More descent images via The Planetary Society
This one represents the view from 1.2 kilometers (4000 feet). Now the images become fuzzy because the landscape is very dark, lacking contrast, and the available light quite dim. Still, Huygens made out what looks like a ridge dissected by channels. Probably the oddest thing in this image is the ground track. It continues from west to east, but suddenly, below an elevation of 9.3 kilometers (5.8 miles), Huygens' eastward motion stalled. The probe descended, took a hairpin turn, and traveled back in the direction that it had come from!
