The two linear depressions at the bottom of today's VIS image are part of Cerberus Fossae. The features are termed graben and are formed by crustal extension that allows material to subside between paired tectonic faults. The straight sides and uniform depths are indications that these are tectonic features rather than channels caused by fluid erosion.
