact in Alphonsus crater. The intersecting crater rims exhibit a chaotic, mountainous terrain, in sharp contrast to the flat crater floors. The frame is approximately 120 km across and north is at 12:30. The image is centered at 12 S, 1 W. (Ranger 9, B035)
