Ha, I knew you must be referring to Titan the moment I saw the it being referred to as Lacus (an IAU nomenclature practice for small bodies of fluid, Mare for large). It was one of the first first bodies of methane-ethane discovered on the moon, back in 04-05. This one is located almost exactly at the South Pole.
