By serendipitous coincidence, today's EPOD (Earth science Picture Of the Day) may explain, a little.
http://epod.usra.edu/ (24/11/2014, OR 11/24/2014, you choose)
It shows South Eastern Greenland from 32,000 ft up, from a commercial passenger jet, taken by the Captain! (What, me worry?)
And it shows relatively flat areas of ice between mountain peaks. The flat areas are glaciers, and they seem to creep up the valleys between the mountians, well above the flat, lake like surface further from the mountains. So perhaps some of the apparently sloped 'lakes' on Titan are semi-liquid glaciers of methane? As if I knew anything about the properties of methane at minus whatever it is.
