When I first look at these Titan pictures, I think: I'm looking at a low quality picture of the California coast line with the Pacific Ocean in the foreground, waves crashing on the coast and mountain ridgelines in the background. From the direct overview pictures, what I thought looked like mountain ridgelines looks like a river delta. However when I go back and look at what I thought was the Pacific Ocean, I find myself thinking: "That sure looks like lunar maria". I don't know what I'm looking at.

One thing is for sure. That close up picture from Titan's surface of ice rocks sure looks like the Venusian surface seen from the Soviet Venera spacecraft (bone dry). I wish Huygens had landed in liquid or at least showed a puddle or stream nearby. Maybe the chemical analysis of Titan's atmospheric components might resolve some of these issues.
