Rampart and rim features around a lake on Titan
These images provide a view of rampart and rim features near a lake on Saturn's moon Titan as observed by the international Cassini mission.
Right: Cassini RADAR image of one of Titan's lake, Viedma Lacus, obtained using the instrument's Synthetic Aperture Radar (SAR) Imager. Yellow arrows indicate portions of the raised rim near the lake, while cyan arrows indicate portions of the perimeter of the rampart feature that encloses nearly the entire lake.

Bottom left: Illustration of a lake with rampart and rim features. Rims involve higher slopes and are confined to within a few km of the lake, while ramparts enclose the entire lake and form broader mounds, up to tens of km.
