Titan's north polar lakes exhibit variable morphologies, but common to many is that they occupy steep-rimmed depressions, often 100s of metres deep; Kirk et al. [1] measured scarp heights up to 600 m by manual feature-based stereoscopic methods (fig. 1). Lake depressions with this morphology are usually in clusters, and are found to be consistent with karstic or karst-like processes, based on terrestrial analogues and elimination of other possible modes of origin [2] including volcanic and tectonic, on the grounds of distribution, and thermokarst, on the grounds of insufficient insulation. -- Authors Open Access - Permission by Publisher See Extended description for more information.
