Why don't you try going to JPL's website for info on Titan?

"This is a list of named geological features on Saturn's moon Titan. Official names for these features have only been announced very recently, as Titan's surface was virtually unknown before the arrival of the Cassini probe. Some features were known by informal nicknames beforehand; these names are noted where appropriate. Contents [hide] 1 Albedo features 1.1 Bright albedo features 1.2 Dark albedo features 2 Arcūs 3 Craters 4 Faculae 5 Fluctūs 6 Flumina 7 Lacus 8 Large ringed features 9 Maculae 10 Regiones 11 Virgae 12 Informal names for unnamed features" Source and further information: http://en.wikipedia.org/wiki/List_of_geological_features_on_Titan

Intermixed with the peaks are dark, flat areas that might be lakes or playas (dry lake beds). "The radar doesn't tell us if it's liquid, but between the hills are some flat plains," Lunine said.

"It's not like the Rocky Mountains, where you've got this huge chain that stretches for a very long distance," Lunine said. It's still rugged terrain, though. "I wouldn't want to drive a rover over that stuff," said fellow Titan researcher Ralph Lorenz via email. "We expected from early low-resolution radar data that Xanadu had to be rough," added Lorenz, also of the Lunar and Planetary Laboratory. "So for once—Titan has given us so many surprises—we got something right." Sand Dunes Xanadu appears to rise above a dry surrounding lowland. On one side Xanadu is bounded by vast, spreading sand dunes, similar to those seen on other parts of Titan (read "Saturn Moon Has Seas of Sand, Images Reveal" [May 4, 2006]). But the dunes don't resume on Xanadu's far side. "It seems that Xanadu is interrupting the wind flow," Lunine said The next radar-mapping flyby is scheduled for tomorrow, when Cassini will pass over Titan's far north, where scientists hope to find lakes of liquid methane. All told, Cassini is scheduled to do radar flybys of about 20 to 25 percent of Titan's surface—a number that might be stretched to 30 percent if the orbiter doesn't suffer a major breakdown. But don't expect Cassini to reveal all of Titan's secrets. "Every pass looks different," Lunine said. "If you covered only 30 percent of the Earth, think of all the things you would have missed." "It really [shows] how varied Titan's landscape is," Lorenz said. "You have these dark plains with sand dunes around much of the equator, and then on the leading face of Titan, you hit this 'continent' of rugged mountains. It really argues for further exploration by a balloon or other aircraft that can visit all these terrains." Steve Wall of NASA added in a statement, "We have a newly discovered continent to explore, just like the early explorers of America." Geography of titan: http://news.nationalgeographic.com/news/2006/07/060721-saturn-titan_2.html Possible Oceans: NASA's Cassini spacecraft has discovered evidence that points to the existence of an underground ocean of water and ammonia on Saturn's moon Titan. The findings, made using radar measurements of Titan's rotation, will appear in the March 21 issue of the journal Science. "With its organic dunes, lakes, channels and mountains, Titan has one of the most varied, active and Earth-like surfaces in the solar system," said Ralph Lorenz, lead author of the paper and Cassini radar scientist at the Johns Hopkins Applied Physics Laboratory in Laurel, Md., "Now we see changes in the way Titan rotates, giving us a window into Titan's interior beneath the surface." Members of the mission's science team used Cassini's Synthetic Aperture Radar to collect imaging data during 19 separate passes over Titan between October 2005 and May 2007. The radar can see through Titan's dense, methane-rich atmospheric haze, detailing never-before-seen surface features and establishing their locations on the moon's surface. Using data from the radar's early observations, the scientists and radar engineers established the locations of 50 unique landmarks on Titan's surface. They then searched for these same lakes, canyons and mountains in the reams of data returned by Cassini in its later flybys of Titan. They found prominent surface features had shifted from their expected positions by up to 30 kilometers (19 miles). A systematic displacement of surface features would be difficult to explain unless the moon's icy crust was decoupled from its core by an internal ocean, making it easier for the crust to move. "We believe that about 100 kilometers (62 miles) beneath the ice and organic-rich surface is an internal ocean of liquid water mixed with ammonia," said Bryan Stiles of NASA's Jet Propulsion Laboratory in Pasadena, Calif. Stiles is a contributing author to the paper. The study of Titan is a major goal of the Cassini-Huygens mission because it may preserve, in deep-freeze, many of the chemical compounds that preceded life on Earth. Titan is the only moon in the solar system that possesses a dense atmosphere. The moon's atmosphere is 1.5 times denser than Earth's. Titan is the largest of Saturn's moons, bigger than the planet Mercury. Oceans: http://geology.com/nasa/ocean-under-saturns-moon-titan.shtml
