Titan's south pole
Titan's south pole Titan's south pole is considerably drier than the north pole, as this RADAR image from Cassini's 20 December 2007 (T39) flyby proves. The swath is about 760 kilometers long by about 150 kilometers wide, and contains rugged mountains interspersed with flat-floored basins. Only two apparent lakes are contained in the image, a contrast to the dozens of lakes visible in north polar images. The difference probably has to do with the current season on Titan; it was the end of summer at the south pole and end of winter at the north pole during most of Cassini's primary mission to the Saturn system.
