Cerberus Palus once contained a lake fed by Athabasca Valles and draining into Lethe Vallis. According to different researches, it could be a lake of water^[2] or lava.^[3] It is notable by giant plates (up to 50 km and more), similar to pack ice,^[2] but possibly pieces of lava crust.^[3] Gaps between the plates contain spiral-shaped geological features, probably lava coils.^[3][4]
