The linear depressions in today's VIS image are part of Cerberus Fossae. The features are termed grabens, and are formed by extensional tectonic forces. As the regional fractures move apart, blocks of material subside between paired faults. The straight sides and uniform depths are indications that this is tectonic feature rather than a channel caused by fluid erosion. The fossae stretch for 1235km (767 miles).
