Abstract

Of more than 400 filled lakes now identified on Titan,the first and largest reported in the southern latitudes isOntario Lacus, which is dark in both infrared andmicrowave. Here we describe recent observations includingsynthetic aperture radar (SAR) images by Cassini's radarinstrument (l = 2 cm) and show morphological evidencefor active material transport and erosion. Ontario Lacuslies in a shallow depression, with greater relief on thesouthwestern shore and a gently sloping, possibly wavegeneratedbeach to the northeast. The lake has a closedinternal drainage system fed by Earth-like rivers, deltasand alluvial fans. Evidence for active shoreline processes,including the wave-modified lakefront and deltaicdeposition, indicates that Ontario is a dynamic featureundergoing typical terrestrial forms of littoral modification.
