Cerberus Palus is a plain in the Elysium quadrangle of Mars, centered at 5°48′N 148°06′E / 5.8°N 148.1°E / 5.8; 148.1.
[1] Cerberus Palus once contained a lake fed by Athabasca Valles and draining into Lethe Vallis.
[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.
