A spectacular landslide within the low-brightness region of Iapetus's surface, known as Cassini Regio, is visible in this image from Cassini.
In this view, north is to the left of the picture and solar illumination is from the bottom of the frame. The image was obtained in visible light with the Cassini narrow-angle camera on 31 December 2004, at a distance of about 123 400 kilometres from Iapetus. Resolution achieved in the original image was 740 metres per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility.
