The DISR team has released an animation showing the topography near the Huygens landing site. The topography was derived from DEM-models created by using stereo observations of various regions on the surface of Titan as Huygens descended. The area shown above, topography from the movie on the left, a frame from Huygens on the right for context, shows the "shoreline"region observed by Huygens. You can see that the dark material near the bottom of the frame is definitely lower in altitude than the bright terrain. In addition, there appears to be a cliff associated with the dark channel near the top of the DEM model. Topography within the bright material is a bit hard to interpret but it is obvious that the topography and the morphology of the dendritic channels indicate flow from bottom to top, away from the "shoreline".
It should be emphasized that all the features seen in Huygens images are SURFACE features. Not fogs. Not clouds. Not giant animals. Surface features. I know people have occasional seen features move on the surface or features look like waves, but so far nothing has indicated standing liquid from the spectra or surface analyses.
